- Abstract:
- In order to design a simple and reliable lifting hydro-cylinder bracket structure, the topology optimi-zation mathematical model based on the Variable Density Method was established by the volume fraction as constraint conditions and the weighted compliance as objective function. By means of linear approximation method, analyzed the force condition of the lifting hydro-cylinder bracket of a road sweeper with composite trash bin in the dumping process and determined lifting starting condition and maintenance condition as the main force conditions for the design of the lifting hydro-cylinder bracket. The topology optimization design of the lifting hydro-cylinder bracket was carried out by using the Variable Density Method. Considering the relia-bility of manufacturing process, a three dimensional model of the lifting hydro-cylinder bracket was established based on the topology optimization results, and the linear static analysis of the model was carried out. The final results showed that the lifting hydro-cylinder bracket designed by the variable density method had the advanta-ges of simple structure, small occupied space, the largest stress and maximum strain in reasonable range and met the requirements of the application.
