巴哈赛车制动连接件及制动器有限元分析

文章主要对巴哈赛车的制动器及其连接件进行有限元分析，运用UG 建模并导入到ANSYS Workbench 中对连接件进行结构静力学析，校核并优化连接件结构，主要处理方案：在应力集中的地方做肋板，并进行适当镂空；对制动盘进行模态分析，计算制动盘的固有频率，分析其振型，结果表明造成制动盘脱落的原因并非由制动盘与外界产生的共振扭断的，而是在行车时制动盘受到一个很大的轴向力，作用在连接制动盘的铆钉上，使铆钉失效而造成的。分析结果可以为赛车的连接件和制动盘设计提供参考。

FINITE ELEMENT ANALYSIS OF THE BAJA RACING CAR'S BRAKE AND CONNECTION PIECE

The finite element analysis of the Baja racing car's brake and its connection piece has been completed. The UG software is used to establish the connection piece 3D model, which is imported into ANSYS workbench to carry out its structural statics analysis, and the structure of the connection piece is checked and optimized. The main improvement scheme is to add ribs in places where stress concentration occurs and to hollow out properly. The modal analysis of the brake disc is carried out; the natural frequency of the brake disc is calculated, and the vibration mode is analyzed. The results show that the reason for the brake disc falling off is not the resonance torsion between the brake disc and the outside world, but the brake disc is subjected to a large axial force when driving, which acts on the rivet connecting the brake disc and causes the rivet to fail. The analysis results can provide reference for the design of the Baja racing car's brake and its connection piece.

Abstract: The finite element analysis of the Baja racing car's brake and its connection piece has been completed. The UG software is used to establish the connection piece 3D model, which is imported into ANSYS workbench to carry out its structural statics analysis, and the structure of the connection piece is checked and optimized. The main improvement scheme is to add ribs in places where stress concentration occurs and to hollow out properly. The modal analysis of the brake disc is carried out; the natural frequency of the brake disc is calculated, and the vibration mode is analyzed. The results show that the reason for the brake disc falling off is not the resonance torsion between the brake disc and the outside world, but the brake disc is subjected to a large axial force when driving, which acts on the rivet connecting the brake disc and causes the rivet to fail. The analysis results can provide reference for the design of the Baja racing car's brake and its connection piece.
