Shock absorber, also known as shock absorption. The shock absorber of common including hydraulic shock absorber and mechanical shock absorber. Hydraulic shock absorber is divided into hydraulic shock absorber and two-way shock absorbers.Hydraulic shock absorber using liquid compressibility and liquid during the compression characteristics of energy absorption and dissipation energy flows, achieve the purpose of reduce or eliminate vibration.Two-way shock absorber in addition to the axial compression, you can also reverse impact into the axial impact, by using the principle of hydraulic shock absorption to reduce or eliminate the longitudinal vibration and torsional impact.Mechanical shock absorber has a good damping effect, long working life, high ratio of performance to price.Vibration generation: vibration is attached to the product in the process of impact. Hit the ball, the ball, and shoot with great momentum, released during the impact. Part of the energy used to change the direction of motion; As a necessary part of energy loss is released, the vibration and sound.Vibration eliminating: vibration is a kind of energy, energy cannot disappear, but can be transmuted and transmission. In order to eliminate the effect of vibration, the best thing to do is add buffer in the process of vibration transfer device. Buffer device, usually has a very good deformation ability, after vibration transfer to buffer device can cause deformation and more low frequency vibration, eventually translate into heat energy, thus achieve the goal of transformation and cut. Elastic is good "shock absorber material", but does not mean that it is a good suspension device, the stand or fall of suspension effect should be depending on the specific material and design, the racket shock design diversity, the principle is not the same. Have a plenty of direct absorption of vibration, the greater the weight, the better (than surface), have a plenty of local cable vibration decomposition to adjacent cables (contact line the more the better) shock generally installed in the racquet face near the handle side. According to the data provided by the manufacturer, shock absorbers can reduce a lot of vibration. But actually it just reduces the shock of strings and make the drive more in a low voice. Generally not recommended for beginners to use it, because it will affect the establishment of the ball.
