1. 研究目的与意义（文献综述）

leaf spring suspension is a kind of vehicle parts, with simple structure, low cost and reliable operation. leaf spring suspension can be divided into multi leaf spring and few leaf spring suspension. among them, the multi leaf spring suspension is simple in structure, low in cost, reliable in operation and suitable for heavy-duty vehicles. the front suspension of the less leaf spring suspension adopts the less leaf spring, which has the characteristics of equal stress and small friction between the sheets, reduces the mass of the whole vehicle, meets the trend of vehicle lightweight, improves the smoothness of the whole vehicle and the comfort of the driver, reduces the noise, and is suitable for the light load vehicle.

adams, automatic dynamic analysis of mechanical systems, is a virtual prototype analysis software developed by american mechanical power company. the simulation of adams software can be used to predict the performance, motion range, collision detection, peak load and calculate the input load of finite element. on the one hand, adams is the application software of virtual prototype analysis, on the other hand, it is also the development tool of virtual prototype analysis.

using software to design steel plate suspension system, and using adams to simulate, calculate and simulate it, on the one hand, the result is accurate, easy to control and predict, on the other hand, it avoids the complexity and high cost of vehicle experiment, which has great engineering value and academic research significance.

2. 研究的基本内容与方案

according to the automobile theory and automobile design knowledge, the leaf spring suspension system of a passenger car is designed. the design process is programmed and solidified by computer language to form a complete set of software package with good human-computer interface. the specific plan includes three stages:

the first stage is the design of the leaf spring suspension system. through calculation, the system parameters, such as the hard point coordinate of the suspension mechanism, the spring stiffness and the damper damping, are obtained;
