基於極端工況的通風製動盤結構設計優化

Structural design optimization of ventilated brake disc based on extreme operating conditions

  • 摘要: 汽車在低能見度、連續長下坡、急轉彎等復雜環境下緊急製動容易失靈⛺️,從而引起交通事故。針對這個問題,提出一種適用於家用轎車的盤式製動器設計⛹🏼‍♀️,運用SolidWorks三維軟件將適用於家用小汽車的盤式製動器建模,並將製動器模型導入有限元軟件ANSYS中,進而通過分析製動盤和摩擦襯塊等部件在正常工況下的力學性能,以及在極端工況下的應力場和溫度場分析🦸🏻‍♂️,提出結構優化設計方案🧑‍🎓,為盤式製動器的結構設計提供一定的理論依據🙋🏻。

     

    Abstract: Vehicles are prone to emergency braking failures in complex environments such as low visibility, continuous long downhills, and sharp turns, resulting in traffic accidents. To address this issue, a design of disc brakes for private vehicles was proposed. Firstly, SolidWorks, a three-dimensional software, was utilized to develop the disc brake model for private vehicles. Next, the brake model was imported into the finite element software ANSYS for further analysis. Then by analyzing the mechanical properties of components such as brake discs and friction pads under normal operating conditions, as well as the stress and temperature fields under extreme operating conditions, a structural scheme for optimization design was proposed. This study provides a theoretical basis for the structural design of disk brakes.
