Outline
This article mainly introduces a fast verification of the effectiveness of the optimization scheme for durability cracking of body sheet metal using a simple bench test combined with Miner principle, and then verifies it through vehicle durability testing to form a close-loop optimization method. First, reproduce the problem of body sheet metal cracking in vehicle enhanced durability testing using CAE analysis method. Then, confirm the cause of body sheet metal durability cracking and make optimization scheme. Next, through CAE simulation analysis, design a simple bench test. Through this simple bench test, it is necessary to accurately reproduce the durability cracking problem of body sheet metal, then quickly verify the effectiveness of the optimization scheme. Finally, after verification through vehicle durability testing, the body sheet metal with added optimization scheme did not show any durability cracking problem, which proves the accuracy and effectiveness of this method.
