摘　　要： 为了考察动态作业过程中摩擦力、分离速度、环境温湿度和摩擦次数对静电电位的影响,解决传统测试仪器难以解决的"实时性"和"复杂性"等问题。通过模拟实验室方法,设计了基于虚拟仪器的静电电位测试系统。研究了不同物体材料在不同分离速度下的静电电位,通过分析来对比静电电位信号数据评估测试系统的性能:静电电位测试系统能稳定地长时间监控数据;测试系统测量精确,误差在3%以内;主软件程序需要的内存仅为507K;在实时监控静电电位方面具有较强的实用性。 In order to see about the effects of the rubbing power, the separating speed, the environment temperature, the environment humidity and the rubbing frequency to the electrostatic potentias, and to resolve the ＂realtime＂ and ＂complex＂ problems that traditional test equipment is difficult to resolve. The electrostatic potentials test system based on the virtual instrument is designed according to the simulation rooms . The electrostatic potentials of different material in different separating speed is studied, and the performance of this test system is evaluated by analyzing and comparing the experiment result. The result is that the electrostatic potentials test system canwatch system data for a long time steadily ; the test system has the error only under 3% ; the main software only needs 507K memory and can release memory in time, so the test system is propitious to the replanting and e tern; the test system has better practicability in watching electrostatic potentials in the real time nlarging of the sysenvironment.
