三平移并联茶叶筛分机机构设计及运动仿真
Mechanism design and kinematics simulation of three translation tea sieving machine
摘要
Abstract
In order to solve the problem of the multi-dimensional vibration that the traditional tea sieving machine cannot complete the multi-dimensional vibration, a new thought about multi-dimensional vibrating parallel mechanism tea sieving machine which could satisfy the needs of tea screening was proposed. Based on the parallel mechanism composition principles, the main body-mechanism of tea sieving machine was designed. This parallel mechanism contained three C-R-R chains which were vertical to each other in space. D-H matrix was applied to establish the kine-matical model, and the kinematical positive and inverse solutions were presented. The result showed .that the moving platform could get the ideal motion,and this parallel mechanism could be applied to the tea sieving machine. The virtual prototype of this mechanism was built by using Pro/E,and the model was added with kinematical pairs and imported to ADAMS software with Mech/Pro to complete kinematical simulation. The result of simulation proved the correction of the kinematical positive and inverse solution. Finally the test shows that the X,Y,Z three directions of vibration shorten the time through the sieve and can get the best sieving performance.关键词
