Abstract
A kind of pulse exciting method and electromagnetic pulse exciting instrument.The present invention relates to the exciting technology and the equipment of physical construction dynamic analysis.Exempt to use large power amplifier, directly produce instantaneous large power, electrically pulse with the big electric capacity of high pressure and go exciting physical construction, specifically can realize by electromagnetic pulse exciting instrument.This instrument is made up of electric pulse generator, stabilized voltage supply, response measurement part, impulsive force waveform output part and sine excitation robot scaling equipment, and volume is little, and is in light weight, and transient pulse power is big.
Use this method and this instrument excitation physical construction power big, fast and convenient, waveform stabilization, repeatable accuracy height.
Description
The invention belongs to the pulse excitation technology and the equipment of physical construction dynamic analysis.
In the prior art, thus related pulse exciting method is all amplified incentive object by power amplifier with pulse signal with a pulse signal generator.The pulse signal power that general pulse signal generator sends is very little, and necessary power amplifier volume is big, and deal is heavy, carries inconvenience, and the signal of output is continuous.Birmingham, GBR university in 1979 opens emerging standard (machinery system of Beijing Post and Telecommunications College) by Chinese scholar and utilizes scholar Fu HP5451C analyser to produce the half-sine pulse signal through B﹠amp under S.A.Tobias professor and M.M.Sadek Bo Shi guidance; The K2708 power amplifier has carried out the pulse exciting test.Nineteen eighty-two, University Of Chongqing's machinery was that continue usefulness micropulsers such as Yao and power amplifier of thunder tested small-sized free beam.These two tests all are to use power amplifier.
The objective of the invention is: for existing enough power drive physical construction in the production scene, waveform stabilization is provided, the impulsive force signal that repeatable accuracy is high, efficient quick, equipment advantage simple, with low cost is arranged again, vibration test is oversimplified, consider that with suitable equipment replacement power amplifier instantaneous large power, electrically pulse directly takes place, and to go exciting physical construction be with practical value, and then developed a kind of electromagnetic pulse exciting instrument.
Electromagnetic pulse exciting instrument is by stabilized voltage supply, response measurement partly, the output of impulsive force waveform partly, sine excitation robot scaling equipment and electric pulse generator are formed.Except that electric pulse generator, all parts all can utilize existing procucts to be electrically connected.Therefore the core of this instrument partly is an electric pulse generator, and it contains the big electric capacity that can produce the high strength electric pulse, can produce instantaneous high-powerly, can substitute the power amplifier of amplification continuous signal.The high-power power that is meant described here is more than 1000 watts.
Accompanying drawing has provided one embodiment of the present of invention.
Fig. 1 is the test macro block diagram that utilizes the direct exciting physical construction of electromagnetic pulse exciting instrument, and exciting object wherein can be the C6140 lathe.
Partly provided the formation block diagram of electromagnetic pulse exciting instrument in Fig. 2 dot-and-dash line, integrating amplifier wherein is an impulsive force waveform output part, and voltage amplifier and impedance transformer are the response measurement parts.
Fig. 3,4,5 and 6 has provided the starting or stopping control circuit in the electric pulse generator on Fig. 2 respectively, automatically continuous impulse control circuit, electric pulse generator main circuit and counting display circuit.Contain the big electric capacity 4 μ f/1000V of high pressure in the electric pulse generator main circuit of Fig. 5.
An electromagnetic pulse exciting instrument, its function can replace low frequency generator, high power amplifier at least, digital voltmeter, D.C. regulated power supply, six instruments such as " power " signal secondary meter and " response " signal secondary meter are simplified excitational equipment greatly, and volume is little, in light weight, low in energy consumption, instantaneous high-power more than 1000 watts, fast efficient, be particularly suitable for the production scene and carry out vibration test.
