Abstract


With the rapid development of China's automobile industry and computer technology continues to improve , computer-aided engineering technology because of its combination of various advanced methods and technologies, and to improve product quality , shorten product development cycles and reduce costs so significant effect , while in widely used in the automotive industry . For a certain type of truck is put into use and the resulting damage to lifting mechanism subframe weld fracture problem, we set the virtual prototype and finite element techniques for lifting mechanism and the sub-frame and structural stress analysis optimized to improve lift capacity , reducing the stress weak parts . This paper uses software to build truck lifting mechanism ADAMS virtual prototype , its dynamics simulation analysis , and optimization of the position lifting mechanism , improve lifting capacity ; subframe with ANSYS software for three-dimensional modeling of the lifting conditions imposed loads and constraints are discussed , and the sub-frame for static and dynamic analysis . Finally, according to the actual need to set the design variables , state variables and the objective function for the sub- frame structure optimization . In this paper, Virtual Prototyping in the design of the lifting mechanisms in all aspects of the process of developing a detailed discussion of the role and use of finite element techniques to analyze and optimize the sub-frame , with a strong academic value and engineering practice significance.
