Description
Technical field
The utility model is particularly related to a kind of fixable semisinusoidal waveform generator, and it is mainly used in the dynamic environmental test equipment such as shock table, bump testing machine.
Background technology
Impact, bump testing machine is the common equipment of dynamic environmental test, is used for analog equipment at the suffered single of transportation or use or the shock environment of repetition, with the reliability of examining its function under this environment and the integrity of structure.Semisinusoidal waveform generator is placed between two impacting bodies, utilize its elastic deformation to produce corresponding half-sine shock pulse, reach simulation and reproduce the shock environment that product stood.Common semisinusoidal waveform generator is the superpolymer cushion pad 2 ' of a vertex of a cone cylindrical shape at present, its upper end band vertex of a cone, and the lower end is smooth, can be placed directly between two impacting bodies, and is as shown in Figure 1, accomplishes the generation of half-sine wave.This semisinusoidal waveform generator architecture is simple, easy to make, but can not be completely fixed on the impacting body; Because himself elastic property, can the spring displacement after being impacted, be inconvenient to impact, the continued operation of impact test; And need operating personnel artificial midway make its playback, have potential safety hazard, for this reason; The technician has adopted on the following impacting body of equipment a locating slot has been set, and shown in Fig. 2-3, cushion pad is placed the improvement project of groove; Spring displacement after controlling it to a certain extent like this and being hit, but under the wide impact of scun, impact test condition, need use the generator that thickness is little, hardness is high; Cross dark locating slot and generator is trapped in the groove can't collide with impacting body, so, the degree of depth of locating slot just is restricted.In addition, under big pulsewidth impact, impact test condition, need use the generator that thickness is big, hardness is low; And for this generator; The more shallow locating slot of the degree of depth can't be well fixing with it, under the effect that receives impulsive force, still can produce the spring displacement; So just need the generator of the more specifications of outfit and the locating slot of Geng Duo specification could satisfy testing requirements, increased the manufacturing cost and the use cost of equipment; In addition, this semisinusoidal waveform generator can't be applied to the horizontal impact test.
The utility model content
The purpose of the utility model is to propose a kind of fixable semisinusoidal waveform generator, and it can be connected with impacting body through elastic buffering pad being fixedly mounted on the holder reliably; And it is simple in structure; With low cost, practical, thus overcome deficiency of the prior art.
For realizing the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of fixable semisinusoidal waveform generator; It is characterized in that: it comprises a holder and an elastic buffering pad; Said elastic buffering pad is close to and is fixed on this holder one end face, open loop-shaped groove on the end face of said holder, and ring groove is by the local complete filling of this elastic buffering pad; Simultaneously, this holder also is fixedly connected with an impacting body.
Preferably, also offer counter sink on the said holder, the part of said elastic buffering pad forms the fastener constructions that cooperates with this counter sink.
Said ring groove has the V-arrangement xsect.
Said elastic buffering pad adopts the superpolymer member, particularly vulcanizable polyamine grease article, and its sulfuration is fixed on holder one end face.
Said holder is fixedly connected through the securing member that is opened in the through hole on the holder and cooperate with this through hole with impacting body.
Said holder can be selected multiple made for use, but preferably adopts hardware.
The utility model is through being fixed on semisinusoidal waveform generator between shock testing machine two impacting bodies; Make shock testing machine in process of the test, after two impacting bodies bumped against, semisinusoidal waveform generator was fixed because of securing member such as screw and holder and impacting body are arranged; The displacement of can not bouncing; Do not need operating personnel to go manually it to be retracted original position, test can be carried out continuously, improved experiment work efficient; Especially utilize its holder that two semisinusoidal waveform generators are separately fixed at up and down on the impacting body, also can obtain the more waveform of broad pulse.
Compared with prior art; The advantage of the utility model is: this semisinusoidal waveform generator architecture is simple; With low cost, can effectively improve experiment work efficient, improve the equipment performance index; Elimination is satisfied the demand of real work because of the potential safety hazard that waveform generator spring displacement brings with minimum cost.
