Mechanical Properties Analysis and Optimization of Local Key Parts of a Scraper Conveyor
In order to further explore the mechanical properties of key components of the scraper conveyor,this paper takes the SGB620/40T scraper conveyor as the research object,and analyzes the mechanical properties of the local key component of the chain drive system,which is prone to wear,and determines the problem that the structure is prone to wear through the finite element analysis method,and further applies the mathematical method to construct the optimization function.The structure is optimized.The results show that the strain variable of the optimized chain drive system is significantly reduced,from the initial 7.998mm to less than 0.8mm.Therefore,it can be considered that the optimization method can theoretically improve the operating performance of the chain drive system of the scraper conveyor.
