The development of electric vehicle manufacturing, which is considered a useful new popular propulsion system, has major design differences compared to conventional vehicles. This requires a reconsideration of the main components of vehicles and an analysis of them to determine the optimal design and solutions for the new models of cars. Among the many systems that need to be reconsidered is the suspension. A cheaper solution for reducing the car's vibrations is suspension where the damping is ensured by elastic rubber elements, which are very simple, as they have significant structural damping and a much lower price than the classic solution. The main advantage of this solution is the simplicity. The paper presents and analyzes such an element, analyzing the vibrations of this element and the way in which inertial masses (metal spheres) inserted into the volume of the rubber influence the behavior of this element. The transmissibility of such an element, and how the number of balls and the level of structural damping influences this property, is also analyzed. The results suggest possible applications in the automotive industry.
电动汽车制造的发展被认为是一种有用的新型流行推进系统，与传统车辆相比有重大的设计差异。这需要重新考虑车辆的主要部件，并对其进行分析，以确定新车型的最佳设计和解决方案。在众多需要重新考虑的系统中，悬架是其中之一。一种降低汽车振动的更便宜解决方案是采用由弹性橡胶元件确保阻尼的悬架，这种悬架非常简单，因为它们具有显著的结构阻尼，且价格比传统解决方案低得多。这种解决方案的主要优点是简单。本文介绍并分析了这样一个元件，分析了该元件的振动以及插入橡胶体积中的惯性质量（金属球）影响该元件行为的方式。还分析了这种元件的传递率，以及球的数量和结构阻尼水平如何影响这一特性。结果表明了在汽车工业中的可能应用。
