单面立式硬支撑动平衡测试机的设计研究

摘要

In connection with the design of Single Plane hard bearing dynamic balancing measurement ma-chine, a series of theoretical analysis was 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 with a prototype designed by the design scheme. The result demonstrates that the prototype has high measurement precision.%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。
