Self-loading garbage truck lifting mechanism of the simulation and optimum design

In the modern automotive industry, CAD / CAE technology has been generally applied, China's auto companies are now widely used, such as CATIA / UG, etc. Set CAD / CAE / CAM software products in one design, the use of virtual prototyping instead of physicalinnovative design of the product prototype, test and evaluation, to shorten the development cycle, reduce costs, improve product design quality, enhance customer and market demand for the ability of other aspects of their role is increasingly apparent.In this paper, the object dump garbage truck, the use of virtual prototyping technology to CATIA / ADAMS software as a tool for loading and unloading in the white garbage truck's design and simulation analysis, to do the following: 1. Based on the design of dump truck process, carried out from the loading garbage truck dump bodies and parts design and calculation of the overall design, including the choice of chassis, subframe arrangement and form of lifting mechanism in the form and design, as well as the form and design of cars . 2. Based on three-dimensional design software, CATIA, constructed three-dimensional solid model of dump bodies, and through the virtual assembly, dump bodies to achieve the interference analysis. 3. Based on simulation software ADAMS, through the ADAMS interface with CATIA, CATIA built dump bodies will be three-dimensional solid model is imported into ADAMS, in the ADAMS system constraints to add, load, drive, and establishing a virtual prototype model and the dynamic Science simulation analysis, the dump body dynamics simulation results. 4. Based on finite element analysis software ANSYS Workbench key components of the finite element analysis, first created in CATIA solid model into one lift bearing, its mesh, defined by the loading conditions, finite element analysis, draw diagrams of their stress-strain and displacement, according to analyze the situation and then carry out the optimization of design work.
