具有三自由度的接触器动态特性测试系统设计及实现

摘要

Quick lock, switch of measuring target for laser displacement sensor in the three-dimensional degree and quick in-stallation of contactors were realized by the design of mechanical structure for contactor test -system.Therefore, the test efficiency of contactor's dynamic characteristic was improved .The system includes removable testing mechanism and adjustable installation mechanism.The integration all modules used for testing dynamic characteristics parameters with three -axis slide used for locking measured target within three-dimensional degree in the removable testing mechanism makes multiple parameters of contactor 's dy-namic characteristics can be acquired real-time, fast and synchronously .Different type contactors can be fixed fast and easily with the adjustable installation mechanism .The test system developed in the paper can improve efficiency and timeliness in the testing of dynamic characteristics of contactor greatly .%通过对接触器测试系统机械结构的设计，实现了激光位移传感器在三个维度内对测量目标快速锁定、切换以及接触器的快速省力安装，提高了接触器动态特性测量的效率。该系统包括可移动测试机构和可调式安装机构。所设计的可移动测试机构集成了各种动态特性参数测试所需要的模块以及可以实现在三维度内对测量目标进行锁定的三轴滑台，达到对接触器动态特性多路参数的实时、快速、同步的测量。所设计的可调式接触器安装机构可以实现不同型号接触器快速、省力的安装。整个测试系统可以显著提高接触器动态特性测试的效率和实时性。
