Title: Analysis and Optimization of Ball Screw Based on Finite Element Method
Abstract: Ball screw is widely used in various mechanical equipment due to its high precision, high efficiency, and low friction. However, the dynamic characteristics of the ball screw are complex and affected by many factors, including the preload, the lead angle, and the contact stiffness between the balls and the screw. In this paper, a finite element model of the ball screw is established to analyze the dynamic characteristics of the ball screw, and a multi-objective optimization method is proposed to optimize the design parameters of the ball screw.
The finite element model of the ball screw is established using the commercial software ANSYS. The contact between the balls and the screw is modeled using the surface-to-surface contact algorithm, and the preload is applied to the balls to simulate the actual working condition. The dynamic characteristics of the ball screw, including the natural frequency, the mode shape, and the stress distribution, are analyzed based on the finite element model.
To optimize the design parameters of the ball screw, a multi-objective optimization method based on the genetic algorithm is proposed. The design variables include the lead angle, the diameter of the screw, and the diameter of the balls. The objectives are to maximize the natural frequency and to minimize the stress concentration factor. The results show that the optimized ball screw can achieve a higher natural frequency and a lower stress concentration factor compared with the original design.
In conclusion, the finite element method is an effective tool to analyze the dynamic characteristics of the ball screw, and the multi-objective optimization method based on the genetic algorithm can effectively optimize the design parameters of the ball screw. The proposed method can provide guidance for the design and optimization of the ball screw in practical engineering applications.
