摘要
以某轻卡纵梁连接板为研究对象,其“拐点”应力值超出材料屈服极限,开裂风险较大。基于有限元仿真分析,分别采用两种优化方案对其“拐点”区域进行球化处理,均使最大应力值低于材料屈服极限。经验证分析可知,两种优化方案分别使最大应力下降45.3%和54.8%,方案二效果更佳。
Taking a light truck longitudinal beam connection plate as the research object,its"inflection point"stress value exceeds the material yield limit,and the cracking risk is high.Based on the finite element simulation analysis,two optimization schemes are adopted to spheroidize the inflection point area,which reduces the maximum stress to below the material yield limit.According to the test and verify empirical analysis the two optimization schemes reduce the maximum stress by 45.3%and 54.8%respectively,and the effect of scheme two is better.
