How to ensure the service life of rubber shock absorber?
橡膠減震器的有點是具有一定的阻尼，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(zhuǎn)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并且重量 、別大的設(shè)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(shè)備減振工程中得到了廣泛的應(yīng)用。預(yù)設(shè)和選用橡膠減震器的關(guān)鍵是準(zhǔn)確估算其勁度和本來就有頻率，以使承擔(dān)負(fù)荷在其準(zhǔn)許范圍內(nèi)。這個之外還應(yīng)注意，靜負(fù)荷時的 、大壓縮量不應(yīng)超過原長度的10%-15%，以擔(dān)保一定運用保存生命的年數(shù)。
The advantage of rubber shock absorber is that it has a certain damping, and has a good effect of vibration reduction near the resonance frequency, and conforms to the vibration isolation applied in the vertical, horizontal and rotation direction, with a wide range of stiffness to choose from.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 there is already a frequency higher than 5Hz, due to this shock absorber has a low interference frequency and the weight of the equipment, do not feel comfortable with the use.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.
