摘要
对机床导轨爬行现象的机理进行了理论分析,并在理论分析的基础上建立起简化的二元摩擦振子物理模型,根据该物理模型推导出由影响爬行现象的各主要参数表示的数学模型。通过ADAMS软件的运动学仿真,对数学模型中的各个参数进行调试,验证了各主要参数之间的相互影响关系。通过比较影响机床爬行的各个参数方案,获得最佳结果。
The crawling phenomenon of machine tool is theoretically analyzed, and a simplified physical model of binary Iriction oscillator on the basis of theoretical analysis is set up. Based on the physical model, the mathematical model with the main parameters of crawling phenomenon is built. Through the dynamic simulation by ADAMS, the various parameters of the mathematical modal are debugged, the interaction relationship of the main parameters in the crawling phenomenon is found. By comparing the influence of all parameter schemes on the machine tool motion, the best one is got.
