Optimum Design Of Crankshaft Press Test Bench

Innovative person of manufacturing is urgently needed abide with Made in china 2025 proposed,and the traditional higher education cannot adapt to the rapid development of the current manufacturing trend,university education reform has become an inevitable trend.Under the engineering design of electromechanical integration products stamping mechanical carrier and experimental application background,the development of series of stamping mechanical test bench,designed for the student to carry out the design,comprehensive,research-oriented experiments provide mechanical system integrated test platform,which is helpful to forge students' ability to solve complex engineering problems.This paper takes the double-point crank slider press in a series of stamping machines as the design research object,and carries out the motion design,scale design and structure design.Balance mechanism design and flywheel optimization design are carried out based on multi-body dynamics and structural performance analyses of key components are completed.The specific contents are as follows:Based on the requirement of crank press test bench design,general movement scheme design to press the power end,analyzing the characteristics of the different design scheme,establish kinematics analysis mathematical model,press the power end components by analytical method to solve kinematics characteristic,according to the kinematic characteristics to scale design of key parts of the crankshaft,connecting rod,the crankshaft,connecting rod,the slider,enclosure structure design.This paper build accurate motor driver model,solve the two point slider-crank stamping machine redundant constraint processing problems,complete the designed machine prototype,use Adams multi-body dynamics virtual simulation technology to solve the dynamic movement performance,come up with a design method of the flywheel process with real speed fluctuation coefficient,flywheel size,electrical energy consumption for the scheme evaluation index,optimize the design of the flywheel is feasible.The traditional flywheel approximation design problem is solved.The dynamic static analysis model of crank press is established and solved by theoretical analysis.Due to the inertia force and moment of inertia caused by the movement of crank slider mechanism,the mechanism balance design of crank press is carried out by using partial balance method.Considering the influence of elastic deformation of crank-press components,the modal analysis of crankshaft and connecting rod of key components is carried out by using ANSYS finite element analysis software,and the modal neutral document MNF is generated.Simulation and analysis of rigid-flexible coupling dynamics model is built in ADAMS.The advanced brown-miller fatigue analysis theory combined with ANSYS is used to predict the service life of crankshaft and connecting rod structures of key components according to the results of dynamic analysis...
