| Abstract: | The complex situation of the vehicle component required a high structural reliability for ensuring the safe use.Based on the finite element analysis tool-software ANSYS,the paper chose the two methods-Monte Carlo and Hybrid to have an analysis and calculation for the reliability of the vehicle frame and have a comparative analysis for the results.The results showed that Hybrid method could meet the needs of reliability calculation and simulation of vehicle frame,and had a high computational efficiency. |
