A reliability sensitivity analysis based on modal stress is presented and applied to predict the influence factors of parameters on drum brake. Firstly, the first 10 modes of prestress of the brake drum are performed in the software ANSYS Workbench. According to the results of brake noise research, it can be detected whether the drum brake meets the results that the noise frequency range of 500-1 000 Hz. The reliability sensitivity design of mechanical parts based on the normal distribution parameters for complex mechanical system is discussed. Secondly, according to the first order second moment(FOSM) theory on reliability, the reliability sensitivity of drum brake is analyzed and calculated, and compared with the Monte Carlo(MC) numerical simulation results, The variation rules of reliability sensitivity is given, which provides a theoretical basis for the design of drum brake.
Key words:    modal stress    drum brake    reliability sensitivity    first order second moment    Monte Carlo
