Application of Wire Rope Vibration and Isolator in Tracked Vehicle Equipment

Tracked armored vehicles are the most important conventional weapons in modern warfare. All countries in the world, especially the western military developed countries, have developed and produced a variety of amazing armored vehicles, such as main battle tanks, infantry fighting vehicles, self-propelled artillery, missile launch vehicles, etc. But for a long time, the vibration of vehicles has been a problem that has plagued the vehicle engineering community.

The gas pressure in the engine cylinder, the reciprocating inertial force generated by the moving parts and the unbalanced inertial force will cause the whole engine to generate severe vibration, which will be transmitted to the carrier through the engine's suspension system, causing the carrier and parts to vibrate. It will cause fatigue and damage to vehicle structure and mechanical equipment components, affect the normal use of machines and equipment on the vehicle, and increase maintenance costs. For military armored vehicles, it also affects the durability and comfort of the vehicle and the firing accuracy of the firepower system. This means that the combat system can not function properly and reduce its concealment; it also affects the efficiency and physical health of the insiders and reduces their combat capability.

A tracked vehicle is a special type of off-highway vehicle. Its field mission transportation environment is a kind of broadband vibration, which is caused by the combination of the support, structure and pavement flatness of the vehicle body. The typical distance is 500KM, the road conditions are poor, and the road surface and original terrain will be experienced in the battle environment. The harsh working environment of the tracked vehicle equipment puts strict requirements on the selection of the vibration isolator. The general vibration isolator is incapable, and the wire rope vibration isolator can effectively suppress the resonance. When the external excitation frequency is close to the natural frequency of the isolator, when the amplitude is amplified, the frequency conversion characteristic of the wire rope vibration dampers automatically changes the natural frequency to avoid resonance.

The wire rope vibration isolator is composed of two upper and lower metal plates and a plurality of tightly wound steel wire ropes. It utilizes the dry friction between the strands of the steel wire to absorb and dissipate the vibration energy to achieve the vibration damping effect. The coil spring-shaped steel wire rope is tightened and shaped by the upper and lower clamping plates to withstand the force in any direction. It has three-way protection for the equipment, and can withstand the forces of compression, stretching, shearing or rocking even in the cantilever installation state. Wire rope vibration dampers can generate a large dynamic displacement, so it can attenuate strong impact. Due to the damping characteristics of the wire rope, a large number of low frequency and high frequency vibrations can be absorbed and dissipated, and its damping characteristics are related to the strain applied to it. It has a large damping for large amplitude motion, moderate damping for small amplitudes, and a bending hysteresis characteristic when passing through resonance. Due to the use of all metal materials, it is not affected by ambient temperature, ozone, grease, sand, salt spray and organic solvents. It has a very long storage period and service life, which is the best choice under harsh conditions.
