针对机床滚珠直线导轨副工作时铣削力作用产生的精度衰退现象，以滚珠直线导轨副中滑块受力规律为研究重点，利用SolidWorks建立滚珠直线导轨副与平台安装简化模型。应用RecurDyn进行多体动力学仿真，得到滑块垂直方向受力随时间的变化规律。将滚珠直线导轨副滑块负载理论公式计算绘制的受力曲线与仿真所得受力曲线对比分析，验证了模型简化及仿真方法的合理性与可行性，为试验平台载荷的施加及测量提供一定的依据。

For reseraching the phenomenon of accuracy recession in the practical work,the linear ball guide and its simplified platform model were built on SolidWorks to focus on sliding block’ s loading law. The re-cular of the slider vertical force changing with time was get through the Muti-body danamic simulation by RecurDyn. It is concluded that the simulation method is proved rationality and feasibility by Comparing the simulation force curve with the loading force curve which were calculated using a formula theory of linear ball guide,and measurement of exerting load test platform provides a certain basis.
