Crawler Irrigation And Drainage Cab Design And Topology Optimization

The main purpose of developing the machine of irrigation and drainage crawler is to increase the level of emergency irrigation and drainage facilities, and enhance emergency response capability for emergency drainage and irrigation. It is not only moving on the complex roads and short time of setting up and adjustment, but also integrating the drainage pumps,drives and running gear in one structure, as well as reducing the demand for operating workers.This dissertation combines Key Project (Project No. :2130317) of Water Resources Department in Jiangsu Province -- the development of irrigation and drainage crawler. Studying and Discussing the man-machine interface design on the irrigation and drainage crawler' cab , and providing a preliminary theoretical basis and relevant data for the cab design by using the finite element method and topology optimization which for the structural analysis and optimization.Through the research of the design situation and analysis about engineering truck's cab at home and abroad put forward the overall design plan of the driver's cab combined with the characteristics of the crawler type irrigation car. By means of CatiaV5r17 to carry through the modeling and design of the overall structure, at the same time finish the geometric model.And designed the driver's seat, instrument panel, oval eyes and other aspects by using man-machine engineering,as well as building the geometric model of the cab in CatiaV5r17.Then it did the structural analysis by using the finite element method and discussed the simplified principles of the finite element model,calculated the displacement and stress distribution in two working conditions of the reverse and the bending and as well as the modal analysis, and obtained natural frequencies and corresponding the vibration mode, so as to provide a theoretical basis for restructuring.At last came to the conclusion by comparing the results of two single condition on the topology optimization and topology optimization under multiple loading conditions; then got the optimization of the reinforcement layout by the distribution of the material under multiple loading conditions,exported the results by OSSmooth in Hyperworks9.0 and saw the visual results in CatiaV5r17,and it have been trimmed before in the calculation and analysis under the same conditions to illustrate that this design method not only has good applicability and practical ability, but also proved that the method of topology optimization has a very broad application prospects on the motor vehicles and related parts of the design process.
