氣桿阻尼器疲勞試驗機 氣彈簧疲勞試驗機 

一、概述：

氣彈簧是以氣體和液體為工作介質的一種彈性元件，由壓力管，活塞，活塞桿及若干聯接 件組成,其內部充有高壓氮氣，由于在活塞內部設有通孔，活塞兩端氣體壓力相等，而活塞兩側的截面積不同，一端接有活塞桿而另一端沒有，在氣體壓力作用下， 產生向截面積小的一側的壓力，即氣彈簧的彈力，彈力的大小可以通過設置不同的氮氣壓力或者不同直徑的活塞桿而設定。與機械彈簧不同的是，氣彈簧具有近乎線 性的彈性曲線。標準氣彈簧的彈性系數X介于1.2和1.4之間，其他參數可根據要求及工況靈活定義。

First, an overview:

Gas spring is to gas and liquid as working medium, an elastic element, by the pressure tube, piston, piston rod and a plurality of connecting pieces of the composition, the internal charge with high pressure nitrogen, as in the interior of the piston is provided with a through hole and equal in at both ends of the piston gas pressure, and cross section of the piston on both sides of the product different, one end is connected with the piston rod and the other end is not, in under the action of gas pressure to produce to the cross-sectional area of the small side of the pressure, the gas spring elastic, elastic force can by setting different nitrogen pressure or different diameter piston rod set. Unlike the mechanical spring, air spring has a nearly linear elastic curve. The elastic coefficient of X between 1.2 and 1.4 of the standard gas spring, other parameters according to the requirements and conditions of flexible definition.

二、特點：

1.能實現2種功能:座面反復沖擊、座面一次性沖擊; 2.采用鋁型材框架結構,不銹鋼測試平臺,結構美觀大方; 3.利用電磁鐵吸合和釋放,完全模擬自由跌落狀態,跌落過程無阻力,噪音低; 4.椅子水平方向采用“腳杯”結構保持位置,使椅子在垂直方向不受外力約束; 5.操作簡易,無需任何專用工具輔助;具有停電斷電記憶功能; 6.可選不同控制形式。
