Vibration aging technology is often used to eliminate welding deformation and weld defects in the process of metal welding and manufacturing.It is an effective method to eliminate residual stress of casting or welding parts.The vibration aging treatment method is used to reduce and eliminate residual stress of all aluminum body welding structural parts of new energy vehicles,which can effectively avoid welding failure caused by welding deformation and weld defects,scrapping of car body.In this paper,a multi-dimensional vibration aging robot is designed,which can improve the automation of industrial production and deal with the residual stress of new energy vehicle structural parts and related castings efficiently.According to the structural characteristics of the suspension track multi-dimensional vibration aging robot and the requirements of the production process of new energy vehicles,this paper carries out the structural design and related theoretical analysis of the robot.The research contents are as follows:This paper introduces the research status of robot technology and multi-dimensional vibration aging technology,and uses TRIZ theory to analyze the system and cause and effect of existing vibration aging technology.It optimizes the mechanism configuration of the parallel manipulator of the vibration aging robot,and obtains the robot structure that meets the design requirements.Based on the topological structure design theory of the mechanism,the DOF of the parallel manipulator is calculated and simulated in multi-body dynamics The results show that the theoretical calculation is the same as the simulation results.The statics simulation and modal simulation of the multi-dimensional vibration aging robot are carried out by using ANSYS and ADAMS simulation software.The stress and deformation cloud chart,the first six modes and vibration modes of the robot are obtained.Through the simulation,the irrationality in the structure is found,the structural optimization of key parts is carried out,and the rationality of the design scheme is verified.The D-H parameter method is used to model the forward kinematics,and then the numerical method is used to solve the problem.The relationship between the length of the parallel manipulator and the change of the angle of the pose parameter of the platform is obtained by using MATLAB.The kinematics and dynamics simulation of the parallel manipulator is carried out in the multi-body dynamics simulation software ADAMS,and the position of the center of mass of the platform is obtained Comparing the curve with the result of kinematics simulation in ADAMS,the accuracy of theoretical calculation and simulation analysis is verified.In this paper,the workspace of the parallel manipulator of the multi-dimensional vibration time effect robot is analyzed,and the workspace of the parallel manipulator is obtained by MATLAB simulation,which provides the theoretical basis for the application of the robot.
