This paper introduces the trailer hydraulic steering system of module combination subject background, combined with the development trend and trailer combination entrusted with the actual requirements of the project, explained the necessity of this research, and study the main purpose and meaning. In the detailed analysis of the status of the vehicle steering mechanism on the basis of domestic and foreign, considering the specific requirements of enterprises, determine the main contents of this paper. This paper analyzes the combination of hydraulic modular trailer the overall structure and main technical features of the splicing trailer introduces the combination of form and focuses on the structure of its steering system characteristics, including analysis of steering, steering implementations introduced center to board and steering Festival board structure characteristics, and truss layout and circuit connectivity patterns of change. According to business users after the query module for the request, the query module needs analysis, while the overall structure of the query module the analysis and development platform, the preparation of the final design out of a combination of user-oriented query module trailer. Then, this analysis of the combination of all-wheel trailer and the actual rotation angle theory formulas and procedures for implementation, the actual angle in solving formula, the proposed "three-link decomposition method" and analyzed and discussed the "three-link decomposition method "computing principle, application methods and procedures to achieve by using the" three-link decomposition method "on the combination of trailer wheel rotation relationship of the actual calculation methods are analyzed, the preparation of the computer program, and the actual vehicle, for example, use computer program the actual relationship between the wheel angle is calculated. Then, this article focuses on the combination of trailer steering mechanism of the optimal design. Optimal Design of steering mechanism were analyzed to derive an improved mathematical model of optimal design and programming. After the actual vehicle, for example, use of programmed cycle of combination trailer steering mechanism under splicing are optimized, the optimized objective function value decreased compared with 39.3% before optimization, optimization achieved very good results. Finally, according to business requirements, the use of optimization procedures derived, hybrid programming approach to the preparation of a combination of a hydraulic trailer steering mechanism optimization design module. Through this combination of trailer steering mechanism of the study design for the enterprise provide a good reference for enterprises to solve practical problems. Meanwhile, this paper optimal design of steering mechanism, providing a quick calculation tool used to improve the design efficiency, but also provide theoretical support. This study on the combination of trailers similar study provides new methods and ideas, has a practical significance and research value.
Key words: combination trailer spliced form of optimal design steering angle calculation
