| Abstract: |
| In order to study the dynamic behavior of a linkage mechanism with double clearances,we carried out simulation and experimental tests.For the simulation tests,we have built a nonlinear contact force model based on the software ADAMS.Meanwhile,an experimental set-up was designed and built to verify the simulation results.This paper mainly discussed the influence of the force on linkage mechanism in allusion to the different clearance size,loading frequency and loading force amplitude.The results show that,in the presence of clearance,the transfer force curves were influenced,and the clearance would make the linkage mechanism occur obviously vibration impact.The main factors that influence dynamic responses of a linkage mechanism are the clearance size and the loading velocity.The experiment results demonstrate validity of the model in this paper. |
