The Development Of Truck Lifting Mechanism Optimization Design Platform Based On Whole Truck

This paper regards actual demand of enterprise as the starting point and regards the second-development of truck lifting mechanism optimization design platform based on whole model as the research object, researched the whole process of platform. The platform changed hydraulic pressure lifting mechanism design method, rapidly, efficiency, quality assurance. The platforms for six kinds of lifting mechanism familiar in China are developed and established, and the hinged points of the six kinds are arranged with ADAMS software.Firstly, this paper describes the current domestic and foreign situation of researching in truck lifting mechanism, connect the project requirements, regards the flow (path) of software second development as bus, overall analysis demand of enterprise, and confirms design demand, function demand, theory demand and other demand of the platform. Designs dataflow of platform in function level and carries on detailed research to the data in the operation course of the platform at the same time. Subsequently, the paper stands the global point to carry on detail research to the overall design process. In process, confirms the development way of the platform at first. Then designs system architecture, basic functions model and makes a concrete analysis to the function module, provides the operation procedure of platform.Researching the platform of truck lifting mechanism optimization design based on whole mode must be have the whole parameterized truck model and lifting mechanism's mathematical model for optimization, so the paper dentally research the truck chassis parameterized and lifting mechanism (carriage) parameterized, and confirms all kinds of design variable, constraint condition, optimization object.Afterwards, the paper researches how to design the platform concrete, designs the menu, dialog and function modules, and provides the realization codes of automatic build the whole truck model and simulation control to satisfaction of customer demanding. After several experiment, the result indicates that the platform runs steadily, its can quickly finish the lifting mechanism design. Finally, the typical truck is simulated, analyzed and optimization designed with the developed platform. By means of which the curves displaying thrust changing separated from static and dynamic simulation on whole model, it's found that the maximum dynamic thrust is 10%-15% more than the static's while the lifting mechanism being normal. At the same time, two different optimization designs about lifting mechanism are carried out. The maximum thrust is induced by 20.68% compared to the initial condition with all the joints being considered, when the maximum thrust is only induced by 12.41% compared to the initial condition while without changing the triangular shape.The research of this paper has not merely offered an advanced tool for enterprise, solved the problem of enterprise, at the some time, it provides a good reference to solve the similar problem.
