| Abstract: | Taking the problem of the engine hood inner panel discovered in reliability test of a car as background, taking en gine hood as researching subject, finite element models of the hood were built up. Solder joint crack at the inner panel of hood and latch fixed plate was CAE analyzed, the main reasons leading to solder joint cracking were identified, several solutions were provided and an optimal solution was ultimately determined to fulfill the requirements, some thoughts and methods on design and production of engine hood were offered. |
