摘要
针对汽车盘式制动器在制动过程中会产生大量的热及制动时会发出噪声等问题,对制动盘进行有限元分析与优化。在SolidWorks中建立简化后的盘式制动器的三维模型,导入至ANSYS中添加约束及载荷,进行静力学与模态分析,得到制动盘和摩擦片的应力集中区域和可能产生共振的频率范围。对制动盘结构进行优化,并对优化后模型进行模态分析,验证了优化结果的正确性,为盘式制动器的结构设计提供了一种思路。
In order to solve the problems of a large amount of heat and noise in the braking process of automobile disc brake,the structure design and optimization of brake disc are carried out.The simplified three-dimensional model of disc brake is established in SolidWorks and imported into ANSYS to add constraints and boundary conditions for static analysis and modal analysis.The stress concentration area and possible resonance area of brake disc and friction plate are obtained.The structural optimization design of the brake disc is carried out,and then the modal analysis is carried out to verify the optimization results,which provides an idea for the structural design of the disc brake.
