Considering the difficulty of contact stiffness identification of multiple floating splines in complex misalignment, a contact stiffness identification method based on test and thin-layer element simulation was proposed. Based on thin-layer elements, the finite element model of the radial transmission rod with multiple floating splines was established, the natural characteristics of the radial transmission rod with multiple floating splines were simulated, and the stiffness recognition function of the multiple floating splines was constructed by combining the natural frequency test data of the radial transmission rod, so as to accurately identify the contact stiffness of the multiple floating splines. The variation law of floating spline contact stiffness with torque and misalignment was obtained. The results showed that the contact stiffness of floating spline pair was enhanced with the increase of torque, while the contact stiffness of spline was reduced with the increase of misalignment angle. At low torque, misalignment weakened the spline stiffness obviously. At high torque, the effect of torque on spline stiffness was obvious. By replacing the contact stiffness of spline contact surface with thin layer element, the modal frequency of spline in different contact states can be calculated more accurately. The research results can provide some reference for the accurate identification of the contact stiffness of floating spline, and can be directly applied to system dynamics analysis.
