Although disc brakes equip mass produced vehicles, drum brakes are still applied on medium and heavy duty vehicles. However, both exhibit high level of brake noises which the squeal is the most uncomfortable and one of the reasons behind high warranty costs. Hence the brake noise prediction method has prompted significant efforts to develop numerical models using the finite element method. This intends to analyse design parameters of a heavy duty automotive drum brake using its parametric finite element model composed by drum, shoes and frictional linings. Moreover, it is conducted static calculations to get a pre-stress state around which is computed the complex eigenvalues. At the end is presented the best material parameters to obtain low squeal occurrence.

虽然盘式制动器装备在批量生产的车辆上，但鼓式制动器仍然用于中重型车辆。然而，两者都表现出高水平的制动噪音，其中尖叫声是最不舒服的，也是高保修成本的原因之一。因此，制动噪声预测方法促使人们大力努力开发使用有限元方法的数值模型。本文旨在使用由鼓、蹄片和摩擦片组成的参数化有限元模型分析重型汽车鼓式制动器的设计参数。此外，进行静态计算以获得预应力状态，围绕该状态计算复特征值。最后给出了获得低尖叫声的最佳材料参数。
