Abstract
The present invention relates to the waveshape generating devices of impact test, provide a kind of water tank type waveshape generating device.Impact test process is to hit waveform generator, waveform generator absorbs impact energy, and generates the waveform of customization after testpieces obtains rated impulse speed.For water tank type waveform generator by piston pressurized water, water high speed consumes impact energy by damping hole, and generates customization waveform.To obtain various customization waveforms, need to design a kind of a kind of waveform generator that discharge area changes in due course as stroke changes.The present invention forms strip-shaped hole, water tank discharge area reduces as stroke increases, to generate the waveform of customization by installing cover board on water tank.By adjusting the shape of cover board, the number of cover board can adjust waveform, in addition can punch and is finely adjusted to waveform on the cover board.
Description
Technical field
The invention belongs to structural impact experimental rigs to develop field, mainly using in large-tonnage impact test, generate various
The surge waveform of customization.
Background technology
Aircraft emergency landing, during completing various air maneuvers etc., aircraft fuselage structure intensity large-scale airborne is set
It standby intensity and is tethered at reliability etc. and subjects harsh test, it is necessary to carry out ground simulation impact test verification.Impact examination
Test the surge waveform for needing to apply various customizations to testpieces.Traditional waveshape generating device includes that rubber, spring, foam etc. are more
Kind pattern.Rubber type waveshape generating device stroke is limited, and the maximum impact force that spring, foam type waveshape generating device generate
It is limited, large-tonnage impact test demand cannot be met, therefore have developed a kind of customizable wave suitable for large-tonnage impact test
The water tank type waveshape generating device of shape.
Invention content
1) goal of the invention
To meet in large-tonnage impact test, various customization surge waveforms are applied to testpieces.
2) inventive technique solution
Impact test process is after testpieces obtains rated impulse speed, to hit waveshape generating device, waveshape generating device
Impact energy is absorbed, and generates the waveform of customization.Water tank type waveshape generating device passes through damping by piston pressurized water, water high speed
Hole consumes impact energy, and generates customization waveform.To obtain various customization waveforms, need to design a kind of discharge area with stroke
A kind of waveshape generating device for changing and changing in due course.The present invention forms strip-shaped hole, water tank mistake by installing cover board on water tank
Water area reduces as stroke increases, to generate the waveform of customization.By adjusting the shape of cover board, the number of cover board is adjustable
In addition whole waveform can be punched and is finely adjusted to waveform on the cover board.
3) advantages of the present invention
It is an advantage of the invention that：The waveshape generating device fills by adjusting the adjustment water tank such as shape, number of cover board
The discharge area set, and discharge area changes in due course with stroke, therefore the adjustable range of waveform is big；Additionally by the cover board
Trepanning can be finely adjusted waveform.The water tank waveshape generating device can also make acceptor of energy and buffer uses.
4) main innovation point of the invention
The water tank waveshape generating device design key that customization waveform can be generated is to design a kind of discharge area with stroke
Variation and the set of device of timely adjustment, the present invention it is innovative case lid replaces with to variously-shaped cover board, between cover board
Gap is exactly the water damping hole excessively of generating means, therefore discharge area, during piston compresses, area constantly reduces.Pass through
Shape, number and the size for adjusting cover board, can customize various waveforms.And aperture is opened on the cover board, customization waveform is carried out micro-
It adjusts.
5) secondary innovative point of the invention
Waveshape generating device guidance system by compositions such as the axle sleeves of guide rod, water tank piston rod entrance on babinet,
Ensure piston not clamping stagnation during the motion.

Specific implementation mode
The water tank type waveshape generating device of the present invention includes piston (1), piston rod, crash panel, stripe board, babinet；Bar shaped
Plate is bolted on babinet, and crash panel is spirally connected with piston rod one end, the piston rod other end be deep into babinet and with work
Plug connection, piston is plate and can be moved back and forth in babinet, has square aperture region on the front side wall of babinet, in side
Shape open area is equipped with multiple stripe boards, and there are gaps between each stripe board, can be by adjusting the installation position of stripe board
Set/width or quantity adjusts the size in the gap；It can change waveform by the size in the gap and the formation of piston
Peak value and pulsewidth；Wherein, blind-mate between the upper surface of piston and the lower face of stripe board.
Specifically for：Cabinet wall is welded with guide rod on face, which can play the guiding role to piston.
