摘要：

In order to solve the durability problem of laminated rubber bearing, a mental rubber bearing was presented.The construction, working principle and characteristics of metal rubber bearing are introduced.The key technical parameters of metal rubber bearings are given, and 7 metal rubber bearings of 3 groups are designed and processed.The compression test was carried out on the 500kN electronic universal testing machine.The load displacement relationship of the metal rubber bearing is obtained.The influence of density and shape coefficient on compression curve is investigated.The parameter identification of compression curve is carried out by using function expression.The results show that the loading compression curves of metal rubber bearings can be divided into two stages: the soft characteristic stage and the hard characteristic stage.The soft characteristic stage of the bearing compression curve decreases with the density increasing.The vertical energy dissipation capacity of the bearing decreases with the density increasing.The loading and unloading curves of theoretical calculation agree well with the experimental data.The research results can guide the design of vertical bearing capacity of metal rubber bearings. © 2021, The Editorial Board of Journal of Basic Science and Engineering.
