Drum Brake And Vibration Noise Study Based On ANSYS

The Chinese Automobile Industry has made tremendous progress and played an important role in the growing economy. Meanwhile, customer's expectation on safety and comfort are rapidly catching the world class level. Vehicle noise, in particular the brake noise has increasingly attracted widespread attention of customer's. The study of the mechanism of brake noise and the reduce noise are essential.Brake noise hazards are mainly manifested in the following aspects:1. Community environment noise makes community residents'complaint;2. Influence driving comfort and cause customer dissatisfaction;3. Influence resources input of the design and manufacture of drum brake assembly;4. Influence suppliers'product development of drum brake assembly;5. Influence the sale of automobile plants. So, finding the root cause of brake noise and designing a kind of low-noise drum brake assembly, whether from reducing noise pollution, meeting customers'demands and improving product development of drum brake assembly or raising the sales level of automobile plants are very meaningful.Disk brakes and drum brakes are two major types of brakes. Drum brakes is widely used in large and medium-sized bus and truck because of their compact structure, reliable performance, high braking power and low cost. In this paper, drum brake noise study is conducted through finite element analysis. The noise fix solution is validated with successful results.First, a summery of previous study on brake noise is presented to focusing on...
