At present on automobile vibration parts, normally used a kind of dynamic vibration absorber is as shown in Figure 3, its structure comprises support 1 ＇, rubber elastomer 2 ＇ and mass block 3 ＇, typically use rubber elastomer as elastic element, determined the stiffness K value of dynamic vibration absorber by the performance such as size, Static stiffness of rubber parts; Using slug etc. as the mass block of dynamic vibration absorber, the quality of slug is exactly the quality m of dynamic vibration absorber
2.Metallic gauge block and rubber elastomer, mounting bracket closely bond together by the one-body molded rear three of mould on the equipment such as vulcanizer, become K value and the fixing dynamic vibration absorber of m value, have fixing frequencies omega
a.For undamped dynamic vibration absorber mainly according to given frequencies omega
adesign, but as ω and ω
adeparting from slightly large rear dynamic vibration absorber acts on not quite substantially, and therefore only can play absorbing effect under specific frequency, the using scope of undamped dynamic vibration absorber is restricted.
In the practical engineering application such as automobile new car model development design, current development process is generally pass through simulation model, calculate and the parameter such as absorber mass, rigidity of optimization the best, then make bump leveller exemplar by bump leveller manufacturer and be arranged on real vehicle and test.Because the result of real steering vectors result and simulation calculation has certain difference, need according to real vehicle using effect again motivation of adjustment bump leveller parameter and again made to be installed on real vehicle after exemplar by bump leveller manufacturer and carry out testing authentication.Because the Mould Machining of bump leveller is complicated, the cost high process-cycle is simultaneously longer, and the cycle that designs and produces generally needs 2 ~ 4 weeks, has therefore had a strong impact on the development progress of vehicle complete vehicle and has caused development cost high.
[summary of the invention]
Therefore, the object of the invention is for prior art not enough, provide a kind of can the dynamic vibration absorber of quick adjustment resonant frequency and oscillating mass, it is by realizing quick adjustment bump leveller parameter, thus adapt to different vibration damping demands, increase work efficiency, save production cost.
For achieving the above object, the present invention by the following technical solutions:
A kind of can the dynamic vibration absorber of quick adjustment resonant frequency, it is characterized in that including mass block, mounting bracket, rubber elastomer, described mass block is provided with mounting hole, described mounting bracket includes fixed panel and connecting rod, one end of connecting rod is fixed on fixed panel, the other end is fixed with rubber elastomer, and described connecting rod is fixed in the insertion mounting hole of the movable adjustment in one end of rubber elastomer.
As above can the dynamic vibration absorber of quick adjustment resonant frequency, it is characterized in that by mobile or rotate and quick adjustment actual play elastic component effect rubber elastomer size thus fast and adjust the K value of bump leveller subtly.
As above can the dynamic vibration absorber of quick adjustment resonant frequency, it is characterized in that rubber elastomer screw thread is fixed on connecting rod.
As above can the dynamic vibration absorber of quick adjustment resonant frequency, it is characterized in that being provided with internal thread in mounting hole, described rubber elastomer is provided with outside thread and is connected with mounting hole spiral.
As above can the dynamic vibration absorber of quick adjustment resonant frequency, it is characterized in that described mass block is cylindrical.
