Composite shock absorbers, Huaneng pipeline equipment diagram, the damping spring shock absorbers

Spring-damper is a common mechanical parts. Almost all industrial products, such as aircraft, trains, automobiles and other vehicles, electrical equipment, instruments, power machinery, tools, machinery, agricultural machinery, even small clocks, door locks or automatic umbrella, such as everyday household items are also inseparable spring shock absorbers. Spring shock absorber shape is simple, but it plays a very important role in the machine, if a spring-damper damage, as well as a part of the whole machinery of machinery and equipment will fail or stop running, so more and more It attracted people's attention, the current world for spring-damper design, material selection, manufacturing, heat treatment and testing have been strict standards and guidelines. Spring-damper effect, the total use relies on point when talk is elastic and spring structure of the material, it is generated or deformation recovery, able to work or kinetic energy into mechanical deformation energy, or the deformation energy into mechanical work or kinetic energy. Because of this feature, the spring shock absorber damping of mechanical products that can be used or buffer, controlling the movement and storage of energy, force and torque measurements, and as mechanical power. Broadly speaking, those who use flexible parts, such as the elastic elements of the various different purposes, are outside the scope of bomb-making. The vibration and noise of mechanical or plumbing in the work produced is a wave phenomenon. Fluctuations and mechanical vibration pipeline is closely related form of exercise, vibration is the source of fluctuations, the control elastic medium is the key to control the vibration in the morning, spring-damper is effectively comply with vibration, wave to mechanical piping and other equipment, thereby effective control of noise. When the effective control of the first to use mechanical vibration damping spring device control objects made through the equilibrium position reciprocating periodic movement, etc. (such as hand on the drumhead can control the vibration when the drumhead drumming his fingers on the vocal cords can control talk vocal cord vibration, etc.). Damping device is the use of the basic form of the motion of matter, it is an effective machinery and equipment production processing equipment vibration. Machinery, pipe vibration stabilized is made free vibration damper spring. On one level, smooth desktop, place a spring vibration system, one end of the spring is fixed and the other end attached to a mass m of the object, the object is called a transducer. Spring-mass-spring-damper assumed excluding the transducer can only do linear motion along the axis of the spring on the desktop level, without regard to friction and other resistance transducer and mechanical equipment or piping equipment. When the oscillator is no pulling or pushing force in a relatively static state, then the location of the transducer called central position or balanced position to represent. When the vibrator is subjected to a force along the axial direction of the spring, as the tension, the spring will be stretched, resulting in a point on the oscillator equilibrium position of bombs J wins reply force. In the spring of bomb J wins limit, the greater the deformation of the spring, the elastic restoring force increases. According to Hooke's law, elastic restoring force F of the spring stiffnesses. After the removal of the external force, oscillator will be under the elastic restoring force to balance position as the center reciprocate, this is a shock absorber works. Because already set without regard to friction and resistance, vibration damper spring will continue to go on, this is the free spring oscillator stability control process noise.
