Structural Performance Analysis of Brake Pedal Assembly of a Commercial Vehicle
Based on the finite element method,a discretized model of a commercial vehicle brake pedal assembly is established,the corresponding boundary is loaded,and the stiffness simulation is carried out,and the analysis results show that its maximum deformation meets the design standard.The modal simulation results show that its first order frequency avoids the excitation frequency and meets the vibration requirements.Strength performance analysis results show that the maximum plastic strain is less than the engineering requirements,which can meet the practical use.By loading different loads and cycle times,the fatigue damage is less than 1,which meets the fatigue performance requirements.The analysis results can provide reference for the optimization research of brake pedal assembly.
