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, 代入数据，得到公称直径$d$为： $$ egin{aligned} d &= frac{2}{3} cdot frac{1000 ext{N}}{pi cdot 5 ext{mm} cdot cos 30^circ cdot 650 ext{MPa}} + 20 ext{mm} &= 26.2 ext{mm} end{aligned} $$ 接下来，需要计算滚珠丝杠的额定动载荷,其中，ISO1级的精度是最高的，误差范围在0.005毫米以内,滚珠丝杠上的螺栓是一种固定在滚珠丝杠上的螺纹连接件，通常用于将滚珠丝杠固定在机器或设备的底座上，以确保滚珠丝杠的稳定性和可靠性, 2. 调整预紧力: 如果预紧力不正确，需要调整预紧力
