橡膠減震器的性能介紹

   橡膠減震器具有一定的阻尼,在共振頻率附近有較好的減振效果,并符合運用于垂直、水平、旋轉方向的隔振,勁度具有較寬的范圍可供挑選。與鋼彈簧相比,其欠缺是隔振性能易受溫度影響,在低溫下運用,性能非常不好。靜態(tài)壓縮量低且本來就有頻率高于5Hz,由于這個這種減振器對具有較低的干擾頻率(本來就有頻率低于5Hz)并且重量 、別大的設備不舒服合運用。這類產(chǎn)品,由于安裝方便,效果清楚顯露,在工業(yè)和人群眾的生活活所運用的建筑的設備減振工程中得到了廣泛的應用。預設和選用橡膠減震器的關鍵是準確估算其勁度和本來就有頻率,以使承擔負荷在其準許范圍內(nèi)。這個之外還應注意,靜負荷時的 、大壓縮量不應超過原長度的10%-15%,以擔保一定運用保存生命的年數(shù)。
   
The rubber shock absorber has a certain damping, has a good effect in the vicinity of the resonance frequency, and conforms to the vertical, horizontal, rotary direction of vibration isolation, stiffness has a wide range for selection.Compared with the steel spring, its lack of vibration isolation performance is easy to be affected by temperature, in low temperature, the performance is very bad.Static compression is low and has a frequency higher than 5Hz, due to this shock absorber has a low interference frequency (already has a frequency lower than 5Hz) and the weight of the equipment is not comfortable with the use of large.This kind of products, due to the convenient installation, the effect is clear, in the industrial and people's life by the use of the building equipment vibration engineering has been widely used.The key to presetting and selecting a rubber shock absorber is to accurately estimate its stiffness and inherent frequency so that the load is within its permissible range.In addition to this should also be noted, static load, large compression should not exceed the original length of 10%-15%, in order to guarantee a certain use of life saving years.
