Abstract


Currently, the as forging national industrial development and the increase in demand for large forgings , forged increasingly large load capacity and load torque required by the operating machine , the kinetic properties are becoming increasingly complex , a variety of factors in the performance of the institutions operating the influence gradually increasing , so consider a variety of factors, such as hinge friction , gap giant overloaded operators clamping mechanism kinetic study has important theoretical significance and value of the works . This paper aims to take advantage of an easy- hinge nonlinear factors modeling method . To do this , first of all , for the institutions in the prevalence of dry friction characteristics of the gap , with open key GRAPH METHOD its kinetic model were established ; Secondly, dry friction and clearance for institutional hinge exist simultaneously modeling calculation comparing complex , use the key to open the Figure establishing of a non-linear model of the hinge , and clamping mechanism vector bond graph modeling embedded in a modular form which gives the clamping mechanism to consider the non-linear factors mixed key bond Graph model, obtained by simulation of nonlinear factors impact on the dynamic performance of the clamping mechanism ; Finally, pluripotent domain similarity theory as a guide to a strictly figurative power bond Pictured tool to establish the reaction clamping the test model similar to the electrical system of the organization , from the trial level to further explore the characteristics of the clamping mechanism , consider the nonlinear factors clamping mechanism to verify the correctness and reliability of the hybrid bond graph model .
