The results show that the abnormal cracking of the lower beam of the water tank is due to the stress concentration at the step of the lower beam. The maximum stress in the cracked position of the step is about 294.2 MPa with the material HC340LAD+Z and yield limit 340 MPa. However, when high-cycle running (more cycle times), fatigue damage can still occur. Considering the cause of cracking, a structural optimization program was proposed. Through road test verification, the optimized structure can meet the design requirements. | | 查看全文查看/发表评论下载PDF阅读器 | |
