The Caculation Of The Structure Loads, Finite Element Analysis And Optimization Of The Front Frame Of CLG856 Wheel Loader

As a vital member of the project, the author has done the calculation of the loads applied on the front frame of the loader and the project of application of finite element analysis and optimization in engineering. This paper is based on the project.Loader is a kind of construction machinery widely used in many fields such as architecture, traffic, power station, mine, national defense and so on. It plays an important role in accelerating the speed of engineering construction, alleviating the labor intensity, improving the engineering quality and reducing the engineering costs.The front frame is a pivotal part of loader which connects the back frame, the front axle and the work installment. The designing level of the front frame affects capability of the front frame and then the loader such as strength, stiffness, reliability, economy and so on. Finite element analysis and optimization are modern design methods; the stress and strain of the front frame in each work condition are obtained by the finite element analysis of the front...
