New Type Of Aluminum Ingot Palletizing Robot Finite Element Analysis And Optimization

In recent years the technology of piled buttress to obtain the rapid development, the robot piled buttress in particular the technological development really for swiftly and violently.This trend is emerging in today's manufacture of small quantities of multi-species adapted to the development trend. Aluminum ingot palletizing robot is a very important aspect of the whole production line of aluminum ingot. And palletizing palletizing robot is the executing agency for palletizing robot, It's lightweight and static and dynamic performance directly impact on the entire production line efficiency ToTheir research is the urgent necessary. Therefore, This article could conduct the system research to manipulator's sound of something astir state property, and by changed into the goal to carry on the structure optimization lightly, obtained the main research results were as follows:(1) Piled buttress the robot director--manipulator to the aluminum ingot to establish has conformed to the project actual three dimensional full-scale mockup. In the modelling has fully utilized the Pro/Engineer formidable entity modelling function and with the finite element software ANSYS compatible ability. Has carried on the static analysis to the manipulator, has obtained manipulator's under biggest work load function stress and the distortion. Satisfies the structure after the analysis very good design the intensity and the rigidity request, but the overall stress is low, the design is in favor of conservatively, has the very big optimized space. The analysis result also obtains the manipulator biggest stress and the distortion position, might provide the reference for the later structure optimization.(2) In order to avoid manipulator's various organizations in the promotion, the movement process has resonating or appears inspires harmfully, has carried on the modality analysis to the manipulator overall construction, has obtained the manipulator structure natural frequency resonance oscillation. Outside when design enables the frequency which these natural frequencies avoid drove to prevent the manipulator has resonating.(3) The aluminum ingot stacker code puts the aluminum ingot weight is 100kg belongs to the heavy load, the manipulator piles buttress the process to be able to have the inertia impact to the robot overall construction. In order to determine manipulator's under dynamic action of force stress and the response situation, this article chose the manipulator from to grasp the spindle to carry on the transient state dynamics analysis to most greatly highly this typical operating mode to it, Has obtained the manipulator in this process in the structure the node displacement, the speed, the acceleration along with the time variation response chart, provides the reference for later optimized design.(4) To the machinery manual static state analysis discovery, the current structure is in favor of conservatively, also overweight quality serious influence robot reliability and service life. Therefore carries on the optimization to the manipulator, its goal is in satisfies the structural strength rigidity and under the dynamic performance requirement condition reduces its itself weight. Has the better sound of something astir state property energy after the optimized obtained new structure, also the overall quality reduced 20%.
