Failure analysis of crack on cold-rolled steel panels of truck cabin

This article examines the failures of cabin sheet metal panels in depth. The truck cabin segments' failures are examined in relation to one another. The failure distributions are evaluated to determine their correlation coefficients and then classified. The frequency of failures in cabin-in white (CiW) structural panels and cabin mount elastomeric bushings was determined in this investigation. Later investigation of the elastomer mount's stiffness fluctuation during field operation established that the fractures in the cabin panels were caused by the elastomer bush rotating out of position and resulting changes in transmissibility. Experiments conducted in a variety of working conditions established the existence of high stress zones predicted by finite element modeling. Finally, preventative measures are offered to avert such failures.

Automated summary

This article examines the failures of cabin sheet metal panels in depth, analyzing the correlation between failures in different segments of truck cabins. By evaluating the distribution and classifying the failures, their correlation coefficients are determined. The investigation also determines the frequency of failures in cabin-in white structural panels and cabin mount elastomeric bushings, as well as the cause of fractures in cabin panels due to elastomer mounts rotating out of position. Experimental results confirm the existence of high stress zones predicted by finite element modeling and preventive measures are proposed.
