Above-mentioned two kinds of existing test units can not satisfy the demand of existing test standard.
Summary of the invention
The objective of the invention is to overcome the existing not high and bad adaptability of test unit test accuracy, complex structure, shortcomings such as difficult processing adopt the inverted T shape agent structure, make the vibration frequency coverage of test become big and a kind of test unit design.
For achieving the above object, design a kind of universal CAB impact shock test unit, comprise agent structure, reinforcement, contiguous block, bolt that base plate and main substrate constitute, it is characterized in that: the vertical inverted T-shaped agent structure that is connected to form of base plate with main substrate, on main substrate, be laid with fixed orifice, adopt bolt that contiguous block is fixed on the fixed orifice, described inverted T-shaped agent structure is provided with reinforcement.
Described inverted T-shaped agent structure is to adopt that main substrate is vertical with base plate to be connected to form single inverted T-shaped agent structure; Or two vertical pair inverted T-shaped agent structures that are connected to form of parallel main substrate before and after adopting with base plate.
Also be respectively equipped with lightening hole on main substrate or the reinforcement.
Be laid with mounting hole on the base plate.
Its outer end of described contiguous block is a profile, and this profile is provided with connecting hole.
The present invention compares with prior art, constitute T shape or double T shape agent structure by one of the vertical connection of base plate or two main substrates, again in conjunction with plurality of strengthening ribs, simple in structure, be beneficial to the axis of the combined gravity of curtain air bag to be tested and anchor clamps by shaking table, enlarge frequency coverage, effectively shorten the process-cycle, reequip with low cost; And each critical piece is monolithic sheet material and constitutes, and has reduced to cooperate and prestressed problem; Each critical piece provides support on all directions mutually, has improved overall architecture stable of test unit; Can adjust the assembly structure of contiguous block according to the actual requirements; Can be combined into the different test unit of length according to different product and testing requirements; Adopt bolt to be connected to the master, be aided with local welding, effectively reduce welding deformation.

Embodiment
Now in conjunction with the accompanying drawings the present invention is further described.
Universal CAB impact shock test unit among the present invention, hereinafter to be referred as: test unit, mainly comprise base plate, main substrate, reinforcement, contiguous block, bolt, referring to Fig. 3, Fig. 4, wherein,
Base plate 1: be mainly used in fixedly whole test device, adopt aluminum alloy plate materials, can lay mounting hole 6 in advance on the base plate 1, mounting hole 6 parts are used to connect main substrate 2, and another part is used for fixing on shaking table to be used.
Main substrate 2: main effect is a carrying curtain air bag to be tested, adopt aluminum alloy plate materials, form by the CNC machine tooling, in order to carry the needs distribution plurality of fixed hole 7 of curtain air bag to be tested, these fixed orifices 7 are connected with contiguous block 3 by bolt, two ends, the nearly left and right sides of main substrate are respectively equipped with lightening hole 5, not only reduced the weight of test unit effectively, and the long curtain air bag to be tested of length is passed through from it, fix around the back side, increase the adaptability of test unit to main substrate.
Reinforcement 4: be mainly main substrate 2 the brute force that adds on the main substrate fore-and-aft direction is provided, also can establish lightening hole 5 as required on the reinforcement 4, under the prerequisite that guarantees structural strength, played the effect of weight reduction.Can add and reduce the quantity and the position of reinforcement according to actual needs arbitrarily.
Contiguous block 3: effect is being connected on the test unit curtain air bag to be tested, with the profile of the contiguous block 3 of curtain air bag junction to be tested on, profile can be formed by Cutter Body Processing with Machining Center according to the angle of different curtain air bags in real vehicle, contiguous block 3 other ends are installed on the main substrate 2 by bolt, simulate the real vehicle state with this.
Bolt: adopt 12.9 grade high-strength bolt tensile strength to reach 1200mpa, yield strength reaches 900mpa.
As required, on base plate 1, lay some mounting holes 6 earlier; On main substrate 2, also lay plurality of fixed hole 7; On the profile of contiguous block 3, also set in advance and be used to connect the connecting hole 8 that curtain air bag to be tested is used; Main substrate 2 is by mounting hole 6 employings and bolt and the base plate 1 vertical inverted T-shaped agent structure that is connected to form of corresponding position on the base plate 1, adopt bolt contiguous block 3 to be fixed on the fixed orifice 7 of main substrate 2 corresponding positions again, owing to lay fixed orifice 7 on the main substrate 2, so contiguous block 3 can be fixed on any position of two sides, main substrate 2 front and back as required; All the other mounting holes 6 by base plate 1 during use are fixed on the shaking table of test usefulness, above-mentioned inverted T-shaped agent structure, can adopt that a main substrate 2 and base plate 1 are vertical to be connected to form single inverted T-shaped agent structure, referring to Fig. 3, also can adopt two parallel main substrates 2 in front and back and the base plate 1 vertical pair inverted T-shaped agent structures that are connected to form, just form a groove shape structure between such two main substrates, referring to Fig. 4, the quantity that the curtain air bag to be tested that this pair of inverted T-shaped agent structure can increase in the test unit to be connected is used;
