- 在这项工作中，通过取代传统的固体辐条与胶体辐条，一个内置的悬架结构的车轮提出。首先，在介绍车轮系统的背景和描述的基础上，提出了一种胶体轮辐车轮的振动模型，并在此基础上辨识了等效阻尼系数和弹簧常数。在此基础上，提出了一种修正的四分之一车辆在粗糙路面上行驶的模型，以估计路面不平度对车身的振动传递率。最后，以振动传递率最小为目标，确定了最佳的胶条设计和胶条数量，以使车辆的乘坐舒适性最大化。
— In this work, by replacing the traditional solid spokes with colloidal spokes, a vehicle wheel with a built-in suspension structure is proposed. Following the background and description of the wheel system, firstly, a vibration model of the wheel equipped with colloidal spokes is proposed, and based on such model the equivalent damping coefficients and spring constants are identified. Then, a modified model of a quarter-vehicle moving on a rough pavement is proposed in order to estimate the transmissibility of vibration from the road roughness to vehicle body. In the end, the optimal design of the colloidal spokes and the optimum number of colloidal spokes are decided in order to minimize the transmissibility of vibration, i.e., to maximize the ride comfort of the vehicle.
