Abstract:

This paper describes the method of subjective evaluation and objective tests on impact shake when vehicle passing the typical speed bumper. By analyzing the impact hardness and impact shake response signal and further study on the the signal characteristics a Neural Network is setup to build the correlation between subjective rating and test results. The feasibility of this method applying on small sample group is also been studied.

摘要:

针对车辆行驶过程中常见的过减速坎的典型工况,描述进行主观评估和客观测量的基本方法,分析具有麦弗逊结构前悬车辆过坎冲击时振动响应的信号特征,探索利用神经网络直接建立主观评估和客观测量之间关联性的可行性,同时对小样本数据条件下如何更好建立合适的神经网络进行多种尝试,建立基于神经网络进行主客观评估结果关联性分析的基本方法。
