摘要
为准确测量气缸的实际摩擦力,本文建立了一个基于伺服电机速度控制的气缸摩擦力测试台,实现了测试过程中被测气缸运行速度和两腔压力的独立控制。系统采用多线程的流水线并行处理方式,在保证了采样数据完整性和操作实时性的同时,大大提高了系统的效率;同时系统实现了批处理测试的功能,从而简化测试操作,减少失误。实验表明,该测试平台测试方法合理,测试范围较广,测试精度和效率较高,操作和维护方便。
For the friction characteristics of pneumatic cylinders is one of the most important factors affecting the nonlinearity,an experimental apparatus was designed to assess the effect of a broad range of operating conditions,where the velocity and pressure of the cylinder chambers are controlled independendy.The system used Multithreading technology,greatly improving the efficiency of the system, and realized the batch testing function,which simplifies test operation and reduces errors.The experimental apparatus can be used to identify the friction model of cylinders,and will allow study of the effects on the friction force of different types of seal,lubricant,and cylinder barrel.
