利用应变实时监测研究后桥疲劳裂纹扩展规律

Spreading of Rear Suspension Fatigue Cracks by Strain Real-time Monitoring

应用计算机技术对桑塔纳后桥疲劳试验时的应变变化进行实时监测，研究了疲劳裂纹问题．在经过多次实时监测试验后，分析了应变变化与疲劳裂纹产生。

This paper studies the issue of SANTANA rear suspension fatigue cracks by computer real-time monitoring on the strain variation. After several real-time monitoring experiments, we analyzed the relationship between strain variation and the producting and spreading of fatigue crack.
