DAMPING SYSTEM FOR RAIL CAR TRUCK AND METHOD OF DESIGNING RAIL CAR TRUCK

摘要

Rail car truck utilizes friction wedges for damping device is supported by the side spring to alleviate relative movement between the side frames for supporting the pedestal with the railway car truck pedestal. Each friction wedge is formed of a general triangle with the angle θ formed between the inclined surface friction moving relative to the friction surface and the vertical stand leaning against the side frames. The force P of each side spring and θ is defined by the following.
