چکیده انگلیسی
The main purpose of this work is to present a comprehensive methodology to study the dynamic responses of multibody dynamics with revolute clearance joint, which is based on an improved nonlinear impact force model and a modified friction force model. A planer slider-crank mechanism with clearance joint between connecting rods and slider is used as an example. Firstly, the simulation models are presented which can take into account the influence of different clearance size, crank speed and material on dynamic responses of planar multibody systems. Secondly, an experimental test rig is designed, which can monitor the dynamic responses of the slider-crank mechanism by using a linear voltage differential transducer (LVDT) and an accelerometer. Then, the experimental tests are conducted, which have the same working conditions with numerical simulations, and the slider acceleration and FFT analysis of slider acceleration are presented as two measurements. Finally, the experimental and numerical results are compared and discussed, which validate the nonlinear impact force model in clearance joint, and the numerical results of dynamic responses of mechanism with clearance joint.
