Research of Shift Quality Evaluation Based on Random Receptor Spectrum

摘要

In order to accurately evaluate the vehicle shift quality, the response model of the shifting process to the complex random uman body is established. The random vector composed of the human body model parameters corresponds to the random human body, and the distribution of the human is represented by the probability density of the human body model parameters. The concept of stochastic receptor response spectrum was introduced from the seismic response spectrum. The stochastic receptor response spectrum of the evaluation index with the parameters of the human body model was calculated and simulated for the known shift process. Based on the random receptor response spectrum, the research on the acceleration and annoyance rate was introduced. The shift quality was evaluated from single index and multiple indicators. The evaluation results reflected the feelings of all possible people on the shifting process and the distribution of people. It has solved the problem that the previous shift quality evaluation can not evaluate the random human body's feelings about the shifting process. This study provides a theoretical basis for the quality evaluation of shifting machinery for mobile machinery.
