Railway heavy haul transport is the main technological way to improve the transport capacity of large cargoes. And increasing the axle-weight of vehicle and improving the load of vehicle are important measures to develop the railway heavy haul transport. On the premise that the structure strength and stiffness of vehicle meet the requirements, it is a primary issue that the weight of vehicle structure has to be reduced.
This paper focused on the research of the body structure of heavy load gondola car w...
