The damping spring piece is characterized in that the damping spring piece is composed of a straight-line section and a circular arc section, the section of the damping spring piece is a rectangle uniform section, and the length l of the straight-line section of a structure parameter of the damping spring piece is 7-9 mm; the radian R of the circular arc section is 165-170 degrees, the circular arc semidiameter r of the circular arc section is 7-8 mm, and a placing tilt angle a of the damping spring piece is 36-37 degrees; and the optimum shape structural parameter of the damping spring piece of the minitype oscillator of the circular arc section is that the length l of the straight-line section is 8 mm, the radian R of the circular arc section is 168.7 degrees, the semidiameter r of the circular arc section is 7.8 mm and the placing tilt angle a of the damping spring piece is 36.87 degrees. The damping spring piece provided by the utility model patent has the beneficial effects that the structure of the damping spring piece designed by the utility model patent meets the rigidity of the oscillator, and meanwhile, the free-running frequency of the structure is reduced; and the free-running frequency of the structure is reduced to 14 Hz from the original 23.5 HZ, and the maximum displacement of the structure does not exceed 3 mm on a vertical working face.
Description
Technical field
A kind of spring sheet of the utility model, particularly a kind of vibration insulating system spring sheet that is used for microoscillator.
Background technique
Microoscillator requires relatively harsher to working environment, be placed on merely in the electric cabinet, under dynamic excitation, is prone to judder takes place, and influences the proper functioning of oscillator.Traditional chip architecture of the spring is formed through arc transition by two sections straightways; By illustrated in figures 1 and 2, natural frequency is higher when microoscillator is used, and under high-frequency signal injection, is prone to resonate; And a little less than the chip architecture of the spring rigidity, can not satisfy the rigidity requirement of microoscillator.
Summary of the invention
The purpose of the utility model provides and had a kind ofly not only satisfied structural rigidity and require but also avoid taking place resonance shock-absorbing spring sheet.
For realizing above-mentioned purpose, the technological scheme of the utility model is a kind of shock-absorbing spring sheet of microoscillator; Be characterized in; This shock-absorbing spring sheet is made up of a straightway and arc section, and its cross section is a square equal cross-section, said shock-absorbing spring chip architecture parameter length of straigh line
lBe 7～9mm, the arc section radian
RBe 165～170 °, the radius of arc of arc section
rBe 7～8mm, the shock-absorbing spring sheet is put the inclination angle
aIt is 36～37 °.
The shock-absorbing spring sheet optimum shape structural parameter of microoscillator are: length of straigh line
lBe 8mm, the arc section radian
RBe 168.7 °, the arc section radius
rFor 7.8mm and shock-absorbing spring sheet are put the inclination angle
aIt is 36.87 °.
The beneficial effect of patent of the present invention is: the shock-absorbing spring chip architecture that patent of the present invention designed in the rigidity that satisfies oscillator simultaneously; Can reduce the natural frequency of structure again; Structural natural frequencies is reduced to 14Hz by original 23.5Hz, and the maximum displacement of structure on vertical working surface is no more than 3mm.

Fig. 4 is the chip architecture of the spring schematic representation of the utility model vibration insulating system.
Embodiment
Below in conjunction with accompanying drawing and enforcement, be example with the shock-absorbing spring chip architecture, the utility model is further described.The utility model is that the top straightway that original structure is shown in Figure 1 is designed to circular arc, and is as shown in Figure 3.Its structure shape is mainly by the arc section radian
R, radius
rDecision, another straightway is constant.By shown in Figure 3, the shock-absorbing spring sheet of the utility model microoscillator is characterized in, this shock-absorbing spring sheet is made up of length of straigh line a straightway and arc section
lBe 7～9mm, the arc section radian
RBe 165～170 °, the radius of arc of arc section
rBe 7～8mm, the shock-absorbing spring sheet is put the inclination angle
aIt is 36～37 °.Shown in Figure 2, the vibration insulating system of oscillator is made up of the copper spring sheet 2 and pallet 1 two-part in four same materials and cross section.The spring sheet lower end is fixed on electricity cashier's office in a shop, and the upper end holds up a platform, and oscillator is fixed on the platform; Because the quality of spring sheet itself is very little with respect to the pallet quality, the rigidity of vibration insulating system and natural frequency are mainly by the structures shape of single spring sheet.Utilize CAE software optistruct to carry out Shape optimization, obtain the optimum shape structure through Shape optimization: length
l 0=8mm radian
R 0=168.7 ° of radiuses
r 0=7.8mm and inclination angle
a 0=36.87 °.Result to after optimizing carries out same constraint and loading, reduces to 14Hz through the natural frequency of calculating vibration insulating system by original 23.5Hz, has reduced by 40%; And the maximum displacement of structure on vertical working surface is no more than 3mm, required rigidity when having guaranteed arrangement works.
