| 针对某SUV方向盘振动感知明显的问题,搭建了有限元模型,并运用模态分析和力传递率分析理论对压缩机所致方向盘的振动进行了仿真分析。根据仿真分析结果和客观测试结果对比分析,确定方向盘振感明显是由于压缩机隔振系统隔振效果不佳所致,并提出了压缩机隔振系统的优化方案。方案后客观测试压缩机运行时方向盘振动峰值降低了0.023g,降幅达到45%,且主观驾评方向盘基本无振感,表明本文所提将力传递率分析应用于压缩机隔振系统优化的可行性和准确性,为解决压缩机运行引起的方向盘振感明显的问题提供了一种切实可行的优化思路,拓展了力传递率的应用范围。 |

| Aiming at the problem of obvious vibration perception of the steering wheel of a certain SUV, a finite element model was established, and the simulation analysis of the vibration of the steering wheel caused by the compressor was carried out by using the theories of modal analysis and force transmissibility analysis. Through the comparative analysis of the simulation analysis results and the objective test results, it was determined that the obvious vibration feeling of the steering wheel was caused by the poor vibration isolation effect of the compressor vibration isolation system, and an optimization scheme for the compressor vibration isolation system was proposed. After implementing the scheme, the objective test shows that the vibration peak value of the steering wheel during the operation of the compressor is reduced by 0.023g, with a decrease rate of 45%. Moreover, in the subjective driving evaluation, there is basically no vibration feeling of the steering wheel. This indicates the feasibility and accuracy of applying the force transmissibility analysis to the optimization of the compressor vibration isolation system proposed in this paper. It provides a practical optimization idea for solving the problem of obvious vibration feeling of the steering wheel caused by the operation of the compressor and expands the application scope of the force transmissibility. |
