9、,Parallel mechanism,点击添加文本,点击添加文本,点击添加文本,点击添加文本,Parallel mechanism,definition From a topological structure point of view, the robot is divided into parallel robot and Serial robot. Parallel mechanism is a closed loop mechanism. The moving platform or the end of the actuator by at least two independe

10、nt kinematic chains and the frame is connected, the essential elements are as follows: (1) the end effector must has freedom of movement; (2)The end actuator is connected by several interrelated kinematic chain or branch and the frame; (3)Each branch or chain by the only mobile pair or a rotational

11、drive pair.,点击添加文本,点击添加文本,点击添加文本,点击添加文本,The application of Parallel robot,In 1978, Hunt first proposed the six degrees of freedom parallel mechanism as the robot manipulator.In China, Huang Zhen who is a professor in Yanshan University , he developed the first six DOF parallel robot prototype in 199

12、1.Parallel robot is a new kind of robot. It has stiffness, bearing capacity of strong, small error, high precision, load / weight ratio is small, the power performance is good, easy control and other a series of advantages, will have broad prospects for development in the industry.The parallel robot

13、 has been used because of its advantages.Less degree of freedom parallel robot due to the driving part less, low cost, compact structure and high practical value, has a good application prospect, and therefore less degree of freedom parallel robot design theory research and application in the field

14、of development become parallel robot research one of the research hotspots.,点击添加文本,点击添加文本,点击添加文本,点击添加文本,Parallel mechanism,advantageThe advantages of the Parallel mechanism (robot) are as follows:(1) no accumulated error, high precision;(2) the driving device can be arranged on a fixed platform or n

15、ear a fixed platform, so that the moving part is light in weight, high in speed and good in dynamic response;(3) compact structure, high rigidity, large bearing capacity;(4) the fully symmetrical parallel mechanism has better isotropic;,点击添加文本,点击添加文本,点击添加文本,点击添加文本,Parallel mechanism,3 degree of freedom parallel robot,
