基于等价路面粗糙度的汽车建模方法的研究

至今,关于路面噪声评估技术已有一些报道.虽然仿真输入的表达方式很重要,然而它们定量分析不足,因为路面输入形式非常复杂.文中,首先定义了一个新函数--等价路面粗糙度,这样模型得到了简化,然后将这个函数应用到一个实际系统中,最后通过使用该函数来评估悬架的内部噪声和振动,并通过比较实验数据和计算数据来验证这种方法的正确性.

Study on the Automodbile Modeling Method of the Input Form for Equivalent Road Roughness

Some papers concerning the estimation technology for road moist have been proposed so far They however are not sufficient quantitatively because the input form from road's surface is very complicated,althouth it is important how the input on the simulation is expressed .In this paper, first of all, a new function, 'equivalent road roughness' is defined and proposed for a simplified model ,And then, this function is generalized to an actual system .Finally, the internal noise and the vibration on a suspension are estimated by using the proposed function and is verified comparing the calculating data and the experimental one.
