Embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～3, the present invention includes: fixed base 1, adjustable strut 2, top cover 3, whorl brace rod 4, space bar 5, last compressing tablet 6, location piece 7, portable connecting groove 8, location nail 9, fixed connection place 10, metal-rubber element 11.Fixed base 1 plays fixation, in the zone 10 on base, is arranged with a large amount of orderly bolts hole, be used for and being connected of fixed reference thing, such as with being connected of ground.Portable connecting groove 8 is zones on the base, and the cross groove of staggered inclination is arranged in this zone, and the groove cross section presents convex shape, in the bottom of convex shape groove, movably nut is arranged, and is used for wanting to be connected with adjustable strut 2.The skeleton part that adjustable strut 2 is these vibration damping equipments; It links to each other with top cover 3 through location piece 7; Play the effect of supporting top cover 3, it is connected the casing frame that has connected to form this vibration damping equipment between them with fixed base 1 through portable connecting groove 8 simultaneously.Place metal-rubber element 11 in the casing frame the inside, on fixed base 1 and top cover 3, insert location nail 9, can the metal-rubber element on top layer be positioned, the metal-rubber element of nexine can be through pushing the location.Because the characteristic that the metal-rubber element can only pressurized can not be drawn; The vibration damping equipment that the metal-rubber element is formed must make that the tension and compression up and down that produce in the vibration processes are stressed to change into the pressure that the metal-rubber element can bear, and this vibration damping equipment also has a very important part---the stressed transform portion of tension and compression.The stressed transform portion of tension and compression is by whorl brace rod 4, space bar 5, and last compressing tablet 6, and metal-rubber element 11 forms, it is as a whole that last compressing tablet 6 connects into whorl brace rod 4 and space bar 5, and it is two-layer about being divided into that metal-rubber element 11 is spaced apart plate 5.
Link to each other with this vibration damping equipment when vibration source passes through whorl brace rod 4, its vibration sees through the stressed transform portion of tension and compression and passes to metal-rubber element 11.For the up-down vibration of individual event, metal-rubber element 11 is satisfying under the situation of applying working condition and can arrange arbitrarily, and this arrangement relates to the simple series parallel connection relation of metal-rubber element.For three-way vibration; Common arrangement mode obviously is weaker than Vertical direction in circumferential effectiveness in vibration suppression; In order to reduce metal-rubber element 11 waste quantitatively; Effectively improve the utilization ratio of metal-rubber element 11, the present invention proposes a kind of novel metal rubber element arrayed mode---convertible cross arrangement, promptly make the upset of the moulding compression face of part metals rubber element it face whorl brace rod 4; The moulding compression face of the metal-rubber element of common arrangement is being faced the top cover direction; The upset signal that is shaped as rectangular solid metal-rubber element is shown in accompanying drawing 2, and the concrete realization of its arrangement is used the circumferential effectiveness in vibration suppression of the raising metal-rubber element that the metal-rubber element of upset can be very big in the part space shown in 135 ° of diagonal line hatches parts in the accompanying drawing 1.
In conjunction with shown in Figure 1; Adjustable strut 2 is connected on the portable connecting groove 8, and lower metal rubber element 11 is placed on the fixed base 1 and arranges, and through location nail 9 it is fixed; The stressed conversion component of tension and compression that whorl brace rod 4, space bar 5, last compressing tablet 6 are formed is placed on the central position; Framework along adjustable strut 2 and the stressed conversion component of tension and compression are formed is placed arrangement upper strata metal-rubber element 11, adds top cover 3 and location nail 9, locatees metal-rubber element 11 positions; Through location piece 7, the structure of whole vibration damping equipment is fixed.
In conjunction with shown in Figure 3; During use; According to the quantity and the arrangement of usage requirement in the operating mode and stressing conditions adjustment metal-rubber element,, secondly fix the position of metal-rubber element 11 through location nail 9 and location piece 7 at first through the size of portable connecting groove 8 these vibration damping equipments of adjustment; Through the position of 10 fixing these vibration damping equipments of the zone on the fixed base 1, vibration source just can see through the purpose that this device reaches vibration damping at last.
Metal-rubber is arranged criterion: metal-rubber array effect depends on series of elements parallel connection effect, number of elements and geometry arrangement form.
Under normal conditions; All elements should be realized with the shop layer; The shop layer is deferred to principle from bottom to top; For guaranteeing the proper functioning of vibration damping equipment, element is that central shaft is symmetrically distributed with whorl brace rod place straight line, and the selection of element form is screened according to making the element arrangements compactness and can being full of the inner prerequisite of vibration damping equipment at last.
For unidirectional up-down vibration requirement, be cutting lines with the space bar, guarantee that the stack effectiveness in vibration suppression of element is symmetrical up and down.
For the requirement of three-dimensional vibration damping, element is satisfying under the above condition, and the above metal-rubber of space bar also will consider to add inverted arrangement, strengthens horizontal effectiveness in vibration suppression, and its quantity changes along with the size of horizontal vibration damping requirement under the prerequisite that satisfies the center symmetry principle.
On the value of series parallel connection form and number of elements; The metal-rubber element adopts generalized M axwell model and broad sense Voigt model; Calculate respectively and adopt the needed metal-rubber number of elements of different series parallel connection effects, satisfying geometry arrangement form and the quantity of confirming element under the condition of above criterion.
For two kinds and above metal-rubber element; The employing modularization is calculated; Confirm the vibration-damping function that every kind of metal-rubber element need be realized, and then confirm respectively the number of elements of each module to make array realize substituting the effectiveness in vibration suppression of single metal rubber shock absorber according to model.
Under the prerequisite that guarantees damping property, element is placed on vibration damping equipment inside and is parallel to each other or vertical arrangement, in the hope of neat, attractive in appearance; Do not allow the irregular dislocation of element overlapping generally speaking, accomplish that element arrangements is compact.
