Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] Such as figure 1 As shown, the vehicle body side wall load loading device of the present invention includes an experimental platform, a force applying mechanism and a counterforce mechanism. The experimental platform includes a table 9, which is used to accommodate the vehicle body 1 to be tested. The force application mechanism and the reaction force mechanism are respectively installed on both sides of the vehicle body 1 to be tested. The table top 1 is also provided with a ground chute (not shown in the figure), and the ground chute is used for installing a force application mechanism and a reaction force mechanism. Such as figure 1 As shown, the force applyin...

Abstract

The invention relates to the technical field of vehicle body strength testing and discloses a vehicle body side wall loading device. The device comprises a test platform, a force application mechanism and a reaction mechanism. The test platform comprises a platform top used for holding a vehicle body to be tested. The force application mechanism comprises an airbag fixing plate, a loading airbag and an air pressure control unit. The airbag fixing plate is vertically mounted on the platform top. The loading airbag is mounted on the inner side of the airbag fixing plate. The air pressure control unit is communicated with the loading airbag. The reaction mechanism comprises a reaction support member and a force sensor. The reaction support member is mounted on the platform top. The inner side of the reaction support member is pressed against the vehicle body to be tested. The force sensor is disposed between the reaction support member and the vehicle body to be tested, and is connected with an external data acquisition device. The vehicle body side wall loading device has the advantages that applied load can be evenly distributed on the side wall of the vehicle body, the transverse bending property of the vehicle body and the airtightness and structural strength in windows and doors can be detected, and safety of the vehicle body can be assessed accurately. The invention further provides a vehicle body side wall loading method.

Description

technical field [0001] The invention relates to the technical field of car body strength testing, in particular to a car body side wall load loading device and a load loading method. Background technique [0002] With the rapid development of domestic rail transit, high-speed EMUs and urban rail vehicles have been widely used. In order to meet the needs of the development of rail transit, it is necessary to better understand the various performances of the vehicles and ensure the quality of the vehicles provided. It is very necessary to carry out more realistic strength tests and local structural tightness tests on the car body. Existing rail vehicle tests do not have a test device and method for the side wind force of the car body. Only in the static strength test of the car body, the side wind force is converted into a certain amount of vertical load and applied evenly to the floor inside the car body. There is a lack of a targeted uniformly distributed loading method an...
