In this paper, test research have been performed on the two important mechanical properties indicator compressive modulus of elasticity and shear modulus. Numerical simulation has been performed on the base of results of test under the situation uniform and uneven thickness of elastomer layer, which analyze internal stress distribution of the elastomeric bearing, as follows:(1) The traditional test methods of compressive modulus of elasticity test are rather cumbersome and take up experimentalists lots of time. This paper has improved the traditional test methods of compressive modulus of elasticity test, which has collected the holding-load time together to concentrate on holding load. The tests have been performed on different types of bearings, which results show that the results of the improved test method conform to the error range regulated by the standard and can effectively save time for the experimentalists, also eliminate the accumulative error.
