Abstract


The eccentric mass resonance fatigue vibration test machine is a test machine parts and structural fatigue life and fatigue characteristics of the testing machine, with a simple structure, easy to operate, high- efficiency , energy-intensive and low , can also be used to test various metal material anti- fatigue fracture properties . This topic is based on the finite element analysis software ANSYS10.0 existing structure of a dedicated auto parts eccentric mass resonance fatigue testing machine set up parameterized finite element model . Modeling process , reasonable simplified treatment of fatigue testing machine components . Convergence on the issue of convergence between the various components , respectively, using the direct coupling , the coupling spring unit connection as well as the spring unit is connected with the coupling combination . Modeled separately convergence parametric modeling in modeling the way , to take to overcome the difficult problem of complex structural modeling and modifying the finite element modeling process , in order to test the model correctness , at the same time in order to get fatigue the modal testing machine parameters , on the basis of the established finite element model of fatigue testing machine static analysis and modal analysis . Verify the accuracy of the model and coordination of fatigue testing machine would order natural frequency and vibration mode , and made the necessary preparations for the subsequent dynamic response analysis . In order to investigate the quality of fatigue testing machine counterweight , excitation frequency and the stiffness of the test piece and the relationship of the force of being tested , the use of the finite element model of the machine parameters dynamic response analysis . Respectively obtained tendency and degree of the mass of the counterweight of the fatigue testing machine , the excitation frequency and the stiffness of the specimen , and other parameters on the response to the test piece by force , to obtain a variety of different operating conditions of the tested items force specific values ??and corresponding to the response curve . Finally, on the basis of the results of the finite element output , using Matlab software fitting the corresponding response curve to obtain the mass of the counterweight , excitation frequency , the stiffness of the member to be tested with the specific relationship of the force to the test piece . Work fatigue testing machine engineering staff to provide the design basis for the operator to provide a reliable data transformation and serialization products , but also provides the necessary reference .
