Technical field
The present invention relates to a kind of caliberating device of cannon breech pressure survey sensor, relate in particular to the dynamic calibration apparatus of cannon breech pressure survey sensor.
Background technology
In cannon research, the measurement of cannon breech pressure is to weigh the shooting characteristic of cannon and an important indicator of ballistic characteristics, and in development, production, maintenance and the Performance Testing process of projectile weapon, gun pressure pressure survey is also most important and requisite.Pressure survey in general cannon thorax is that pressure transducer is arranged on the tail end wall of cannon bullet ammunition portion, when transmitting, directly measures the pressure in cannon thorax by the output of pressure transducer.The scaling method of above-mentioned pressure transducer is generally to adopt a kind of static pressure to demarcate or half dynamic calibrating method (with pressure device, pressure transducer being bestowed to static pressure or low speed impact), the momentary status of this demarcation state and Canon launching bullet differs greatly, therefore, stated accuracy is poor, thereby causes the measuring accuracy of cannon breech pressure to reduce.
Summary of the invention
The object of the invention is for the deficiency in prior art, a kind of dynamic calibration apparatus of cannon breech pressure survey sensor is provided, to improve the stated accuracy of cannon breech pressure survey sensor, finally improve the measuring accuracy of cannon breech pressure.
For achieving the above object, technical scheme of the present invention is as follows:
It has a shock supercharger that air bubble is relative with this air bubble with, a standard pressure transducer and one are housed on described shock supercharger by nominal pressure sensor, described standard pressure transducer and being joined by a suitable device A of tune and suitable device B and a data processor adjusted respectively by the signal output part of nominal pressure sensor.
Further improved technical scheme of the present invention is as follows:
Described shock supercharger has a cylinder body, this cylinder body front portion is a low pressure (LP) cylinder, be communicated with the high pressure cylinder of a undergauge at the afterbody of this low pressure (LP) cylinder, in described low pressure (LP) cylinder, be provided with a pair of first piston facing each other and the second piston, between described first piston and the second piston, be provided with the first hydraulic oil, the front bulkhead of low pressure (LP) cylinder is stretched out in the piston rod packing of described first piston, and be connected with a crash panel, the piston rod of described the second piston oppositely stretches in high pressure cylinder, and be connected with the 3rd piston that is arranged in high pressure cylinder, between the tail end wall of described high pressure cylinder and the 3rd piston, be provided with the second hydraulic oil, described standard pressure transducer and being arranged on the tail end wall of described high pressure cylinder by its mount pad by nominal pressure sensor.
Beneficial effect of the present invention is as follows:
One, this caliberating device has been simulated the dynamic of Canon launching, shock supercharger of projectile impact of getting with air bubble, clash into the standard pressure transducer on supercharger and experienced this flashy high-speed impact pressure by nominal pressure sensor simultaneously with being arranged on, thereby record the pressure curve of two pressure transducers, realized the demarcation of dynamical state lower pressure sensor.This dynamic calibration has improved the stated accuracy of cannon breech pressure survey sensor greatly, and this device also has feature easy to use, work efficiency is high.
Two, the shock supercharger that the present invention adopts is at compressed liquid (hydraulic oil) pressure or pressure constant in the situation that, change lifting surface area, make pressure become large, thereby can make the shock pressure of bullet improve tens times, not only meet well the supercharging requirement of calibration measurements, but also need not any energy, be a kind of energy-conservation supercharging device.
Describe with reference to the accompanying drawings structure of the present invention and principle of work below in detail.
Brief description of the drawings
Accompanying drawing is one-piece construction schematic diagram of the present invention.
Embodiment
Referring to accompanying drawing, it has the shock supercharger (Q) that an air bubble (P) is relative with this air bubble with, a standard pressure transducer (1) and one are housed on described shock supercharger by nominal pressure sensor (2), described standard pressure transducer and being joined by a suitable device A of tune and suitable device B and a data processor adjusted respectively by the signal output part of nominal pressure sensor.Described air bubble is mature technology, and it generally comprises gun tube (11), hyperbaric chamber (12), pressure control desk (13) and source of the gas (14).When transmitting, bullet (10) is put into gun tube, then by pressure control desk, Projectile Motion speed is set, and according to the air pressure in this setup control hyperbaric chamber, make it produce instantaneous pressure, penetrate with the movement velocity of setting thereby promote bullet.
Again referring to accompanying drawing, described shock supercharger has a cylinder body (5), this cylinder body front portion is a low pressure (LP) cylinder, be communicated with the high pressure cylinder of a undergauge at the afterbody of this low pressure (LP) cylinder, in described low pressure (LP) cylinder, be provided with a pair of first piston facing each other (8) and the second piston (6), between described first piston and the second piston, be provided with the first hydraulic oil (7), the front bulkhead of low pressure (LP) cylinder is stretched out in the piston rod packing of described first piston (8), and be connected with a crash panel (9), the piston rod of described the second piston oppositely stretches in high pressure cylinder, and be connected with the 3rd piston (4) that is arranged in high pressure cylinder, between the tail end wall of described high pressure cylinder and the 3rd piston, be provided with the second hydraulic oil (3), described standard pressure transducer (1) and being arranged on the tail end wall of described high pressure cylinder by its mount pad by nominal pressure sensor (2).In the time that bullet (10) strikes crash panel (9), crash panel is delivered to projectile impact pressure on the second piston (6) by first piston (8) and the first hydraulic oil, and then it is upper to be delivered to the 3rd piston (4) by the piston rod of the second piston again, be finally delivered to standard pressure transducer (1) by the second hydraulic oil (3) and by nominal pressure sensor (2).In this course, the first hydraulic oil (7) is directly bearing the shock pressure of bullet, in the situation that this shock pressure is constant, due to reducing of the 3rd piston area, make the pressure that the second hydraulic oil (3) bears become large, this pressure action is on two pressure transducers, in the constant situation of the second hydraulic oil pressure, because the compression area of two sensors is more much smaller than the 3rd piston, pressure is increased again, thereby realized two-step supercharging, utilized Pascal's energy to keep homeostasis rule and change, it can improve tens times by the shock pressure of bullet.This shock supercharger is both energy-conservation, and supercharging amplitude is high again.Because its supercharging amplitude is high, can also alleviate the transmitting pressure of air bubble, thereby reduce whole device use cost.
The whole course of work of this device is: penetrate bullet (10) by air bubble (P) with the movement velocity of setting, projectile impact is clashing on supercharger (Q), and by clashing into that the supercharging of supercharger (Q) is delivered to described standard pressure transducer (1) and by nominal pressure sensor (2), after these two pressure transducer pressurizeds, export respectively two-way pulse signal, this two-way pulse signal is sent into data processor after amplifying adjustment by the signal of suitable tune device A and suitable tune device B respectively, data processor is processed this two-way pressure signal, show that a normal pressure curve and one are by nominal pressure curve, and obtain by the pressure calibration coefficient of nominal pressure sensor (2) according to these two tracing analysiss.
