Finite Element Analysis And Optimization Design Of Key Part Of Forging Manipulator

Large-scale forging manipulator is not only one of the important auxiliary equipment inQuick Forging Hydraulic Press,but also a special loading arrangement of industrial vehicle,which holds the features of large loading, large inertia, multi-DOF, frequent palikinesia, topspeed and strong control.As for the huge forging manipulator, it firstly should reduce the quality on the premise ofthe application requirement, strength and rigidity. There are two advantages as follows: firstly,it can effectively save the materials and lower the consumption. Secondly, it can make themoving parts slower the rotational inertia, better the dynamic performance and lighten theload. An important aspect of influencing the quality of clamping equipments of the forgingmanipulator is whether the calculation of clamping force is reasonable. If the clamping forceis too massive, it may make the size of the whole equipment larger and increase thepossibility of uncertain factors. And when it may become worse, it may result in the fractureof the nippers arm, connecting rod and nippers.Therefore, this study firstly concentrates onthe establishment and analysis of the mechanical model，and calculates the most reasonablenumerical jaw clamping force by analyzing the different clamping force mathematicalcalculation model. So, the analyses of the application of clamping action and the rightcalculation method are the key part of designing clamping forces，and calculates the mostreasonable numerical jaw clamping force by establishing the different clamping forcemathematical calculation model.After elaborating analysis of the contact state when the jaw clamping the workpiece andthe study of the clamping force in different contact states, the calculation method of clampingforce which is accordance with the actual condition of practical application is worked out onthe premise of stable clamping. For example,taking30t forging manipulator, in order toreduce the quality of the key components, the research applies the finite element analysis andthe optimization of virtual simulation technology which can achieve the goal by deciding theoptimization target, constraint condition and design variable. It also provides an accessibleway of analysis of forging manipulator.This study applies the finite element analysis and the optimization of virtual simulationtechnology. The advantage is that different analysis model use different analysis software andeach software conducts certain data analysis. Through the interface of data transformationamong softwares, every finished design and data will be used each other to improve thedesign and the analysis effectiveness for the best and shorten the designing cycles and savetime. In the course of the traditional design, the complicated geometry parts can not be calculated by the way of strength theory in the field of engineering mechanics and materialmechanics, the results mainly coming from the experience, analogy and experiment. Themodern designing method can meet the actual needs of the engineering more than traditionalones, especially in the designing of the modern equipment. And it can help analysis thecomplicated structure models or assembly effectively, which also provide an accessible wayof analysis the forging manipulator.
