Method for determining specifications of rubber structure, method for manufacturing rubber structure, and rubber structure

摘要

PROBLEM TO BE SOLVED: To provide a method for determining a specification of a highly versatile rubber structure capable of suppressing stick-slip vibration and wear, a method for manufacturing the rubber structure, and a rubber structure. SOLUTION: When determining the specification of a rubber structure 1 having a rigid body layer 4 embedded in vulture rubber 3 and having a contact surface 2 that slides with respect to a target surface 6 during use. As 1, the rigid body layer 4 is arranged at a predetermined depth h from the contact surface 2, the rubber layer 3a having the contact surface 2 and the rigid body layer 4 are laminated, and the upper surface of the rigid body layer 4 is fixed to the fixed end 5. The analysis model 1A was set, and the mass m, elastic modulus k and viscous damping coefficient c of the rubber layer 3a, and the mass ma, elastic modulus ka and viscous damping coefficient ca of the rigid body layer 4 were set so as to satisfy the equation (1). The rubber layer 3a and the rigid body layer 4 have the specified specifications, and the rubber structure 1 is manufactured. λ2 (1-Ze) 5 / Zeff <4π ... (1) [Selection diagram] Fig. 4
