The explosion impact waveform generating device is fixed on the ground, the impact waveform is simulated by vertical collision impact with a rigid frame provided with the lightning protection seat, and the waveform curve of the impact acceleration is used as the judgment standard for the success of the simulated waveform.
As shown in fig. 1, the armored car seat stand includes a test stand 1, a rigid frame 2, an explosion impact waveform generating device 3, a high-speed camera 4, and a lifting device 5. The lifting device 2 is arranged on a cross beam at the top of the test bed 1, the rigid frame 2 is arranged below the lifting device, and a test piece is arranged in the rigid frame. The explosion impact waveform generating device 3 is arranged on the ground, and a high-speed camera 4 is arranged beside the explosion impact waveform generating device.

As shown in fig. 2, the explosive shock waveform generator is composed of a fixed base 31, anchor bolts 32, a load sensor 33, a sensor adapter flange plate 34, an upper impact table 35, a buffer unit 36, an impact panel 37 and an accelerometer 38. The fixing base 31 serves to fix the blast impact waveform generator 3, has a U-shaped hole for installing the ground rail in a matching manner, and is connected with the ground rail through the anchor bolt 32. The total number of the load sensors 33 is 4 or 6, the load sensors are disc flange type three-way force sensors for bearing impact, the load sensors are distributed around the fixed base 31 and connected with the fixed base 31 through bolts, and the sum of the measurement results of the sensors is the value of the impact load. Sensor flange plate 34 is the same with load cell's quantity, has two sets of connecting holes, and one set is connected with load cell 33 through the bolt, and another set is connected with last striking mesa through the bolt, and its effect is by two aspects: the installation and the positioning of the load sensor are facilitated; and the adapter flange plate can be used for fine adjustment of the installation height and angle of the sensor, so that the levelness of the upper impact table is ensured, and the measurement accuracy is ensured. The upper impact table 35 is provided with a counter bore and is connected with the adapter flange plate 34 through a counter bolt, and the upper surface of the upper impact table 35 is provided with a plurality of clamping grooves with the same thickness for embedding and fixing the buffer unit 36. The buffer unit 36 may be a plurality of natural rubber blocks, urethane rubber, lead blocks, composite energy absorbing materials, etc., preferably rubber blocks, with the same hardness and thickness. The damping unit 36 must ensure that the thickness of the rubber mass is the same, to ensure that the entire rubber mass is compressed simultaneously at the moment of impact. The impact panel 37 is mounted by welding on the bottom of the rigid frame (containing the test piece) 2, and is a thick steel plate with sufficient thickness to ensure its rigidity and high enough flatness to ensure that the impact moment simultaneously touches the rubber block of the cushioning unit 36, and the impact panel 37 also needs to have sufficient size to ensure the full area of the contact exchange material 36.

The rubber block is taken as an example in the following, a simulation method of the impact waveform is given, and design parameters of the buffer unit can be obtained through a calculation method. In order to facilitate adjustment, the rubber blocks are made into a plurality of blocks, and the number of the blocks can be increased or decreased through the test actual measurement result so as to obtain the waveform pulse width meeting the requirement.
Next, the selection and design process of the buffer unit 36 of the waveform generating apparatus 3 will be described.

Assuming that the stiffness k of the waveform generating device is linear, the kinetic equation of the system is expressed as
From the initial condition t being 0, X being 0,
solving the differential equation can obtain
Wherein:
is the system natural frequency;
is an initial phase angle;
the amplitude of the shock acceleration pulse can be obtained as follows:
the impulse width of the impulse waveform, i.e. the time between the impact duration tau and the value at which the acceleration of the impulse is zero, is obtained by neglecting the initial phase
Through the method, the rigidity of the buffer unit 36 of the waveform generating device can be obtained according to the waveform conditions required by the seat bench test and by matching with the design parameters of the test bench, so that the hardness and the type of the rubber are determined, and the design of the waveform generating device is completed. The selection of the buffer unit 36 of the waveform generating device and the test analysis and evaluation process of the experimental waveform are realized by computer programming, the hardness of the rubber material is automatically selected when the design is finished, and the autonomous judgment of the simulation result is finished in the test debugging process.
When the invention is applied to a bench test, the installation of the test bench and the waveform generating device 3 is firstly completed, and the load sensors 33 pass the standard inspection/identification before the waveform generating device is formed. The installation position of the waveform generating device 3 is determined according to the installation position of the test bed and the falling impact position of the rigid frame (including the test piece) 2, the device is fixed on a ground rail through the foundation bolts 32, looseness and slippage of the device are avoided in the impact process, and the impact panel 37 can press all the buffer units 36. After installation, the rubber blocks of the buffer unit 36 are laid in the slots of the upper table-board according to the theoretical value.
And finishing the adjustment of the waveform through drop debugging. The rigid frame (including the test piece) 2 is lifted to the theoretical height through the test bed, sensors such as the load sensor 33 and the accelerometer 38 are cleared, the test bed is opened to release the lock, the rigid frame (including the test piece) 2 is put in, the impact panel 37 impacts the buffer unit 36, and the acceleration value of the whole impact process is measured through the acceleration and 38 at the moment, namely the impact waveform. The waveform data is based on data obtained by filtering CFC1000, the obtained impact waveform is compared with the required waveform, and if the required waveform is not met, the waveform is adjusted. When insufficient waveform peaks are detected, the drop height of the rigid frame (containing the test piece) should be raised, and conversely, the drop height should be lowered. When the measured waveform pulse width is not satisfactory, the problem is solved by adjusting the rigidity of the ground buffer unit 36, when the pulse width is too small, which indicates that the rigidity of the buffer unit 36 is too large, the buffer unit 36 with smaller rigidity should be replaced or the rubber quantity of the buffer unit 36 should be reduced, otherwise, when the pulse width is too large, the buffer unit 36 with large rigidity should be replaced or the rubber quantity of the buffer unit 36 should be increased.
The formal test process is the same as the debugging test, and the impact panel 37 impacts the buffer unit 36 to generate a required waveform, so that the explosion impact is simulated, and the seat response in the whole process is measured. The device can measure the load during an impact and provide an impact waveform.
