Embodiment
For example the utility model is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～3, the utility model comprises: fixed base 1, adjustable support rod 2, top cover 3, whorl brace rod 4, space bar 5, upper compressing tablet 6, location piece 7, portable connecting groove 8, locating pin 9, fixed connection place 10, metal-rubber element 11.Fixed base 1 plays fixation, in the fixed connection place 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 support rod 2.Adjustable support rod 2 is skeleton parts of this vibration damping equipment, it links to each other with top cover 3 by 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 by portable connecting groove 8 simultaneously.Place metal-rubber element 11 in the casing frame the inside, insert locating pin 9 at fixed base 1 and top cover 3, can the metal-rubber element on top layer be positioned, the metal-rubber element of nexine can be by the extruding location.Since the metal-rubber element can only pressurized can not tension characteristic, the vibration damping equipment that the metal-rubber element forms must make that the up and down tension and compression 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 upper compressing tablet 6, and metal-rubber element 11 forms, and it is as a whole that upper compressing tablet 6 connects into whorl brace rod 4 and space bar 5, and metal-rubber element 11 is spaced apart plate 5 and is divided into two-layer up and down.
Link to each other with this vibration damping equipment when vibration source is threaded connection bar 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 in the situation that satisfy applying working condition can arbitrary arrangement, 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, the utilization ratio of Effective Raise metal-rubber element 11, the utility model proposes a kind of Metal-rubber element arrays arrangement mode---convertible cross arrangement, namely 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, be shaped as the upset signal of rectangular solid metal-rubber element as shown in Figure 2, the specific implementation 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 large in the part space shown in 135 ° of diagonal line hatches part in the accompanying drawing 1.
In conjunction with shown in Figure 1, adjustable support rod 2 is connected on the portable connecting groove 8, lower metal rubber element 11 is placed on the fixed base 1 and arranges, and by locating pin 9 it is fixed, the stressed conversion component of tension and compression that whorl brace rod 4, space bar 5, upper compressing tablet 6 are formed is placed on the central position, framework along adjustable support rod 2 and the stressed conversion component composition of tension and compression is placed arrangement upper strata metal-rubber element 11, add top cover 3 and locating pin 9, positioning metal rubber element 11 positions, by location piece 7, the structure of whole vibration damping equipment is fixed.
In conjunction with shown in Figure 3, during use, adjust quantity and the arrangement of metal-rubber element according to the usage requirement in the operating mode and stressing conditions, at first adjust the size of this vibration damping equipment by portable connecting groove 8, secondly fix the position of metal-rubber element 11 by locating pin 9 and location piece 7, fix at last the position of this vibration damping equipment by the fixed connection place 10 on the fixed base 1, vibration source just can see through the purpose that this device reaches vibration damping.
Metal-rubber is arranged criterion: metal-rubber array effect depends on Series Parallel Elements effect, number of elements and how much spread patterns.
Under normal conditions, all elements should be realized with laying, laying is deferred to principle from bottom to top, for guaranteeing the normal operation of vibration damping equipment, element axisymmetric centered by the straight line of whorl brace rod place distributes, and the selection of element form is according to element arrangements prerequisite compact and that can be full of at last vibration damping equipment inside is screened.
For unidirectional up-down vibration requirement, take space bar as cutting lines, 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 the lateral vibration absorbing effect, and its quantity changes along with the size of lateral vibration absorbing requirement under the prerequisite that satisfies the Central Symmetry principle.
On the value of series parallel connection form and number of elements, the metal-rubber element adopts broad sense Maxwell model and generalized Voigt model, calculate respectively and adopt the needed metal-rubber number of elements of different series parallel connection effects, satisfying geometry spread pattern and the quantity of determining element under the condition of above criterion.
For two kinds and above metal-rubber element, the employing modularization is calculated, determine the vibration-damping function that every kind of metal-rubber element need to be realized, and then determine respectively the number of elements of each module according to model, make array realize substituting the effectiveness in vibration suppression of single metal rubber shock absorber.
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 generally speaking the irregular dislocation of element overlapping, accomplish that element arrangements is compact.
