Description
Technical field
The present invention relates to the electric vibration testing device in environmental mechanics test, be specifically related to a kind of electric vibration testing device with replacing formula horizontal sliding table.
Background technology
In vibration test technical field, when test specimen need carry out the vibration of horizontal direction, need configuration level slide unit, to meet the testing requirements of horizontal direction.Traditionally, be all that an electric vibration table and a horizontal sliding table are arranged on and on same support, form the holistic electric vibration testing device of making horizontal direction vibration test and be sold to user.During test, test specimen is installed on the table top of horizontal sliding table, and the moving-coil of electric vibration table and the table top of horizontal sliding table are rigidly connected by connector, by electric vibration table drive horizontal sliding table table top and on test specimen vibrate.
From Newton second law (acceleration law):, in the certain situation of thrust, m value is less, and accekeration a is larger; Otherwise m value is larger, accekeration a is less.And in actual test conditions, the accekeration that small specimen need to vibrate is conventionally larger, the accekeration that large test specimen need to vibrate is less.So for the little test specimen of specification, need the little horizontal sliding table that quality is light, for the large test specimen of specification, need large horizontal sliding table to meet testing requirements.When the test specimen specification used as user is different with test index, the shaketalle test device that configures single horizontal sliding table cannot meet testing requirements completely.Conventionally for different test specimen specifications and test index, buy a plurality of horizontal vibration test units, not only user cost increases, and shaking table utilization factor is low, causes waste.
In order to meet user's multiple test specimen specification and the requirement of test index, existing technology is the vibration testing device that single shaking table coordinates two horizontal sliding tables, concrete structure is referring to disclosed CN201307057Y patent of invention on September 9th, 2009, this kind of vibration testing device primary structure as shown in Figure 1, comprise the shaking table 2 and the horizontal sliding table that are arranged on support 1, one horizontal sliding table (being large specification horizontal sliding table 3 and small dimension horizontal sliding table 4) is respectively set at shaking table 2 two ends, and shaking table 2 and horizontal sliding table are arranged on same support 1, when by shaking table 2 stage bodies around horizontal axis when rotation perpendicular to shaking table 2 stage body axis, its moving-coil angle be 180 ° two horizontal levels respectively with two horizontal sliding tables 3, 4 level connection joints.During work, need will vibrate stage body to required horizontal sliding table direction rotation to horizontal level, and be connected by connector with horizontal sliding table, carry out vibration test.The advantage of this device is to meet two kinds of test specimen specifications and test index, but also has following defect:
(1) while switching horizontal sliding table, the shaking table that need to overturn, relates to the upset of water pipe (water-cooling vibration platform) or airduct (air-cooled shaking table), oil pipe and electric wire, and this blocked operation is very loaded down with trivial details and time-consuming;
(2) support 1 needs to strengthen, and vibrating device floor area increases;
(3) the stage body structure of shaking table 2 need to be changed on the basis of the common stage body structure of shaking table, redesigns.
