圆柱螺旋弹簧疲劳试验机的设计与实现

Design and implementation of circular coil spring fatigue test machine

弹簧疲劳寿命是对弹簧施加周期性的变载荷,在给定的失效条件下,所试弹簧达到的最大循环次数。本试验机可用于拉伸弹簧或压缩弹簧的疲劳测试,通过拉压力传感器和位移传感器,实时保存并分析相关数据完成弹簧的疲劳试验。通过对圆柱螺旋弹簧疲劳试验机的设计,最终实现了试验样机的研制。

The spring fatigue life is the maximum number of cycles that a periodic variable load is applied to the spring under a given failure condition. The test machine can be used to the spring fatigue test not only stretch but also compression the spring, the spring fatigue test can be carry by save and analysis the real-time data of the pull pressure sensor and displacement sensor, and ultimately complete spring fatigue test. The prototype was developed with the design of the cylindrical coil spring fatigue testing machine.
