ABSTRACT
|
Longitudinal dynamic analysis for 20-groupage, 18t-axle-load
high-speed wagons under the operation of service braking and emergency braking
were investigated using longitudinal dynamics analysis system, which was based
on air brake system emulation. According to the simulation results, the longitudinal
impulsion was differentiated into two parts, which were extrusion coupler force
and impact coupler force. Some advises were also put forward to reduce the
longitudinal impulsion.
