弹簧疲劳试验机单空间与双空间布置试样的动力学分析

Dynamic Analysis of Single Space and Double Space Layout Specimen of Spring Fatigue Testing Machine

对弹簧疲劳试验机的弹簧试样单空间布置、双空间布置两种情况,进行静态动力学分析,得到两种布置方式下,弹簧试样产生的试验力、机构受力、摆动力矩、平衡力矩、驱动功率在曲柄匀速旋转一个周期内的变化情况。

The static dynamic analysis of the spring specimen of the spring fatigue testing machine is carried out under the conditions of single space arrangement and double space arrangement,and the changes of load,mechanism force swinging torque,balancing torque and driving power in a cycle of uniform rotation of the crank are obtained under the two arrangement modes.
