阻尼彈簧減震器有什麼作用What is the function of damping spring shock absorber

    阻尼彈簧減震器是一種對位移反應靈敏的振動控製裝置；彈簧減振器主要適用於核電廠、火電廠、化工廠、鋼鐵廠等的管道及設備的抗振動。常用於控製掛續性的流體振動激擾（如流體脈動、兩相流、高速流和風振等）的管系振動。彈簧減振器能有效地控製各種頻率的振動和擺動，但在一定的程度上限製了管道的正常熱位移。設計時應充分考慮彈簧減振器對管道產生的附加力。

Damping spring shock absorber is a kind of vibration control device which is sensitive to displACEment; it is mainly used for anti vibration of pipes and equipment in nuclear power plant, thermal power plant, chemical plant, steel plant, etc. It is often used to control the pipe system vibration caused by continuous fluid vibration, such as fluid pulsation, two-phase flow, high-speed flow and wind vibration. The spring damper can effectively control the vibration and swing of various fREquencies, but to a certain extent, it limits the normal thermal displacement of the pipeline. The additional force of the spring damper on the pipeline should be fully considered in the design.

    為了減少路面對車輛的振動和衝擊，需要彈簧把這些吸收振動和衝擊的能量，彈簧在懸架中就是一個儲能元件，但是暫時儲存起來還不行，還要把這些對車輛乘坐舒適性和操縱穩定性不利的能量消耗掉，這是就輪到減振器登場了。液壓式減振器的工作原理是當車架與車橋作往複相對運動，而活塞在缸筒內往複運動時，減震器殼中的機油通過一些狹窄的孔反複地從一個腔體流到另一個腔體。此時，孔壁與油的摩擦和液體分子的內摩擦對振動形成阻尼力，將機體和框架的振動能量轉化為熱能，被油和減震器殼吸收，然後消散，到大氣中去。簡而言之，動能轉化為熱能。如果減震器在試驗台上連續運行幾分鍾，減震器氣缸的外壁將變得非常熱，甚至很熱。減震器的性能應通過減振試驗來評價。

In order to reduce the vibration and impact of the vehicle on the road, springs are needed to absorb the vibration and impact energy. The spring is an energy storage element in the suspension, but it is not enough to store it temporarily. It is also necessary to consume the energy that is unfavorable to the riding comfort and handling stability of the vehicle. It is the turn of the shock absorber. The working principle of the hydraulic shock absorber is that when the frame and the axle make recIPRocating relative motion, while the piston reciprocates in the cylinder barrel, the oil in the shock absorber housing repeatedly flows from one cavity to another through some narrow holes. At this time, the friction between the hole wall and the oil and the internal friction of the liquid molecules form a damping force on the vibration, which converts the vibration energy of the body and the frame into heat energy, which is absorbed by the oil and the shock absorber shell, and then dissipated to the atmosphere. In short, kinetic energy is converted into heat. If the shock absorber runs continuously on the test bench for several minutes, the outer wall of the shock absorber cylinder will become very hot, even very hot. The performance of shock absorber should be evaluated by vibration reduction test.

    減振試驗一般隻在新設計的減震器試生產時進行，但批量生產後，無需逐個進行減震器試驗，隻需進行定型試驗。但對於特別重要的減震器，或在減震試驗中必須調整以滿足技術要求的阻尼彈簧減震器，應逐個進行試驗。整機應進行減震試驗，試驗條件為實際工作條件。

Generally, the vibration reduction test is only carried out during the trial production of the newly designed shock absorber, but after the mass production, it is not necessary to carry out the shock absorber test one by one, only the type test is needed. But for the special important shock absorber or the damping spring shock absorber which must be adjusted to meet the technical requirements in the shock absorption test, the test should be carried out one by one. The shock absorption test should be carried out for the whole machine, and the test conditions are the actual working conditions.
