- Abstract:
- Based on the ADAMS ( Automatic Dynamic Analysis of Mechanical Systems) simulation softwareplatform, with the 3-RRR’T parallel mechanism as the research object and the Coulomb’s frietion into consid.eration, the contact force model of joint with clearance is established by using the nonlinear equivalent springdamp model. After simulating the model, comparing the dynamic characteristic of parallel mechanism which u.ses ideal joint use clearance joint, simultaneously comparing the dynamic characteristics of parallel mechanismwith clearance in one chain with that in three chains, we have the result that shows that the clearance affectsthe acceleration of moving, platform and mechanism’ contact force, so clearance should be considered whendesigning the mechanism.
