The Research Of Loading Machine’s Working Device And Hydraulic System Based On Cad/Cae/Cai Technology

In modern engineering construction, loading machine is one of the most widely-used shovel transport machines. The cycle of loading machines is operated through its movement, so that its design plays a key role in the whole machine design. The product of traditional working devices usually adopt analogy method to design which leads to less trivial work, lower accuracy of design and longer period of cycle. What is more, in order to finalize the design of products, it requires several rounds of repetition. Generally, it employs manual diagram or analytical method to analyze the structure of the working devices of the coupling loader. However, manual diagram results in lower accuracy while analytical method is complex and hard to comprehend the working performance and weight transformation. Therefore, it is vital and wise to choose modern design method to accurate the working devices.Having given parameters and settled conditions, the subjects of this thesis is to utilize the learned knowledge to decide the position of key ground point and to design the working device of reversal six-rod by using AutoCAD. It also includes using the three-dimension models creating by the software Pro/Engineer to assemble virtually and then analyzing and simulating in the kinematics-analyzing module of Pro/E to receive sound effects of simulation. Meanwhile, imported the analytical software ANSYS Workbench, it analyze the moving arm in finite element way to ensure displacement transformation and stress condition under the circumstance of joint shovel of moving arm so as to lay theoretical foundation of choosing and optimizing moving arm. Finally, by applying Flash, it is a vivid application because it simulates the hydraulic system of working device to provide reference to hydraulic system of loading machines. Through the simulation of kinematics, the finite element analyses and simulation animation of hydraulic system, it highly shortens the research and development cycle, boosts efficiency of design and improves the comprehensive performance of working mechanism.
