IRJET- Dynamic Analysis on Vibration GraderIRJET Journal
油
This document describes a study on the dynamic analysis of a vibration grader using finite element analysis. A 3D model of an existing vibration grader was created and analyzed using modal and harmonic analysis to determine critical frequencies and locations of resonance. High vibrations during operation were found to reduce the machine's lifespan. The study aims to optimize the design to eliminate resonance and increase durability by performing finite element analysis on modified models. Key parts of the vibration grader including the center beam, shafts, housing, and screen assembly were modeled. Modal analysis identified critical frequencies within the operating range. Stress analysis at these frequencies and proposed design changes aim to improve the dynamic behavior and performance of the vibration grader.DESIGN OF POWER GENERATING SPEED BREAKER

This document describes the design and construction of a pendulum machine to generate electricity through oscillatory motion. It consists of a pendulum bar connected to an upper arm that oscillates and drives a rack and pinion gear system. This system is connected to a dynamometer which converts the mechanical energy to electrical energy that can be stored in a battery. When the pendulum is displaced and swings back and forth, it causes the upper arm to move up and down. This vertical motion is converted to rotational motion by the rack and pinion gears, and the dynamometer then converts this to electricity. The device aims to harness the kinetic energy of the swinging pendulum in an eco-friendly way to generate renewable electricity for small-scaleIRJET- Development of Winch Machine For Erection of Transmission Tower A Review

Once upon a time in Gujarat, Plinth and Roofs was working on a massive industrial shed project. Everything was going smoothlyblueprints were flawless, steel structures were rising, and even the cement was behaving. That is, until...
Meet Ramesh, the Stressed Engineer.
Ramesh was a perfectionist. He measured bolts with the precision of a Swiss watchmaker and treated every steel beam like his own child. But as the deadline approached, Rameshs stress levels skyrocketed.
One day, he called Parul, the total management & marketing mastermind.
Ramesh (panicking): "Parul maam! The roof isn't aligning by 0.2 degrees! This is a disaster!"
Parul (calmly): "Ramesh, have you tried... meditating?"
､ Ramesh: "Meditating? Maam, I have 500 workers on-site, and you want me to sit cross-legged and hum Om?"
Parul: "Exactly. Mystic of Seven can help!"
Reluctantly, Ramesh agreed to a 5-minute guided meditation session.
He closed his eyes.
鏝 He breathed deeply.
He chanted "Om Namah Roofaya" (his custom version of a mantra).
When he opened his eyes, a miracle happened!
ｯ His mind was clear.
The roof magically aligned (okay, maybe the team just adjusted it while he was meditating).
And for the first time, Ramesh smiled instead of calculating load capacities in his head.
Lesson Learned: Sometimes, even in industrial construction, a little bit of mindfulness goes a long way.
From that day on, Plinth and Roofs introduced tea breaks with meditation sessions, and productivity skyrocketed!
Moral of the story: "When in doubt, breathe it out!"

Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere.
Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide. Outdoor and indoor air pollution cause respiratory and other diseases and are important sources of morbidity and mortality.
WHO data show that almost all of the global population (99%) breathe air that exceeds WHO guideline limits and contains high levels of pollutants, with low- and middle-income countries suffering from the highest exposures.
Air quality is closely linked to the earths climate and ecosystems globally. Many of the drivers of air pollution (i.e. combustion of fossil fuels) are also sources of greenhouse gas emissions. Policies to reduce air pollution, therefore, offer a win-win strategy for both climate and health, lowering the burden of disease attributable to air pollution, as well as contributing to the near- and long-term mitigation of climate change.

