摘要
车辆构件承载状况复杂,为保证安全使用,对其结构可靠性提出了较高要求。本文运用有限元分析软件ANSYS,采用蒙特卡罗和混合模拟两种方法分别对车辆构架可靠性进行分析、计算和比对。结果表明,混合模拟计算法具有较高的计算效率,可以满足车辆构架可靠性计算和模拟仿真需要。
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.
