Description
Technical field
The present invention relates to eliminate shell vibrating device, it is related to eliminate the device of stiff case vibrations, especially one kind has
Eliminate the vibrations cancellation element and addition type experimental analysis device of stiff case vibration function.
Background technology
The essential reason that the vibrations of some stiff case devices are produced is that enclosure interior or have the relation of being fixedly connected therewith
Outside vibration source is close with the intrinsic frequency of housing, so as to produce resonance, housing is produced significant shock.Such as vehicle complete vehicle
Damping is tested, and often carries out additives experiment in housing diverse location, needs to be added with which position for determining shell structure
Strong but to be tested there is presently no special device with eliminating vibrations, the time of consuming is more long, there is provided reference frame not
It is enough accurate.
The content of the invention
The purpose of the present invention is directed to above-mentioned situation, there is provided a kind of to be eliminated with the vibrations for eliminating stiff case vibration function
Device and addition type experimental analysis device, this installation cost are low, can rapidly change the intrinsic frequency of stiff case so that rigidity
Housing is not susceptible to resonance with the existing vibration source of machine in housing, so that stiff case vibrations are eliminated rapidly, and offer is judged
Which strengthened eliminating the reference frame of vibrations in the position to rigid housing structures.
Realizing the technical scheme of the object of the invention is：
A kind of vibrations cancellation element with elimination stiff case vibration function, including
Flexure strip, the flexure strip is curved, and flexure strip is two；
Elastic contact head, the elastic contact head is arranged on the arcuate projection of flexure strip；
Connecting rod, the connecting rod is two；
Two flexure strips and two connecting rods form detachable arc square bearer, and two of which connecting rod is practised physiognomy
Right, two flexure strips are facing.
Two elastic contact heads are one group, and it is corresponding that two elastic contact heads in every group are separately positioned on two flexure strips
Position on.
The elastic contact head is 1-10 groups, preferably 5 groups.
Impartial point of the elastic contact head is arranged on flexure strip.
It is a kind of with the addition type experimental analysis device for eliminating stiff case vibration function, its structure is with above-mentioned with disappearing
Except the vibrations cancellation element of stiff case vibration function is identical.
One housing can resonate under several frequencies, machine is worked under different conditions, that is, housing institute
The various possible vibration source frequency at place, is attached to positions different on housing, most with multiple this vibrations cancellation elements respectively
Cause that shell vibrating is obviously reduced eventually, so as to which position for drawing shell structure needs to be strengthened, needed when housing is manufactured
Strengthened, added casting amount etc., this intrinsic frequency for strengthening changing housing so that it is with the existing vibration source of housing inner machine not
Easily resonate, so as to eliminate the seismism of housing.
The present apparatus is applied to the stronger housing of rigidity and makees scientific experiment, for analysis shell structure produces the position of resonance to provide
Intuitively reference frame.
This vibrations cancellation element and addition type experimental analysis installation cost are low, can rapidly change the intrinsic frequency of stiff case
Rate so that stiff case is not susceptible to resonance with the existing vibration source of machine in housing, and vibrations cancellation element eliminates rapidly rigid crust
Body shakes, and addition type experimental analysis device provides and judges which position of rigid housing structures is strengthened eliminating vibrations
Reference frame.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment 1 and embodiment 2.
