Abstract
By analyzing the roller force, the nonlinear stiffness model of the double-row tapered roller hub bearing is derived, and the method of solving the hub bearing stiffness matrix is summarized: if the displacement between the inner and outer rings is known, the stiffness of the hub bearing can be directly calculated. If only the external load of the hub bearing is known, the displacement of the hub bearing needs to be solved by numerical method, and then the stiffness of the hub bearing can be calculated. The improved Newton-Raphson method is used to solve the stiffness matrix of the hub bearing. Three-dimensional FE model of DRTRBs is presented and validated the proposed the stiffness matrix of the hub bearing. It is found that the radial stiffness of the hub bearing is greater than the axial stiffness. The stiffness of the hub bearing is greatly affected by the vertical force of the ground and the wheel driving torque, showing obvious nonlinearity. The smaller the vertical ground load and wheel driving torque, the greater the influence of vertical ground load and wheel driving torque on the hub bearing stiffness.

Summary
Double-row Tapered Roller Bearings (DRTRBs) are designed to support the preload, axial load, radial load, and torque in static and dynamic conditions [1, 2]. De Mul et al [17, 18] computed analytically the bearing stiffness matrix of roller bearings based on the theory of Jones [12] and used internally in the iterative bearing equilibrium calculation. Tong and Hong [4, 19] presented time-varying stiffness matrix of tapered roller bearings (TRBs) based on the bearing stiffness matrix based on the theory of De Mul et al [17, 18]. The research papers did not covered the stiffness derivation of DRTRBs
