CURING SIMULATION OF FOUR AXLE RAILWAY VEHICLES WITH CONVENTIONAL TWO AXLE BOGIES

We developed a dynamic model for curving of four axle rail vehicles with conventional two axle bogies, and derived equations of their motion. Then some digital simulations were made to obtain time history of rail-wheel vertical and lateral forces during curving. In the case of an ordinary truck, it is shown that it runs on curved tracks with its outer wheel of the front axle slipping between the flange and the rail, as is well known. However, slipless curving is achieved by a proper selection of parameters. This simulation was also applied to those cases where dynamic coupler forces were applied, and there was a lateral rail irregularity.
