Description
The present invention relates to information-measuring technique, more precisely relate to the dynamic indicator of indicating various physical parameter of awaiting testing specimen.
The most successful part of the present invention is under industrial condition, can be used for many strength characteristicies of various materials are carried out quality inspection, for example their Hardness Surveillance.
In the practice of various material test, particularly when check large-size components and complex-shaped goods, just produce the problem that their characteristic is tested fast, at first be their hardness and with its result's of numeral demonstration problem.
The known test agent physical quantity dynamic indicator (D.Jeeb. " Neues dynamishes Massverfahren Eur Haertepr ü fung metullischer Weekstoffe " that treats, " Microtecnic ", 1979, NO.2, (11,13-15,17),) comprise that the percussion device with tup, this tup have and the pressure head for the treatment of the test agent surface interaction; Tup motion rate sensor with percussion device tup mechanical connection; The signal adaptation amplifier, its input end and tup motion rate sensor are electrically connected; The note meaning circuit that is electrically connected with the signal adaptation amplifier; A/D converter is electrically connected with the signal adaptation amplifier and an one input end is connected the output terminal of memory circuit; Clock pulse forms device, and its output termination is to another input end of A/D converter: form counter that device is electrically connected and form the display device that device links to each other with counter with clock pulse with clock pulse.Also with a memory circuit, the input termination that it connects with another memory circuit is to the output terminal of adaptive amplifier for this indicator, and output terminal then connects another input end to A/D converter; And logic control circuit, its input termination is to counter output, and output terminal then connects another input end to A/D converter.But the relevant physical quantity (hardness) in this dynamic indicator shown in the indication is to determine according to the relation of two information parameters, for example, in order to determine to treat the hardness of test agent, will be according to two kinds of speed of tup motion; Being tup contact the speed (spacing also is about 1 millimeter) that preceding speed (about 1 millimeter of its spacing) and tup rebound from treating the test agent surface with treating the test agent surface, so, will produce friction force and gravitational influence, and cause problem that reduce to measure the degree of accuracy for the treatment of test agent physical quantity (hardness).
In addition, in above-mentioned dynamic indicator, treat that the elastic property of test agent exerts an influence to its physical quantity (hardness) assay, thereby must carry out preliminary election that this point itself will reduce the validity of check too to the module of elasticity of sample.
In above-mentioned dynamic indicator, can only adopt spherical pressure head, this point can dwindle the envelop of function of dynamic indicator equally.
Meanwhile, in this dynamic indicator, adopt spherical pressure head requirement percussion device strictly to keep the upright position, when departing from the upright position, just need introduce modified value in treating test agent physical quantity testing result, this has also reduced degree of accuracy and the validity for the treatment of that test agent detects.
As the task that basis of the present invention proposed is to make a kind of dynamic indicator of measuring the sample physical quantity, make it have some adapters, these adapters can be finished the measurement of various information parameters in treating the test agent loading procedure, treat that with elimination the elastic force of test agent treats the influence of test agent physical quantity assay to these, satisfy to adopt the pressure head of various types and treat in the unspecified angle hammering under the situation on test agent surface, can both record the various physical quantitys of this sample.
This is by reaching to get off, and treats that test agent physical quantity dynamic indicator comprises the percussion device of the tup with band pressure head, pressure head with treat the test agent surface interaction; The tup motion rate sensor that links to each other with the tup machinery of percussion device; The signal adaptation amplifier, its input end and the tup motion rate sensor is electric joins; The memory system that is electrically connected with the signal adaptation amplifier; A/D converter, be electrically connected with the signal adaptation amplifier and an one input termination to the output terminal of memory circuit; Clock pulse forms device, and its output termination is to another input end of A/D converter; Form the counter that device is electrically connected with clock pulse; And the display that links to each other with joint Chinese tallow tree pulse shaper with counter, according to the present invention, additionally comprise and set up measuring appliance when treating between the test agent loading, its input termination is to the output terminal of signal adaptation amplifier, input end from termination to memory system that export, another output terminal then connects another input end to A/D converter, also has an output terminal then to connect input end to counter; And treat test agent physical quantity magnitude calculation unit, its each input end correspondingly connects to counter, A/D converter and each output terminal joint Chinese tallow tree pulse shaper, and its output termination is to the input end of display, clock pulse simultaneously forms the input end of the output termination of device to counter.
Do suiting like this, in treating test agent physical quantity dynamic indicator, make and treat that test agent load time measuring appliance comprises " RS " trigger, its output terminal is an output terminal treating test agent load time measuring appliance; The peaked steady arm of tup motion acceleration pulse, its output terminal treat that promptly another output terminal of test agent load time measuring appliance receives " R " input end of " RS " trigger; And tup motion acceleration pulse initial value steady arm, an one output termination then is another output terminal for the treatment of test agent load time measuring appliance to " S " of " RS " trigger input end, another output terminal, with the joining input end of tup motion impulse maximal value steady arm input end then be to treat test agent load time measuring appliance input end.
It is desirable doing like this, makes to treat in the test agent physical quantity dynamic indicator, and the tup motion acceleration pulse maximal value steady arm for the treatment of test agent load time measuring appliance comprises the comparer and the differentiator of mutual series connection.
Reasonably the practice is, make and treat in the test agent physical quantity dynamic indicator, the tup motion acceleration pulse initial value steady arm for the treatment of test agent load time measuring appliance comprises the basic differentiator (its output terminal is the output terminal of tup motion acceleration pulse initial value steady arm) of mutual series connection, comparer and additional differentiator.
The present invention can virtually completely get rid of friction and gravitational influence in tup and the measurement for the treatment of to finish in the test agent contact process many information parameters, has so just improved the degree of accuracy of check simultaneously.
Outside the ratio, the present invention has got rid of the recovery stage of elastic deformation in the information parameter measuring process, makes the influence for the treatment of the test agent elastic property drop to minimum, and this has just improved the validity for the treatment of the test agent check simultaneously.
When using spherical pressure head, the device that is provided is when testing, also allow to adopt cone and pyramid pressure head, this has just expanded the envelop of function of indicator and can reduce clashing into the requirement of energy stability, also can reduce the requirement that the tup bump is kept strict verticality simultaneously.
