单面立式硬支撑动平衡测试机的设计研究

The Design Study of Single Plane Vertical Hard Bearing Dynamic Balancing Machine

针对单面硬支撑动平衡测试机,进行了机器的动力学研究,分析了影响永久标定误差的因素,给出了板簧刚度、测力传感器安装刚度和预紧弹簧刚度的选取原则,制作了样机,进行实验测试以及最小可达剩余不平衡度测定。结果表明,按照设计方法设计的测试机具有较高的测试精度。

In connection w ith the design of Single Plane hard bearing dynamic balancing measurement machine,a series of theoretical analysis w as done,including the dynamics analysis of the machine,analyzing the factors influencing permanent calibration error and presenting a stiffness principle of spring board,sensor and preloaded spring. After this,the experiments of testing and minimum achievable residual unbalance are done w ith a prototype designed by the design scheme. The result demonstrates that the prototype has high measurement precision.
