摘　　要：制动器部件改进是直接消除制动器噪声倾向的一个明显消极对抗措施。这种把不稳定固有值变成复杂平面稳定部件的过程,要求采取非恒定转子系统的结构优化,但要一一精心研究Campbell图。如一个实际研究表明,对制动器摩擦衬块结构优化的前景和障碍关系到稳定固有值的指定和提供明确的公式,使其许可人们确定选择的耦合系统具有理想的稳定的和非稳定的模式。Structural modifications of the brake components is an evident passive counter-measure directed on elimination of propensity of the brake to a squeal. The assignment of the unstable eigenvalues into the stable part of the complex plane by the structural optimisation of the non-conservative rotor system re- quires, however, careful investigation of the doublets in the Campbell diagram. Such an investigation sub- stantially illuminates the perspectives and obstacles for the structural optimisation of brake pads with re- spect to stabilising eigenvalue assignment and provides explicit formulas, which allow one to assign desira- ble stable and unstable modes of the coupled system selectivly.
