直线滚动导轨是数控机床的重要功能部件，对导轨系统进行解析建模可以有效分析导轨的特性参数对导轨力学性能的影响。该文基于Hertz接触原理，对直线滚动导轨进行了Hertz接触建模及接触刚度求解。首先，推导了导轨系统中单个滚珠-沟槽的接触刚度解析表达式。在此基础上，系统地分析了滑块与导轨之间的变形关系，完成了整个导轨的法向接触建模。最后，以NSK直线导轨为对象，分别求解了单个滚珠及4种预紧力等级作用下整...

As many philosophers of science have pointed out, the reliability of the phenomena we test our theories against is pivotal (Bogen and Woodward, Galison, Mayo, Franklin). If our experimental evidence i...
