Abstract

The invention relates to the mechanical technology field, more particularly to a testing apparatus of impact vibration of general curtain air bag (CAB). The apparatus comprises a main body structure consisting of a base plate and a main substrate, stiffeners, a connection block, bolts. The apparatus is characterized in that: the base plate and the main substrate are connected vertically to form the main body structure of an inverted T shape; Fixed orifices are arranged on the main substrate, and the connection block is fixed on the fixed orifices by bolts; and the main body structure of an inverted T shape is provided with the stiffeners. Compared with the prior art, the technology employed in the invention is characterized in that: a T-shaped or a double T-shaped main body structure is employed; and a plurality of stiffeners are combined. In addition, the apparatus with a simple structure enables a center of gravity of combination of the to-be-tested CAB and a clamp to pass an axis of a vibration table easily. Moreover, according to the invention, a frequency coverage range is extended, a processing cycle is effectively shortened, and the modification cost is low; an integrated framework is stable; an assembly structure of the connection block can be adjusted according to an actual demand; Welding deformation is effectively reduced because of the focus of utilization of connection by bolts.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a general-purpose CAB shock vibration test device. Background technique [0002] With the development of the automobile industry and the improvement of the country's technical requirements for automobile safety, the requirements for various car occupant safety simulation tests are also getting higher and higher. CAB is the abbreviation of Curtain Air Bag, which means curtain airbag, which is a key safety component to protect the head of the occupant in the event of a side collision of the vehicle. This type of airbag has: large span L>1.5m, large drop from the lowest point to the highest The point can be up to 400mm, and the angle of involvement is numerous. The angle of each fixed point is different. In order to better simulate the state of the real vehicle, this puts forward high requirements for the installation of the curtain airbag to be tested during the mechanical sh...
