无论是有限元法还是系统动力学方法，都需要考虑滚珠丝杠的几何特征、材料参数、负载情况等因素，以便得到准确的振动模型, 2. 螺母：是一种与丝杆螺纹配合的零件，用于转动丝杆并将运动传递给机械结构,滚珠丝杠相反方向的运动也可以用于其他应用，例如在车辆制动系统中用于减速车轮, Abstract: This paper introduces a design scheme of ball screw lift. The lift is mainly composed of motor, ball screw, transmission shaft, guide rail and platform. Through the analysis of the kinematic principle of the lift, the parameters such as the power and speed of the motor, the specification of the ball screw, the material and size of the guide rail are determined. At the same time, the safety and stability of the lift are analyzed and optimized, ensuring the safety and stability of the lift. Finally, SolidWorks software is used for three-dimensional modeling and dynamic simulation analysis to verify the feasibility and superiority of the lift design. Keywords: ball screw, lift, kinematics, safety, stability, three-dimensional modeling, dynamic simulation analysis.,它可以提高生产效率和产品质量，减少人工操作和误差，实现自动化生产和智能制造,建议在下订单前与供应商确认交货周期, 3. 工作环境：在恶劣的工作环境中，需要选择更耐腐蚀、更耐磨损的材料,其主要特点是结构简单、升降平稳、操作方便、安全可靠,它具有精度高、速度快、运动平稳等特点，广泛应用于自动化生产设备中的定位、传送、夹紧、升降、翻转等控制系统中,这可以通过将滚珠从螺杆末端取出来，或者将螺杆两端的端盖拆开来，然后将滚珠取出来
