Description
Technical field
The utility model relates to the impact test apparatus of environmental mechanics test, and particularly a kind of band adds the shock table of energy device.
Background technology
Shock table mainly is to be used for analog equipment to suffer the testing equipment of shock environment in use, loading and unloading or transportation, to determine the adaptability of this product to various impulsive forces, and evaluate the integrity of its structure, for the quality of examining this product provides rational foundation.Therefore, be widely used in fields such as weaponry, electromechanical equipment, instrument and meter, household electrical appliance.
The stage body structure of shock table is mainly the bottom and is provided with a base, the central authorities of base are provided with fixed station, impact damper or waveform generator are housed on the fixed station table top, the base both sides are respectively equipped with a guidepost, be provided with the test table top between two guideposts, test table top and two guideposts are slidingly connected, and can be along the upper and lower slip of guidepost, test table top bottom is provided with ram hammer over against the position of fixed station, and the both sides of two guideposts are respectively equipped with hoisting gear.
During test, test specimen is fixed on the test table top, will test table top and test specimen by hoisting gear and after guidepost rises to certain altitude h, discharge suddenly, make test specimen and test table top and freely fall on waveform generator together.When the test table top falls when touching waveform generator, it falls speed and is
The testing table motion that faces down is obstructed, thus produce one opposite to gravity direction high acceleration.Under this acceleration, that tests table top falls velocity variations to zero, and acceleration reaches peak value, and the kinetic energy of test table top is transformed into the deformation energy of waveform generator fully.Afterwards, under the effect of this deformation energy, the bounce-back of test table top is moved upward, its bounce-back speed is cumulative, and backward acceleration reduces, till test table top and waveform generator disengaging, thereby make table top and test specimen be subjected to an acceleration pulse effect, finish impulse test.
The pulse action that test specimen is subjected to is relevant with its suffered backward acceleration, and the value of backward acceleration is by the falling height decision of test table top, the restriction of test platform structure owing to be hit, the limited length of guidepost, the falling height of its test table top can not raise again.How making shock table that bigger impact backward acceleration is arranged, satisfy more testing requirements, is the utility model content of research emphatically.
Summary of the invention
The utility model provide a kind of band add can device shock table, its purpose mainly is to solve because of being subjected to have now the influence of shock table structure, and makes the problem that the backward acceleration of shock table is restricted.Thereby improve the test performance of shock table, satisfy more testing requirements.
For achieving the above object, the technical solution adopted in the utility model is: a kind of band adds the shock table of energy device, comprise two guideposts and the test table top that slides and be provided with along two guideposts, comprise that also one adds the energy device, this adds and can be made of compression spring and spring base cooperation by device, spring base is installed in the top of guidepost, compression spring is set on the guidepost, and be positioned at the test table top the top position, one end of compression spring is fixedlyed connected with spring base, and the other end acts on the test table top for the effect end.
1, in the such scheme, the effect end of corresponding compression spring is provided with a guard ring on the described test table top, and when the test table top promoted, this guard ring can the protection test table top be compressed spring and damages damage by pressure, thereby has guaranteed the attractive in appearance and precision of shock table.
2, in the such scheme, described spring base is connected through bolt with the top of guidepost.
3, in the such scheme, an end of described compression spring is fixed in the spring base, and this spring base is located at the guidepost top, and its shape is not limit.This spring base helps the store energy of compression spring, has avoided compression spring simultaneously when energy discharges, and disorderly wears up and down along guidepost and influences test accuracy.
Principle of work of the present utility model is: because the influence of the testing table self structure that is hit, the hoisting depth of test table top is restricted, the utility model is a sheathed compression spring on the guidepost of shock table, this compression spring is stored energy mechanism, because the peak acceleration that the impact energy decision of test table top can realize, when the test table top is raised, compression spring is compressed, thereby carry out energy storage, when the test table top rose to certain altitude release, compression spring also discharged elastic potential energy, thereby increased the impact energy of test table top, make it have bigger backward acceleration, realize the testing requirements of peak acceleration.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the utility model sheathed compression spring on guidepost, the one end is fixedly arranged in the spring base on guidepost top, the other end acts on the test table top for the effect end, make this shock table when work, can increase the impact energy of test table top by the elastic potential energy that compression spring stores, make it have bigger backward acceleration, realize the testing requirements of peak acceleration, improve the test performance of shock table, satisfied more testing requirements.
2, owing to the end of the utility model with compression spring is fixed in the spring base on guidepost top, thereby help the store energy of compression spring, avoided compression spring simultaneously when energy discharges, disorderly wear the generation of phenomenon along guidepost up and down.
3, because the utility model is being provided with a guard ring on the position of corresponding compression spring on the test table top, when the test table top promoted, this guard ring can the protection test table top be compressed spring and damages damage by pressure, thereby has guaranteed the attractive in appearance and precision of shock table.
