| Abstract: | Dynamic performance of the mechanical system,which is composed of a shaft and two rolling bearings,is studied in this paper.First a rolling bearing 6310 is studied to obtain the formula between the applying load and the relevant displacement,and the problem is regarded as a static indeterminate problem and the Hertz theory is also used to solve it.Then the numerical solution is acquired.Two dynamical problems on variable loads are discussed for the system,one is to treat the shaft as rigid body and the othe... |
