Reliability Analysis Of Lifting Robot Based On Monte Carlo Method

Robot is a new technology in the field of automatic control.With the rapid development of industrial intelligence and automation,the application level of industrial manipulator has become one of the important symbols of contemporary enterprise production level.The use of robots instead of heavy labor on the workpiece handling and delivery work,not only achieve productivity improvement,and can greatly reduce production costs,while improving the production process of automation.At present,industrial robots are widely used in a variety of manufacturing,which plays a vital role,with the further improvement of science and technology and the rapid development of social production,industrial robot function and performance has also been further improved and Improve,so the role of industrial robots will be more and more,the application of more and more wide range.The reliability of motion is a new subject in the application of reliability technology in mechanical engineering.It is a new field of research which is different from strength or life reliability.It is the research institution under the stipulated use condition,the ability to complete the prescribed movement in an accurate,timely and coordinated manner.When using the probability to measure this ability,is the movement of reliability,it is a measure of various mechanical system movement quality is one of the important indicators.According to the reliability of the manipulator,the dynamic analysis of the manipulator is carried out,and the parametric simulation analysis is carried out under the joint action of the three hinges.At the same time,The use of Pro / E three-dimensional modeling to establish the solid model of tire unloading robot,through MATLAB programming to get two different tolerance with the next two conditions,And the parametric data of the solid model and the parameterized data are introduced into ADAMS for dynamic simulation analysis to obtain the movement curve of the tire removal robot during the movement process.And the position change data.Based on the Monte Carlo method,the reliability of the effect of the dumpling gap size and wear on the accuracy,speed and acceleration of the unloading robot is obtained by calculating the probability.The results show that the motion of the unloading robot(displacement,velocity and acceleration)of the unloading robot has a certain influence on the reliability of the unloading robot,and the size of the hinge gap has the greatest influence on the reliability of the unloading robot.The speed and acceleration of the robot are changed.With the constant movement,the hinge size of the tire dismantling robot will have a certain influence on the different wear stages during the movement.
