摘　　要：介绍了滚珠丝杠轴向静刚度试验台机械结构及原理,设计了其防转结构和位移传感器工装。分别考虑滚珠丝杠副绕x轴的转动量和绕y轴的转动量对位移数值的影响,对3个位移传感器的示数通过运算转换成了中心点的位移,提高了最终刚度值的测量精度。最后对该工装和算法进行了试验验证,证明了该方法的可行性。This paper introduces the mechanical structure and principle of the ball screw of axial static stiffness test rig and designs its anti-rotating structure and displacement sensor tooling. It also considers the influence of corresponding changes of ball screw assembly around the x axis and y axis on the displacement value,so that the three displacement sensor readings are calculated,and then changed into the center displacement,in order to improve the measuring accuracy of the final stiffness valu,and effectively proves the feasibility of this method through testing for tooling and algorithm.
