Analysis And Study And Improved The Design Of The Steering System For The Medium Truck

In recent years, The continuous development of China's national economy,Continuous development of highway construction,Business of the logistics industry and to promote continued development and growth,Opportunity,Trucks of increased social ownership,Vehicle handling and stability become an important research topic,Automotive steering system as one of several important system,Its performance reflects the level of vehicle handling and stability,Therefore, the study how to improve the design of the existing truck's steering system has become an important issue。In this paper, medium-sized truck's steering system as the main object of study, Traditional steering system designed for the theoretical basis, Steering system has been improved on the design, And the introduction, proposed the theory of rectangular steering trapezoid. Modeling process in the use of ADAMS, Mechanical system dynamics based on the theory, Introduction, proposed a three-stage method modeling theory, The use of ADAMS / car module to establish a truck steering and front suspension system model, And a number of dimensions and model simulation analysis, Improved design verified the correctness of the theory. Verified by actual testing and comparative analysis, Verify the feasibility of improving the design; Validate the use of ADAMS / car modeling accuracy and feasibility analysis; Validate the use of steering trapezoid design of the feasibility of the theory of rectangular; Verify the three-stage method using theoretical modeling analysis of the feasibility of modeling. In the actual vehicle steering system to improve the design process, Medium-sized truck steering system for the design of new ideas and new methods were meaningful research and exploration.This paper studies the content can be summarized as points: After reading a lot of domestic and international literature on the steering system on the basis of, Brief overview of the steering system, And analyzed the development trend of steering system, That the focus of this study.A brief description of the mechanical system dynamics theory and basic composition of software modules ADAMSA brief overview of the basic theory of steering system design was writed, Introduced and made a turn to the theory of a rectangular trapezoid, In the process of modeling with ADAMS, Introduced and made a three-stage method modeling theory.The original design of the steering system and improved transformation system has been theoretically analyzed, Verify the feasibility of improved design, in theory, And with the ADAMS / car module to establish a truck steering and front suspension system modelUse the established steering and front suspension system model and improve the design of the original state of the state of simulation, Use of company's existing test equipment and means of experimental verification, Through the simulation results and comparative analysis of test results to verify the improved design of the feasibility of the use of models. The significance of this study the following aspects:To improve the actual model line system is designed to rely on the steering system in-depth analysis and research, design theory and practical application to improve the truck's steering system designed to effectively verify the feasibility of improving the design.By the actual vehicle steering system analysis and improved design is proposed based on traditional design theory steering power steering selection of new theories and ideas, and turned to the trapezoidal design of the new theories and ideas.Based on the actual model, Theory of steering trapezoid rectangular and the three-stage method of ADAMS model of the theory were Explored ande studied and researched, This is a meaningful ,It Provided a new design ideas and methods for The same industry, The results show that the research has applicability, research and promotional.
