| 摘 要： | 针对某活塞机械疲劳试验,以某铝合金活塞为研究对象,采用有限元方法分析了在交变机械载荷作用下活塞销和活塞销座内侧之间接触状态和接触应力的变化,在此基础上确定了活塞疲劳失效的主要位置,这一数值计算结果与试验结果吻合,进而分析了接触对活塞疲劳失效的影响.

| Abstract: | The change of contact state and contact stress between piston pin and piston under the mechanical load at the mechanical experiment are calculated.The results which agree well with the results of experimental measurement can be used to locate where and why failures might happen,and the effect of contact are calculated as well. |
