A suspension system structural design of the bogie of 80t general purpose gondola
Abstract: China's railway freight development by leaps and bounds since the rail freight
capacity has been significantly improved, but still can’t meet the increasingly growing demand
for cargo transport. Therefore, the continuous development of China in recent years in large
truck of trucks, and gondola is one of them. The gondola’s mean is having side walls, end walls
and the floor and without roof, upwardly open wagons. It is mainly responsible for transporting
coal, ore, building materials (including wood, steel) and other bulk cargo use, but also bear the
weight of the shipment is not mechanical equipment. Gondola by way of discharge can be
pided into two categories: one kind is Suitable for manual or mechanical handling operations
generic gondola; The other is applied to a fixed grouping column transport between major industrial and miming enterprises, station and dock with a dumper unloading gondola, and
special gondolaUniversal gondola is the main railway cargo transportation vehicles, papers to 80t class A
common gondola bogie suspension system for the study, a series of bogie suspension system
structures were designed to provide the basis for the optimum design. Now the inevitable
development of selected countries in the world is the big heavy transport axle load, so common
gondola 80t class bogie using 25t (K5 type) axle load, the highest commercial operation speed
bogie 120km / h, to meet the design requirements .
This paper focuses on the development status of heavy-duty trucks as well as its truck
usage, analyze the existing heavy-duty trucks at home and abroad - axle structural properties
and structural characteristics of the system, initially identified in line with China's national
conditions and the status of railroad freight car bogies load of 25t axle load of 80t (K5 type) of
a suspension system for structural type, the use of kinetic knowledge bogie, bogie dynamic
model and its parameters to optimize the design.
Key words: General purpose gondola；25t axle；bogie；A suspension system
