Abstract

The invention relates to a safety blast resistant structure used for testing alternating bending stress, which includes five defense lines that have protective effect on possibility of damage on a downward in-place travel switch and a dropping stopping travel switch due to blast wind. The first defense line is a blast resistant separation board; the second defense line is a hair felt; the third defense line is a defense line is a blast resistant middle separation board; the fourth defense line includes a left blast resistant gas guiding protective wing, a right blast resistant gas guiding protective wing, a front blast resistant gas guiding protective wing and a rear blast resistant gas guiding protective wing; the fifth defense line includes a left lower part machine box body gas relief pore group, a rear lower part machine box body gas relief pore group and an upper-right lower part machine box body gas relief pore group. After the blast wind passes through the five defense lines, impact on the downward in-place travel switch and a dropping stopping travel is reduced to a very slight degree.

Description

technical field [0001] The invention relates to a force testing device for a vehicle wheel hub, in particular to a test device for bending a vehicle wheel hub under alternating force. Background technique [0002] With the development of society, vehicles have become the main means of travel for people, and the safety performance of vehicles is closely related to the safety of personal life. As the main part of the vehicle, the hub bears all the gravity of the vehicle, various impact forces during travel and bending force when turning. When the vehicle turns, the hub will be subjected to bending force. This force is an alternating state. The force of this alternating state will lead to deformation, sudden fracture and fatigue fracture of the hub. Once the wheel hub is damaged, the vehicle will lose control and easily cause traffic accidents. [0003] Existing test equipment for wheel hub stress bending can generally only test the static force condition of the wheel hub, an...
