1、Name：夏永強(qiáng)（Sean）Magor：Mechanical EngineeringCONTENT點(diǎn)擊加標(biāo)題點(diǎn)擊加標(biāo)題The introduction of majorThe application of Parallel robotThe direction of researchParallel mechanismThe introduction of my major definitionMechanical engineering is an engineering discipline which involves the analysis, design, manufacture

2、and maintenance of mechanical systems using the laws of physics. Mechanical engineering is related to science and technology as the theoretical basis, combining the technical experience in the production practice, study and solve the application discipline in the development, design, manufacture, in

3、stallation, use and maintenance of machinery in all the theoretical and practical problems.ApplicaitionMachinery is the general name of the machine and mechanism. A machine is a tool that can help people to reduce their work difficulty or effort.Mechanical applications are needed by any modern indus

4、try and engineering field, There are more and more application of all kinds of machinery in our daily life, such as cars, bicycles, watches, cameras, washing machine, refrigerator, air conditionerand so on. Development prospect Mechanical engineering has always been to increase production, improve l

5、abor productivity, improve the economy of production, that is, to improve the interests of human beings as the goal to develop and develop new mechanical products. In the future, the development of new products will reduce the consumption of resources.The direction of research The direction of my re

6、search is Theory and Application of Robot Mechanism Topology . The systematic theory and method for topological structure synthesis of parallel mechanism has become a focus in the reserch field of mechanisms as a result of the increaseing application of parallel mechanism in motion ,robots ,parallel

7、 machine tools, simulators,micro manipulators and so on . Organization is the actuator and skeleton of the basic functions of the robot ,Mechanism is the robot to achieve a variety of sports and the completion of the main task of the specified task ,therefore Innovative design of robot mechanis is t

8、he core technology of robot technology innovation and development.Parallel mechanism Parallel mechanismdefinition 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 th

9、e actuator by at least two independent 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 t

10、he only mobile pair or a rotational drive pair. The application of Parallel robotIn 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

11、 in 1991.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 paralle

12、l robot 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

13、 field of development become parallel robot research one of the research hotspots.Parallel mechanismadvantageThe 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 near a fixed platform, so that the moving part is light in weight, high in speed and good in dy
