Analysis of new-type 2-DOF space parallel mechanism based on screw theory
摘要
Abstract
The model of a 2-DOF 4R symmetrical parallel mechanism is studied.Based on the screw theory,the configuration is analyzed.At the same time,the motion screw system and the constraint screw of each chain are built.The freedom of the mechanism is calculated by using the revised Kutzbach-Grübler criterion.It is 2,which is consistent with the drive motor' s.The results provide a foundation to study this kind of mechanisms.关键词
