汽车的许多性能,如平顺性、操纵性、在不平路面上的平均车速与燃料经济性等,以及许多零部件的寿命都与由路面激起的振动有关。本文的主要目的是研究一种较全面的分析汽车承载系统的振动与动载荷的方法。近代动力学知识和汽车行驶路面的测量统计工作,使这种分析归结为寻求系统的各种频率特性。本文的主要内容是提供一种汽车振动与动载荷频率特性的分析计算法。这一方法使汽车振动与载荷的分析有较大的简化,然而它在原理上是“精确方法”而不是“近似方法”。因为
Many of the vehicle’s features, such as ride comfort, maneuverability, average speed and fuel economy on uneven roads, and many parts, are related to road-induced vibrations. The main purpose of this paper is to study a more comprehensive method to analyze the vibration and dynamic load of the vehicle bearing system. Modern kinetic knowledge and measurement of road traffic statistics work, so that this analysis boils down to the system to find a variety of frequency characteristics. The main content of this paper is to provide a method for the analysis and calculation of the frequency characteristics of vibration and dynamic load of automobiles. This method greatly simplifies the analysis of vehicle vibration and load, however, it is in principle an “exact method” rather than an “approximate method.” because
