Dynamic Simulations And Optimization Design Of The Transmission Mechanism Of Vibration Staking Machine

The vibration staking machine plays an important role in the producing of leather, some deeply analysis about the problems exist in the transmission mechanisms of a symmetrical vibration staking machine with double rows are carried out. Then, some optimized options for solving these problems are suggested and checked. The main research work includes the following aspects:First, the parameterized three-dimensional models are imported into software ADAMS to build the virtual prototype model with actual loads and constraints. The mechanism is simplified as a slider-crank mechanism and the functions of the force in the bearings are calculated by theoretical analysis. The data got from MATLAB, ADAMS and actual test are compared in order to make sure the virtual prototype model is correct and based on these some important data which are the basic of later simulation are collected.Second, the exact reasons cause the failure of the belt transmission is found out after some parameters are verified. Three optimization options are suggested and the best option is selected after comprehensive analysis. In order to make sure the feasibility of the new belt pulley, life checking of the bearings are carried out.Third, the strength checks are carried out by the inertia relief and static structural methods in two different conditions so as to get the optimization leeway. Then actual strain measurement experiments are carried out to estimate the validity of finite element analysis.At last, in order to reduce the mass of the connecting rods, optimization analysis of the connecting rod are carried out combined with topology optimization and multi-goal driven optimization. The final optimization option is selected based on the results and reality and strength checks of the connecting rod are carried out again to make sure the optimized connecting rods are safe enough.
