| Abstract: |
| The feasibility of the target mechanical properties of the lead rubber bearings（hereinafter referred to as bearings） was analyzed by finite element method.Regarding the Y4Q470×180 type bearing，without changing the yield strength of the lead core，in order to improve the yield strength of the bearing and maintain the post-yield stiffness remained basically unchanged or changed little，the influence of the rubber material shear modulus，lead core diameter and lead core number on the yield strength and post-yield stiffness of the bearing was analyzed by Abaqus software，and the parameter combination to achieve the target mechanical properties of the bearing was obtained.Experimental verification was conducted on the mechanical properties of several types of the bearings，and the deviations between the test results and the calculation results were within the allowable range. |
