Abstract:

Finite element model of band brake transient temperature field is built considering heat transmission theory and drum brake structural features. The randomness of physical parameters and boundary conditions of heat transfer was considered, each parameter and initial boundary conditions are regarded as interval parameters. With the finite element and time difference methods, the perturbation formulas of the upper and lower bounds of responses of temperature fields with unknown-but-bounded parameters were derived via the combination of interval analysis and the traditional finite element method. and then the range of temperature field response of the drum brake is obtained. The results show the method of the paper is feasibility and effectiveness
