Coupler for a railway vehicle, with a rubber damper and energy absorbing members |
摘要 |
<p>A mounting structure of a rubber damper (1) for a coupler (11) of a railway vehicle is capable of stable bellows-like deformation and of relieving a collision load and acceleration caused by collision between vehicle body frames. A coupler (11), a rubber damper (1), and energy absorbing members (12L,12R) that are tubular with square cross-section are arranged in this order in the longitudinal direction of a vehicle body. The vehicle body frame is configured to receive a collision load in the longitudinal direction which is transmitted through the energy absorbing members (12L,12R). When Young's modulus of a material of the member is E and a yield stress of the material is sigma y, a relationship between a width B of the member and a wall thickness t thereof is represented by B ≤ (t/0.526)(E/ sigma y)<1/2 >. <IMAGE></p> |
