Chaos Identification of Two Rotational and One Translational Decoupled Parallel Mechanism Concerning Clearance
摘要
Abstract
CRRR proposed independently as research object,aiming at the clearances existing in the Hooke Taking a two rotational and one translational decoupled parallel mechanism PU-RCRR-joints,and combining Lankarani-Nikravesh contact force model and Newton-Euler method,the mech-anism dynamics model was established.The dynamic responses were analyzed,in addition,the chaos phenomenon contained in the mechanism was identified with Poincare map and the largest Lyapunov exponent.The results indicate that chaotic phenomena exists in the dynamic responses of the two ro-tational and one translational decoupled parallel mechanism concerning clearances.关键词
