Motion Simulation And Optimization Analysis Of The Transmission Mechanism On Elbow-bar Mechanical Press Based On ADAMS

Mechanical press is widely applied in the industrial field of automobile,electronics,military,aerospace and other important,especially in recent years with the rapid development of the automobile industry and the production scale,the press is becoming more indispensable in the production process for forging equipment stamping,drawing,blanking process.With the development of science and technology and industrial technology level unceasing enhancement,the traditional crank press due to lower punching accuracy and processing efficiency,it has been unable to meet the pressing market increasingly high demand for production.The elbow-bar type mechanical press because of its quick return characteristics,boosting effects,has increasingly been applied to the field of forging.So it is very important to improve the working performance of the mechanical press which is widely used in the field of industrial production.The transmission mechanism of the mechanical press is the core part of the press,the unreasonable design of the parameters of the mechanism will affect the performance of the press,and then affect the quality of the product.Aiming at the above problems,this paper proposes and analyzes the simulation of kinematics parameters using ADAMS software,using the virtual prototype model of the elbow-bar type mechanical press,put forward an optimization design of mechanism model with multi objectives,ultimately enhance the overall performance of the elbow-bar type mechanical press transmission mechanism,so as to improve the quality of the products.At present,domestic and foreign scholars are using Matlab or ADAMS software to do the simulation analysis and optimization of the elbow-bar type mechanical press,the research proves that the elbow-bar mechanical press transmission mechanism with quick return characteristic is very good,and the reinforcement effect is obvious.This paper is based on the research of scholars at home and abroad,firstly expounds the classification and the motion characteristics of mechanical press,introduces the current research status of domestic and foreign scholars in related fields,and took the elbow-bar the mechanical press as the research object,the transmission mechanism of the press is analyzed for kinematics analysis and mechanism based on size;and modeling the mechanism of parameterized virtual prototype using ADAMS software to verify the correctness of the mechanism model of parametric coordinates and successfully carried out the model of self,through kinematics simulation analysis of the influence of the characteristic curve of the sliding block mechanism performance;in order to improve the stability of motion,improve quality and prolong the stamping die service life,through the creation of design variables,establish the constraint function and objective function is proposed to reduce the working process of institutions Multi objective optimization design of speed fluctuation,slider to reduce the maximum pressure in the working process and reduce the angle of slider acceleration peak value as the goal,and the optimization of the organization model are calculated and analyzed the optimization module of ADAMS/Insight test,getting the better design parameters with comprehensive performance of the transmission mechanism.Through the simulation analysis of the mechanism model before and after optimization,and comparing the characteristic curves of the slider before and after optimization.The simulation results showed that the comprehensive performance of the mechanism is improved obviously.This paper provides a theoretical basis for the motion simulation and optimization analysis of the transmission mechanism on elbow-bar mechanical press.
