| Abstract: | Aimed at the cracking problem of solder joint between vertical beam and backboard,which occur in the road test on OTSl sample car of some freight car in Hainan,the paper is a CAE simulation analysis of car strength,which simulates bend and shifts full load with finite element analysis software.Furthermore,the paper lays out effective scheme to optimize the structure of fault zone based on the structure of vehicle types and root causes. |
