Abstract

The invention relates to a pneumatic performance testing system for a wagon tarpaulin. The pneumatic performance testing system comprises data acquisition equipment, a multi-channel data acquisition port and an analyzing computer, wherein the data acquisition equipment is arranged on a wagon or the tarpaulin and is used for acquiring and obtaining data including tarpaulin stress, tarpaulin surface pressure distribution, drawing force of tarpaulin ropes and rope nets, wagon speed and surrounding air speed; the multi-channel data acquisition port is connected with each data acquisition equipment; and the analyzing computer is in communicating junction with the multi-channel data acquisition port and is used for analyzing the acquired data to obtain the pneumatic performances of the tarpaulin, the tarpaulin ropes or tarpaulin rope nets in different working conditions. The pneumatic performance testing system has the advantages of reasonable structural design and precise measurement, can obtain the pneumatic performances of the tarpaulin, the tarpaulin ropes or tarpaulin rope nets in different working conditions in real time, and realizes the security performance evaluation of the wagon tarpaulin and the security science evaluation of the tarpaulin, the ropes and the rope nets.

Description

technical field [0001] The invention belongs to the testing technology of the tarpaulin of railway freight cars, and in particular relates to an actual vehicle test and aerodynamic force analysis system for the tarpaulin of railway freight cars. Background technique [0002] Wagon tarpaulin is an auxiliary equipment for railway wagons. It is used to cover wet, flammable goods and other goods that need to be covered in open wagons. It plays an important role in railway freight. For a long time, due to the low level of containerization of railway freight in my country and the relatively limited number of boxcars, most of the goods (such as grain, fertilizer, etc.) are transported by open-top cars covered with tarpaulins. [0003] The force of the tarpaulin, tarpaulin rope and rope net directly depends on the aerodynamic effect during the operation of the truck. my country’s railway transportation has undergone six major speed increases. The speed of ordinary passenger cars is ...
