摘　　要：介绍了硬度检测台的工作原理和特点,在UG3.0软件中完成设备的造型设计。针对检测台在检测过程中存在的碰撞问题,结合软件的运动分析与结构分析模块,对检测台底座进给速度问题进行仿真优化,并利用有限元分析功能对工件进行模态分析以及对探头连接处螺钉的强度进行校验,最后对整台设备的工作过程进行了运动仿真,实现了各系统间的协调运作。目前该检测台已投入使用并取得了良好的效果。Firstly, the working principle and characteristics about eddy current hardness testing device is presented, and the equipment＇s model is built based on the software of UG3.0. Then, by means of integrating the modules of UG/SCENARIO FOR STRUCTURES and UG/MOTION in order to deal with the problem of contacting when the device works. According to the data of simulation, the bed plate＇s feed velocity is designed and optimized. At the same time, the screw of probe＇s strength is verified and the simulation of the whole equipment＇s working state is described.Finally,the device has put into production and gained a nicer effect.
