摘要:
以某款轿车为研究对象,建立12自由度汽车乘坐动力学模型,通过达朗贝尔原理推导动力学方程.首先,采用滤波白噪声法建立路面不平度时域模型,生成的C级路面随机激励高程变化在-0.05~0.05 m范围以内,符合实际路面.然后,在Simulink中建立人-车-路系统仿真模型,对轿车在不同车速下不同位置的人体振动响应进行仿真分析,并进行舒适性评价.最后,进行实车试验,验证模型的正确性.结果表明:在50 km·h-1车速下,所有乘员的主观感受为稍有不舒适;随着车速的增加,前排乘客和驾驶员稍有不舒适的主观感受越来越强,而后排乘客的主观感受由稍有不舒适增加到有些不舒适.
Abstract:
In this work, a 12 degree of freedom(DOF)riding dynamics model for automobile is established for a(XX type)car. The dynamics equations of the model are derived by using D’Alembert principle. The white noise filtering method is applied to establish the time domain model for road roughness. The generated C level road surface random excitation displacements are within the range form -0.05 to 0.05 m, which is in consistent with actual pavement. Based on the human-vehicle-road system simulation model established in Simulink software, the simulation and analysis of human vibration response in vehicle at different speeds are carried out and riding comfort is evaluated for each human body. Finally, the real vehicle test is carried out to verify the correctness of the model. The result shows that all people feel slightly uncomfortable at a speed of 50 km·h-1. As speed increases, the feelings of front passenger and the driver are getting stronger, the rear passengers feel a certain degree of discomfort.
