摘要： 从盘式制动器结构闭环耦合模型出发，应用最优化方法和静态加载模态试验，提取不同制动压力下的接触耦合刚度值，将实际工况的制动压力与参数模型的接触耦合刚度建立联系.随后运用灵敏度分析法探究接触耦合刚度对系统不稳定倾向的影响规律.最后利用接触耦合刚度与制动压力对应关系，将接触耦合刚度对制动系统不稳定倾向的影响转化为制动压力对高频制动尖叫的影响，获得使系统趋于不稳定的制动压力敏感范围，为高频制动尖叫的主动控制措施提供依据.

Abstract: Based on the closed-loop coupling modal of disc brake structures， an optimal method and static loaded modal test were used to extract the actual contact coupling stiffness with different brake pressures applied， and the connection between the brake pressures in the actual conditions and the contact coupling stiffness in the parametric model was established. Subsequently， the sensitivity analysis method was used to explore the effect of the contact coupling stiffness on the unstable tendency of the brake system. Finally， according to the corresponding relationship of brake pressures and contact coupling stiffness， the effect of contact coupling stiffness on the unstable tendency was transformed into the impact of the brake pressure on the high frequency braking squeal. The sensitive range of the brake pressure making the system tend to be unstable could be obtained， which is helpful to put forward the active control measures to suppress the high frequency braking squeal.

Key words: closed-loop coupling model, optimal method, static loaded modal test, contact coupling stiffness, brake pressure, high frequency braking squeal
