A feasible method to improve the reliability and processing efficiency of large vibrating screen via the application of an elastic screen surface with multiple attached substructures (ESSMAS) was proposed.In the ESSMAS,every screen rod,with ends embedded into elastomer,is coupled to the main screen structure in a relatively flexible manner.The theoretical analysis was conducted,which consists of establishing dynamic model promoted from the fuzzy structure theory as well as calculating for the equivalent stiffness of each attached structure.According to the numerical simulation using the NEWMARK-β integration method,this assembling pattern significantly leads to the screen surface/rod having larger vibration intensity than that of the corresponding position on screen structure,which specifically,with an averaged acceleration amplitude increasing ratio of 11.37％ in theoretical analysis and 20.27％ in experimental test.The experimental results,within a tolerant error,also confirm the established model and demonstrate the feasibility of ESSMAS.
