The main content of the design include : the design of the participation system , analysis of the structure pattern of the frame and suspension and determination of the main parameter , design of the structur eof the frame and suspension. During the entire design process , the principle s and the technical standard s are followed: the reasonable pattern and the size, the structure and arrangement ; the good smooth performance of the entire vehicle ; with reliable work, simple structure, loading and unloading, advantageous for the service and the adjustment; as far as possible general parts, in order to reduce the cost of the production , the function and the intensity request are guarantee d, the quality is reduce d as far as possible . The side frame and non- independent suspension are used quite widely on the low speed truck, because the side frame and non- independent suspension structure are simple, economical and practical, advantageous for the service and the refit . Considered the function of the frame and suspension in the entire vehicle design , first ly that the whole of the frame and suspension system is carried on design ing , then the structure of the frame and suspension h ave been carried on design ing , finally the stress generalized analysis of the structure of the frame and suspension has been carried on, their main parameter has been determined in the inferior foundation .
