Abstract
A non-linear vibration damper used for transporting large precise optical instrument is composed of base, pallet of instrument, the several rows of supporting springs between base and pallet, and several pairs of horizontal tensional springs between the pallet and the vertical walls of base.
Description
Technical field
The invention belongs to traffic and transport field, relate to the shock attenuation unit that is used for transportation, specifically a kind of nonlinear vibration reduction device that is used for the transportation of large-scale precision optical instrument.
Technical background
Bottom support formula shock attenuation unit is adopted in the transportation of large-scale precision optical instrument cushion packaging at present more.This shock attenuation unit is made up of base, screw mandrel, spring.The bottom of instrument is supported with spring, earlier the bottom of instrument is fixed by the spring on the base; Hold out against instrument with screw mandrel on the horizontal direction, prevent the instrument rollover.This shock attenuation unit only plays damping of vibrations in vertical direction, and its spring vibration satisfies Hook's law, so the vibration damping form of this bottom support formula shock attenuation unit is linear vibration damping.
In the railway transportation, require the resonant frequency of linear support type spring damper to be lower than 4Hz, concerning large-scale precision optical instrument, the spring height will be done very greatly.The packing external form height dimension of large-scale precision optical instrument often will surpass the shipping height restriction like this.To select haulway in transit, will constantly measure the position of packing chest in car simultaneously, prevent that packing chest is because of lateral deviation and extraneous scratching.Secondly because horizontal direction holds out against instrument by the screw mandrel wooden unit, to lean on escort personnel constantly to tighten screw mandrel in transit, guarantee that instrument do not turn on one's side with instrument.
The problems referred to above of Hookean spring support type shock attenuation unit have increased unreliability for the transportation of large-scale precision optical instrument.Must monitor screw mandrel by escort personnel in the transportation, will tighten screw mandrel when loosening.Therefore, this transportation shock attenuation unit uses very inconvenient, and equipment component is prone to problem in transit, brings bigger economic loss sometimes.
Summary of the invention
In order to solve spring excessive height of the prior art, the technical matters that screw mandrel need constantly be tightened in the process of transportation the invention provides a kind of nonlinear vibration reduction device that is used for large-scale optical precision instrument transportation simultaneously.The bottom of instrument adopts support spring to support, and replaces screw mandrel to hold out against instrument with holding out against spring in the horizontal direction.
The present invention is by base bottom support spring, and laterally and tightly propped spring is formed.Support spring in a row is installed on base, is used for the bottom supporting of instrument, adjust the arrangement of support spring and the quantity of every row's support spring according to the shape of institute support instrument bottom and the specification of spring; In the horizontal direction, distribution is many laterally withstands or strains instrument to holding out against spring.The double-type spring that holds out against preferably on same plane, and is on the straight line on two relative sides.
In order to increase effectiveness in vibration suppression, make the large-scale instrument vibration damping even, be installed in the support spring on the base and hold out against spring and be symmetrically distributed.
The present invention is in the process of instrument transportation, and instrument vibrates in vertical direction by the support spring on the base and carries out vibration damping, and instrument vibrates in the horizontal direction by the spring that holds out against on the horizontal direction and carries out vibration damping.The combined action of vertical and horizontal both direction spring realizes instrument integral body vibration damping purpose in transportation.
Elastic deformation takes place in vertical direction and horizontal direction respectively in support spring of the present invention and hold out against spring under state of kinematic motion simultaneously, and it does not satisfy Hook's law, so vibration damping form of the present invention is a nonlinear vibration reduction.
With the train transportation is that example can prove that the present invention is better than existing linear shock attenuation unit.Contrast linear shock attenuation unit, if the intrinsic frequency f n of linear shock attenuation unit is 4.8HZ, distortion δ m was 10mm when train normally moved, and can obtain the minimum 507.2mm of being of base spring height.Distortion δ m still was 10mm when same train normally moved, and natural frequency fn0 of the present invention is 4HZ, and the height of support spring of the present invention is 240mm as calculated.The height of linear shock absorption device spring is that a times of support spring height of the present invention also wants many.In addition, use the present invention to transport large-scale optical precision instrument, X, Z to rigidity be Y to 1/3 of rigidity, so both little to the oscillation frequency influence to X, Z, on the Y direction, play the favorable damping effect again.
Description of drawings
Fig. 1 is a structural representation of the present invention, also is the specification digest accompanying drawing.1 is base among the figure, and 2 is support spring, and 3 for holding out against spring, and 4 is base side wall, and 5 is the base bottom.
Fig. 2 is one embodiment of the present invention scheme drawing.
Fig. 3 is one embodiment of the present invention scheme drawing.
The specific embodiment
It is circular that the bottom of large-scale longitude and latitude is generally, and for the instrument of rounded bottom, support spring 2 adopts three rows' supporting way, and the arrangement of support spring 2 as shown in Figure 2.At base 1 three row's support springs, 2, three row's support springs 2 being installed arranges with equilateral triangle.
For the large-scale optical precision instrument of plinth, when using the present invention to transport, support spring 2 preferably adopts more than three rows.Fig. 3 is that four row's support springs 2 are arranged scheme drawing, and four row's support springs 2 are arranged for square.
