Firstly, the structure and working principle of ball screw are introduced, and then the load and transmission characteristics of ball screw are analyzed. In view of the calculation problem of ball screw, a calculation method based on finite element analysis is proposed. By establishing the finite element model of ball screw and analyzing its mechanics, the stress and deformation of ball screw are obtained. Then, according to the calculation results, the design parameters of ball screw are determined, including the diameter of screw, pitch, diameter of ball, number of ball, etc. Finally, the correctness of the calculation results is verified by experiment. Keywords: ball screw; finite element analysis; design parameters; stress; deformation,当滚珠丝杠旋转时，滚珠会在螺纹上滚动，将旋转运动转换为线性运动，从而推动螺母沿着滚珠丝杠移动,它由一个固定的线圈和一个可移动的磁铁组成, 4. 长度：一般从200mm到6000mm不等，也可以根据客户的要求进行定制,可以根据不同的使用需求，选择不同的规格和型号的滚珠丝杠升降平台, 10. 日期标注：指定滚珠丝杠的生产日期，通常用数字表示，例如“2022.01.01”
