The Structure Optimization And Vibration Control Of Injection Robot

With the vigorous development of the modern injection molding industry, injection molding design and improvement of the manipulator attracts more attentions.This paper realizes the manipulator parameterized modeling of main components by SolidWorks API functions. The manipulator model was putted into finite element analysis software ANSYS and the numerical simulation analysis was carried out. The typical working conditions of the manipulator was simulated and the static and dynamic characteristics of the manipulator. Observing the results of the analysis, the base nd the main arm beam of the manipulator are moving material, realizing the lightweight design of the manipulator.Selecting two propotion from the base and the main arm beam respectively for topology optimization, Two proportion of topology cloud of injection base beam and the main arm of the manipulator were integrated, material was removed by digging a hole to to reduce the weight of the manipulator. ANSYS topology is in a static environment with the aim to optimize structural flexibility, and only show the approximate location of a removing material, the location and size to remove can’t be sure. This article adopts the method of multi-objective size optimization determineing the location of the removal part and dimension, realizing the lightweight design of the manipulator, and to ensure the dynamic characteristics of the manipulator. This method of topology optimization combined with size optimization provides an effective method of mechanical handle gently, verified in this paper, can be used in the design of other products.In order to reduce vibration in the process of the manipulator and improve the positioning precision of the manipulator, the vibration control technology is studied in this paper. According to the condition of mechanical vibration, a kind of simple and practical quality of spring damper was designed, and the shock absorber’s damping effect is verified after appliying to injection manipulator. The finite element analysis software ANSYS simulation analysis was carried out, the results show that the topology optimization can effectively reduce the weight of the manipulator and improve the stiffness of the manipulator. Spring quality dynamic vibration absorber which is used effectively reduced the vibration of mechanical work, improved the working accuracy of the manipulator. Based on the study of this article, a rapid and reliable method was raised for the optimization design and vibration response of the manipulator control. This method can be applied to the design of other products.
