Configuration Analyzing And Modern Designing Methods Of Steering-system Of Heavy-duty Vehicle

With rapid development of the national economy continuously in many years, the truck market develops fast. And the heavy-duty vehicle is the main direction of truck development. The heavy-duty vehicle has many strongpoints, such as high efficiency, low cost, and so on. So it gradually becomes the first choice of transportation. The production and research of the heavy-duty vehicle are competition focal point in domestic corporations.In this paper, taking heavy-duty vehicle as the research object, first introduced the type, composition and development of the automotive steering-system. Through analyzed the steering-system structure and appraised the steering performance, it has researched computational analysis methods of the steering-system kinematics character, suited computation methods of the power redirectors, computational analysis methods of movement coordination of the suspension system and the steering-system, and so on. It also introduced selecting methods of the power redirectors in the steering-system design. Moreover it also did the further research on the power redirectors matching and coordination problem of the suspension system and the steering-system, calculated steering wheel strength and momental gradient when the heavy-duty vehicle matched two kind of power redirectors, did entire vehicle performance simulation research on two matching schemes of the suspension system and the steering-system. Moreover this paper also introduced the character and function of ADAMS simulation software, summarized the rationale and process of the dynamics simulation analysis by using the ADAMS/Car module. And it established the whole steering-system model, did the kinematics, dynamics simulations on the steering-system, carried on preliminary appraisal in this simulations foundation. This topic research has provided a more scientific method for the design and development of the heavy-duty vehicle steering-system, improved the design quality, effectively shortened the research and development periods, reduced the development cost. It has explored the new way to enhanced the product design and the manufacture quality.
