Highway wind damage
0 likes83 views
A finite element analysis was conducted to simulate the effects of Category 5 hurricane winds on a highway sign. The 3D solidworks model represented the steel construction and bolted connections to concrete supports. The FEA mesh and 200 mph steady wind loading predicted over 2 inches of permanent deformation and stress exceeding the steel yield point near the base of vertical supports, indicating failure. More advanced dynamic analysis was recommended to predict vibration from wind turbulence.

Post weld heat treatment (PWHT) reduced the hardness in the heat affected zone (HAZ) to below 250 VHN, solving the HAZ hardness issue. However, PWHT caused carbon to diffuse to the fusion boundary, increasing the hardness there. Bead sequence one (BS1) welds had higher hardness values and were more susceptible to lack of fusion defects than bead sequence three (BS3) welds in all material combinations tested. The base steel 8630 also had higher hardness than F22 steel in all combinations, even after PWHT.Forquer - DMW Poster 01132015

Post weld heat treatment (PWHT) reduced the hardness in the heat affected zone (HAZ) to below 250 VHN, meeting requirements. However, PWHT caused carbon to diffuse to the fusion boundary, increasing the hardness there. The study tested different substrates (F22 and 8630 steel) and weld sequences (BS1 and BS3). BS1 had higher hardness values and was more susceptible to defects. 8630 steel had higher hardness than F22 in all combinations, even after PWHT. PWHT was able to reduce HAZ hardness but increased fusion boundary hardness due to carbon migration.Boat trailure winch bolt failure

This document is a damage stress analysis report for a bow thruster assembly that was involved in an underwater collision. It summarizes the solidworks model of the assembly, details an FEA mesh and collision simulation with a rocky bottom, and analyzes the maximum stresses on the struts. Resonant frequency analyses were also conducted, identifying three vibration modes that could lead to propeller blade flutter or collisions with the cowling. The conclusions recommend strengthening the support struts and performing qualification testing over the full speed range.Cross axis vibration
Cross axis vibrationDon Blanchet
油
This document discusses vibration testing of equipment and whether cross-axis motion during testing is significant. It notes that vibration tests are usually done in three perpendicular axes but that overturning moments can cause responses in axes perpendicular to the one being excited. Modal analysis and vibration testing of a laser electronics assembly showed that cross-axis responses could be a significant fraction of the in-line responses, with quality factors ranging from 4 to 58. The conclusions are that orthogonal vibration testing does not guarantee orthogonal peak responses and that fatigue calculations should include all axial responses.Ceramic cavity resonator
Ceramic cavity resonatorDon Blanchet
油
This document summarizes the assembly process for a ceramic microwave resonator cavity using a shrink fit technique. Key steps include heating the aluminum housing to expand it, inserting the ceramic puck using an alignment fixture, and allowing the assembly to cool which causes the housing to contract around the puck, holding it firmly in place through compression. Finite element analysis confirms the ceramic is held safely in compression while the housing experiences some permanent plastic deformation within its yield strength to form an interference fit.Shock sensitive components mythology
Shock sensitive components mythologyDon Blanchet
油
This document discusses myths and best practices for packaging shock sensitive electronic components. It notes that shock levels measured in G units for components do not necessarily translate to the same exposure levels for those components when mounted in a system. The document recommends establishing system-level shock requirements, obtaining component shock specifications, designing mounts, and using modeling to calculate dynamic response of components in a system. It provides an example where modeling showed a crystal oscillator experienced 70Gs of shock in a system designed for a 50G specification, due to mounting factors. It concludes systems have many dynamic factors that influence component-level responses to shock.TQFP HALT testing stress analysis

The document analyzes the potential for lead cracking in a TQFP32 package under vibration testing. A Solidworks simulation modeled the package and circuit board to determine major resonances and peak lead stresses. The simulation found a package resonance at 50kHz from lead frame and package bending. HALT testing was predicted to induce a peak lead stress of 65,000 psi, above the copper alloy's endurance limit of 20,000 psi, indicating a potential for fatigue cracking in the leads from the hammer blows.Flex coupling stress analysis

A flexible coupling for torque transmission between misaligned shafts is proposed. Finite element stress analysis was used to estimate the life of a 0.2-0.3 inch coupling made of mild alloy steel with a 0.01 inch helical cut to manage shaft misalignment. The analysis applied torque loading and misalignment conditions to determine the stress loading and distortion over the expected range of service life.Graphics card resonances

This document discusses how to increase the natural frequency of a graphics card assembly to reduce vibration. It shows that doubling the weight by adding a stiff heatsink that also provides cooling doubled the natural frequency. The goals are to increase stiffness and decrease mass to raise the ratio of stiffness to mass. A base graphics card had a frequency of 16hz, adding a retention bracket raised it to 18hz, and incorporating an aluminum heatsink and fans increased the frequency to 32hz while doubling the weight.Stiffening of a shock lab test chassis

This document discusses cordwood discrete component electronic packaging used in the 1950s-1960s. Cordwood modules involved stacking electronic components vertically in a cylindrical housing using insulating standoffs, allowing for high packaging density. Early implementations like guidance electronics in missiles had very short service lives due to high vibration levels from tactical use. Modifications like adding mounting feet and spacers could significantly increase the first modal frequency and reduce stresses, resulting in an estimated service life of over 175 hours for applications like tactical jet fighters.Drill bit life calculation

This document summarizes a study on bolt failures in a heavy steel lap shear joint. The goals were to evaluate grade 5 bolts currently in use, demonstrate sequential bolt failure, determine maximum load capacity, and calculate a safety factor for a heavy lift rigging fixture. Testing of an assembly with 8 bolts found failures at 2 bolts and 6000 lbs of load. Testing of an assembly with 6 bolts found failures at 4 bolts and 6000 lbs of load, indicating complete failure would occur at 3 tons of load. The document recommends stamping the plates with a maximum 1.5 ton load and changing to higher strength Grade 8 bolts to increase the bolt safety factor of 1.2 to an acceptable 1.5.Santa maria revisited with fea

The conclusion is that increasing the ratio to 11:1 would likely cause cracking and failure of the connecting rod.Nonlinear FEA analysis Rubber gasket

The model was meshed and subjected to a 0.035 inch displacement in the -Z direction. The results showed a maximum displacement including sliding and buckling, and a maximum stress of 234 psi, which is below the material strength of 700-800 psi.

As a case study, FEA models of a simple steel bar under tension and torsion loading were analyzed. The results found that a drilled crack stopper hole reduced maximum stress at the crack tip by 94.6% under tension and 25.4% under torsion, demonstrating how the technique can increase fatigue life.Heavy lift rigging safety analysis

Designing Flex and Rigid-Flex PCBs to Prevent FailureEpec Engineered Technologies
油
Flex and rigid-flex printed circuit boards (PCBs) can be considered at the basic level some of the most complex PCBs in the industry. With that in mind, its incredibly easy to make a mistake, to leave something out, or to create a design that was doomed from the start.
Such design failures can end up leading to an eventual failure by delamination, short circuits, damage to the flex portions, and many other things. The easiest way to circumvent these is to start at the beginning, to design with preventing failure in mind rather than trying to fix existing designs to accommodate for problems.
In this webinar, we cover how to design flex and rigid-flex PCBs with failure prevention in mind to save time, money, and headaches, and what failure can look like.
