Finite Element Analysis And Optimization Of Gondola's Telescopic Boom

As the gondola been widely used , and the structure's reliability, safety and economy have also received more and more attention. The structure of simulation and finite element analysis is the main methods to test its reliability and safety, and to optimize the design of the structure is the main methods to improve gondola's economic, save material and the cost of it's manufacture.Based on the basic theory of the finite element and structural analysis , This paper chooses gondola's main force structure - telescopic boom as the main study aim, carried out a series of studies. First, large-scale computer-aided design software Pro / E has used to design its parametric model, the welding module of Pro / E will telescopic boom between the various parts of the welding information into the parameters of the whole Model. Secondly, analysed the gondola's conditions and its mechanical character, and choosed two dangerous conditions of telescopic arm , on the basis of this, a large-scale finite element analysis software ANSYS has been used to analyse the two dangerous condition, the reliability and safety of the verification and analysis of a constant speed and the the stress and strain's condition when sudden braking, and found that the design of the arm is too conservative, not only to ensure the normal and stable Work, but there is still much room for optimization. Finally, use the OPT optimize design module of ANASYS ,the author choose the wide,the height and the thickness of the arm as design variables, the smallest volume as a goal, optimize the boom on structural and obtain the optimize results.
