In this paper, the concept of flexibility coefficient is introduced in solving the problem, and the interaction between each piece of roller is considered. On the basis of previous studies, LiewandLim studied the relationship between the stiffness caused by the orbit motion of rolling body and the change of time. The theoretical model does not include some parameters that have important influence on the bearing stiffness, such as axial clearance, radial clearance, raceway width and thickness, and the radius of the inner track. Therefore, in practical application, these theories are not accurate enough and limited. In this paper, the self-programming is used to calculate the bearing stiffness of three row roller turntable under different working conditions, and the influence of clearance, external load, roller number on the bearing stiffness is discussed.

With the development of experimental technology, the vibration response of rotor-bearing system is used to obtain the bearing dynamic parameters. Based on the unbalance and impulse response of the rotor-bearing system test bench, Tiwai determines the dynamic stiffness of the supporting bearing through identification technology. Based on the vibration response recognition technology of rotor-bearing system, G ○ ○ dwii tests the stiffness and damping of bearings. The above method is applicable to any type of rolling bearing, and the vibration response identification technology of rotor-bearing system is often used as the method to determine the bearing stiffness.

The research on the stiffness of bolt joints focuses on the pressure distribution of bolt joints. Tong et al. proposed an ideal bonding surface, where the contact pressure of the joint formed by the surface of two components is equal and the contact points are evenly distributed.
