Study On The Design Method Of Machine Wheel Loader

The loader working device is composed of many parts，different series of theexistence of a large number of similar parts, they are just different parameters, but thefunction and shape did not change. The design of the traditions of the past, Whenchanging a parameter, you will need to modeling, If you generate similar to modelingwould no doubt spend designers a lot of time and energy. In order to save design time,improve design efficiency, In this paper, taking the wheel loader working device as theresearch object, with rapid and high quality design criteria, manufacturing for researchpurposes to study the load parameters for working device design with low cost.In this paper through in-depth study of the loader design knowledge, rod systemdesign. According to the law of motion of working device of loader working device, theestablishment of the hinged position. Stress analysis of the working device and stressanalysis and calculation on the arm, and rocker arm.Using Pro/E three-dimensional parameter software Parametric modeling of mainparts of machine loading device and the parametric model of the working deviceassembly. Through the movement simulation to check whether there is interferencecomponents. Describe whether correlation curve movement meets the designrequirements of inspection.Through the analysis of the demand and structure of the system and the idea ofparameterized design, Using two in developing the Pro/E powerful dispatched arm and arocker parametric design interface, The rapid design by changing the parameters of parts.Use of well-established loading machine working device model into the finiteelement static analysis of ANSYS,Finally the finite element stress nephogram, find thestress in the danger zone, By changing the design parameters to optimize the position ofstrength and stiffness. To reduce the stress concentration to reduce the damage tocomponents in practical application.This paper adopts the method of parametric design modernization, To improve thetraditional ways of design and improve the design efficiency greatly save design time,Has the guiding role for the product development of enterprises, To bring greatereconomic benefits to the enterprise.
