Dynamic Performance Analysis On The Turnover Mechanism Of Aluminum Ingots Stacker

In this paper,it studies the transmission system of The Tipping Gear which are the key components of Aluminum Ingots Stacker in detail,and discusses the dynamic optimization in the application of the transmission system.The devices are based on a set of 22 t/h output of aluminum ingots continuous casting production lines.The main axis is an important part of The Tipping Gear and bears the main torque in the course of work.The performance of The main axis has a significant impact on the whole of the device,therefore,we do some static and dynamic performance of it.In the analysis before we should determine the stiffness and damping of the spindle bearing.After the establishment of appropriate static model,we receive the torque of spindle under the maximum rigidity with the use of finite element analysis software ANSYS calculation.After established a dynamic model of spindle we have some research on the modal Analysis and transient response Analysis of it and get the natural frequency of vibration mode and the response of displacement,speed and acceleration under transient loads.This thesis has a research on dynamics characteristics of The Tipping Gear's transmission system.The dynamics model of The Tipping Gear on the basis of the Riccati transfer matrix method is set up through confirmed inertia element and elastic element,and its corresponding mathematics model is set up too.Some characterization parameter of its intrinsic characteristic are obtained while getting torsional vibration of the tipping gear through the numerical simulation of the computer to use MATLAB,and then a detailed analysis is carried directly on them.The transmission system is Optimizatized through the principle of modal flexibility and energy distribution.This thesis put a improved method with flexible degree of modality want to be small,distributing rate of elastic energy and distributing rate of inertia energy drive to equality is a target of optimum design.The improved method is modified rigidity and rotary inertia in The Tipping Gear minor structure.The rigidity and quality revising the sub-structure of the transmission was put forward.In addition,as to the thing that the high distributing rate of elastic energy of the sub-structure,its damping must be increased.And the dynamic performance of The Tipping Gear improved is forecastedThe dynamic characteristics of this model of The Tipping Gear is analysed and optimizatized.In this sense,it provided the certain theoretic evidence for the optimum design manufacture of it.