Preface: The ReGenX Generator innovation operates with a US Patented Frequency Dependent Load Current Delay which delays the creation and storage of created Electromagnetic Field Energy around the exterior of the generator coil. The result is the created and Time Delayed Electromagnetic Field Energy performs any magnitude of Positive Electro-Mechanical Work at infinite efficiency on the generator's Rotating Magnetic Field, increasing its Kinetic Energy and increasing the Kinetic Energy of an EV or ICE Vehicle to any magnitude without requiring any Externally Supplied Input Energy. In Electricity Generation applications the ReGenX Generator innovation now allows all electricity to be generated at infinite efficiency requiring zero Input Energy, zero Input Energy Cost, while producing zero Greenhouse Gas Emissions, zero Air Pollution and zero Nuclear Waste during the Electricity Generation Phase. In Electric Motor operation the ReGen-X Quantum Motor now allows any magnitude of Work to be performed with zero Electric Input Energy.
Demonstration Protocol: The demonstration protocol involves three prototypes;
1. Protytpe #1, demonstrates the ReGenX Generator's Load Current Time Delay when compared to the instantaneous Load Current Sine Wave for a Conventional Generator Coil.
2. In the Conventional Faraday Generator operation the created Electromagnetic Field Energy performs Negative Work at infinite efficiency and it reduces the Kinetic Energy of the system.
3. The Magnitude of the Negative Work / System Kinetic Energy Reduction (in Joules) is equal to the Magnitude of the created Electromagnetic Field Energy (also in Joules).
4. When the Conventional Faraday Generator is placed On-Load, Negative Work is performed and the speed of the system decreases according to Lenz's Law of Induction.
5. In order to maintain the System Speed and the Electric Power magnitude to the Loads, additional Input Power must be supplied to the Prime Mover and additional Mechanical Input Power must be supplied to the Generator's Drive Shaft.
6. For example, if 100 Watts of Electric Power is delivered to the Load by the Faraday Generator, an additional >100 Watts of Mechanical Input Power must be supplied to the Generator's Drive Shaft by the Prime Mover.
7. If 1 MW of Electric Power is delivered to the Load by the Faraday Generator, an additional >1 MW Watts of Mechanical Input Power must be supplied to the Generator's Drive Shaft by the Prime Mover.
8. Generally speaking the ratio is 2 Watts of Mechanical Input Power to every 1 Watt of Electric Output Power generated.
9. The increase in Drive Shaft Mechanical Input Power is provided by the Prime Mover and the Input Energy Source which powers the Prime Mover.
10. In the Heins ReGenX Generator operation the created and Time Delayed Electromagnetic Field Energy performs Positive Work at infinite efficiency and it increases the Kinetic Energy of the system.Integration of Additive Manufacturing (AM) with IoT : A Smart Manufacturing A...

PROJECT REPORT ONdfervrvvrtvrvrttvr.pptx
- 1. PROJECT REPORT ON : G e n e v a M e c h a n i s m Submitted by : Group(21) Mohamed Fathy Mubarak Mohamed Abdel- monem Mohamed Mahrous Hanfy Mohamed Nasr Ibrahim Guide by : Dr.Wesam Farouk Eng. Mohamed Elshamy 5/10/2024
- 2. INTRODUCTION The Geneva drive is a gear mechanism that translates a continuous rotation into an intermittent rotary motion. The rotating drive wheel has a pin that reaches into a slot of the driven wheel advancing it by one step. The drive wheel also has a raised circular blocking disc that locks the driven wheel in position between steps.
- 8. Calculations Geneva gear auto calculating site this site is amazing! Through this site we can easily calculate Geneva gear parameters and check the motion(animation). http://benbrandt22.github.io/genevaGen/
- 13. CRITERIA FOR SELECTION OF MATERIAL: The material for different components was selected by assessing tensile strength and modulus, flexural strength and modulus, impact strength, compressive strength, fatigue endurance, creep, and stress-relaxation properties depending on the application. This ensures that design will work efficiently without any probability of failure. However, unexpected conditions like being subjected to a higher load than expected or being damaged by a chemical can affect the system. Furthermore, the cost factor is also very important in selecting material.
- 14. 1. Frame/Stand: Purpose: This is the part which bears the load of all other components as they are mounted on it. The frame material must have the capability to endure the load and offer minimum deformation Material: Steel 37
- 15. 2. Geneva Mechanism: It will consist of a Drive Wheel and a Driven wheel. Purpose: It will change continuous circular motion into fixed step circular motion. The rest of its mechanism has been explained earlier. Material: Steel 37
- 16. 3. 12V DC motor: Purpose: A DC motor is a device to convert electrical energy input to mechanical/kinetic energy output via a simple mechanism that uses magnetic field and electricity to produce a torque. The DC motor will be connected to the Geneva drive wheel, causing it to rotate due to the torque produced in it. We can control the rotation speed of the Geneva Drive wheel by varying the supplied Voltage. Greater the voltage, greater the speed of rotation
- 18. APPLICATIONS 1. Modern film projectors may also use an electronically controlled indexing mechanism or stepper motor, which allows for fast-forwarding the film. 2. Geneva wheels having the form of the driven wheel were also used in mechanical watches, but not in a drive, rather to limit the tension of the spring, such that it would operate only in the range where its elastic force is nearly linear.
- 20. ADVANTAGES Maintains good control of its load at all times. Low cost. Saves Man Power. Saves time. Easy setup in an industry. Does not require stepper motor.
- 21. DISADVANTAGES Very difficult to change timing once design is chosen. The Geneva is not a versatile mechanism. The ratio of dwell period to motion is also established. Once the no of dwells per revolution has been selected.
