Optimization Design And Experimental Research On The Working Equipment Of Wheel Loader

The wheel loader to be used as a main engineering machine in national economy developments to develop to put great emphasis on to want the direct influence of good and bad of function, its function to produce the efficiency, service life and manipulate the function.The quality that the conduct and actions that work equip machine load its function of work organization is also directly work function that affected whole machine, whole machine of further influence of work efficiency, work device of the design level directly deciding lading machine of work function is with the market competition ability.Therefore, adoption forerunner of design method right load machine work equip proceeding analysis to study to become increasingly important.Before, the design fundamental of the work device up still compare the method along the type that use the tradition with make the diagram to try method, this kind of method to design the accuracy low, period long, not and easily acquire the satisfied design project.Despite at long-term of design inside backlog certain of design experience, but design still exsits bigger blindness.For look foring the satisfied project, usually complete the large quantity's dependence that handicraft painting work, and strong to kind machine, difficult then increase to design the quantity.Therefore, adoption forerunner of design method with design tool right work organization proceed design research the right and wrong is often necessary.Further for the traditional machine design, we only care about the static design of the frame. It makes the machine so ponderosity and not hard enough, and also the frame will be intervened. In this case, we not only waste our money and material, but also reduce our working efficiency. Now with the rapid development of computer, automatic dynamic analysis of mechanical and finite element will be used widely. Some dynamics analysis software of mechanical systems is also developed gradually and used in mechanical design. This can provide an more powerful way to dynamic design of the machine.Combine the traditional design theory with the modern design method and the working theory of the wheel loader-digger's working equipment. Find out the disciplinarian of the working equipment. Analyze the action of the working equipment, like the parallel remove and automatic flat down. Know the action of the unload angle and the drive angle. Study and compute the force of the bucket,the connecting of rod and rocker. Use ADAMS software optimizes the working equipment. Use the way of numerical value curvilinear to express the index of the translatableness and automatic flat down. It can give you an intuitionistic and real feeling.In the process of the dynamics analyze of the working equipment , use the software ADMAMS to simulate the system , Automatic dynamic analysis of mechanical includes mechanical system kinematics analysis and dynamics. The important part is analyzing the mechanism system kinematics and dynamics. Use computer assistant to analyze the technique , which can ascertain the position, velocity, acceleration of this system and all components at any time. We also make certain force and counterforce of the system and all parts by the way of solving algebra equation groups . We can obtain the graph of the change of the angle and the bucket in the progress of the working equipment moving . By researching of the change of the force , we obtain the force changing graph of the whole work progress which can provide the theory for the intension design of the moving arm.For insuring to analyze the accuracy of the result, the company is first to proceeds to kind machine the set experiment, then invited Peking to experiment the factory with the University of Shandong to successively can test to LG953 proceeding, then insure the LG953 batch quantity to throw the postnatal period and does not appear any quantity problem.To LG953 construction piece strength for press emulationing the work adding carry, acting 10 ten thousand times and behind examining the tired and expired circumstance of whole construction piece, then with emulation should working limited dollar of construction strength analysis proceeding contrasting, verifying the construction's piece.Combine then this guide 953 the design improvement of construction pieces.Pass the above treatise, and get the work superior project that equip and move the arm to best suffer the dint hour the construction shape.
