Abstract Abstract Abstract Abstract : : : : Boxcar is one of the most versatile of railway freight cars.By the end of 2002,China
has freight car of 91835 boxcars,accouting for about 20% of the total number o f freight
cars. Since the founding of new China, China has gradually formed the ability of independent
development and manufacturing of railway boxcars. Railway wagons for goods, LTL cargo and
bagged box packaging goods transportation from the sun snow or rain, can transport a wide
range of goods, versatility, high utilization rate,transportation advantages, will be more and
more welcome by the owner, the vast market potential market demand, the contradiction of
railway wagons the product demand and railway boxcar actual capacity will gradually appear.
So far, China's general boxcar load capacity has reached 70t, and made great contributions to
the development of the national economy, thus the boxcar development of our country's
experiences and lessons, and actively carry out research on general boxcar technical scheme of
80t,defining the main technical parameters, to reserve wagon technical separation of passenger
and freight traffic, meet the need of the development of the railway transportation in China, has
become a very urgent issue.
This paper introduces from the early days to the beginning of this century in the process, each
stage has some representation of the basic model, the basic structure of each model and the
existence of the problem.As the development of new materials,new technologies continue to be
born and railway freight car bogie, coupler, improve brake parts and other supporting
technology. Now, the development of 80t grade of general boxcar has become a reality.
