A Method on Simulation and Parameter Design of Polyurethane Buffer

Abstract:

The polyurethane buffer is widely used in mechanical industry, intelligent manufacturing, internal combustion engine industry and etc.. The parameter design of the polyurethane buffer is often based on empirical formula with which it usually can not obtain the optimal parameter. This paper aims at studying the process of the buffer and optimizing its parameter. Firstly, the result of compression and shear tests of the polyurethane material is compared with simulation result to validate the simulation method is reasonable. Then buffers of different sizes with practical condition were simulated. During the simulation, this paper researched the maximum deceleration of the mass block in models with different sizes of polyurethane buffers. Lastly, the size of the buffer with minimum volume which is agreed with the request of the maximum deceleration of the mass block is obtained by data handling based on the simulation result, above on which a database was built.
