Wire rope shock absorber
is a kind of shock absorber, which is widely used in machinery, automobiles, railway locomotives, water transport vehicles, aircraft and other aircraft. It can be said that equipment cushion should be used wherever shock absorption and isolation are needed. Installation of shock absorber - wire rope isolator under equipment is the most widely used effective measure to control vibration in engineering at present. After installing this kind of shock absorber, it can really reduce the transmission of vibration and impact force. As long as the shock absorber is properly selected, the effect of shock absorption can be more than 85%-90%, and large foundation can be avoided. For general small and medium-sized equipment, it can even be done without foot screw and foundation, as long as the ordinary floor can bear the static load of the equipment.
Principle of Product Structure
The wire rope vibration isolator is made by winding the wire rope into a spiral shape and fixing it between two metal plates arranged along the nut. Its stiffness and damping depend on the diameter, number of strands, number of circles and winding mode and size of the wire rope. It is a new type of vibration isolator with non-linear characteristics and dry friction damping. The wire rope winded in a certain direction is used as elasticity. Components have obvious hysteresis characteristics, and their energy dissipation comes from friction, extrusion and slip between steel wires. When the amplitude of excitation and impact is large enough, internal friction occurs between the strands of the isolator wire rope, which is contrary to the direction of wire rope movement, thus consuming a large amount of energy, attenuating vibration and impact strength; when the amplitude of vibration is small, the strands of the wire rope are twisted together due to friction and do not produce relative slip, thus showing good linear elasticity and maintaining the stability of the system, so the wire rope is separated. The vibrator is adapted to the complex and changeable working conditions of vibration and impact, and its adaptive ability is particularly strong. It can effectively avoid strong resonance and impact, thus playing the role of cushioning and isolating vibration.
