The vibration problem faced by mining machinery in the working process is a difficult problem that many enterprises have been trying to solve. Engine as the main source of vibration, its vibration propagation has a significant impact on the performance of the machine. This paper discusses the effective way to reduce the vibration of mining machinery.
Vibration source control
Engine vibration source analysis: engine vibration in the work of the engine is mainly caused by the cyclic movement of the centre of gravity of the engine, reciprocating parts of the inertia force, rotating parts of the centrifugal inertia force and gas pressure alternating effects.2.
Selection of vibration isolation device:•
Rubber vibration isolation: the traditional engine uses elastic support to reduce vibration, rubber vibration isolator structure is simple, low cost, reliable performance. According to the force, rubber bearing can be divided into compression type, shear type and compression-shear composite type.•
Spiral wire rope vibration isolation: wire rope vibration isolator has low-frequency large damping, high-frequency low stiffness characteristics, can effectively reduce the vibration of the body, and has the advantages of oil resistance, corrosion resistance.•
Hydraulic vibration isolation: hydraulic support system combines the advantages of rubber support and hydraulic damping, can provide greater damping in the low frequency range, effectively reducing vibration.
Vibration control
Increase system damping: In engineering, when resonance cannot be avoided, the vibration response can be reduced by increasing system damping.
Power Absorbers: Power absorbers are made of viscoelastic damping material with high energy loss. When the vibration is transmitted to the damping material, the vibration energy is consumed through the deformation inside the material to achieve vibration and noise reduction.
Through these methods, the vibration damping performance of mining machinery can be effectively improved to enhance the reliability of the equipment and the comfort of the operator, thereby improving work efficiency and ensuring operational safety.
With the improvement of mining machinery performance requirements, the traditional vibration damping technology has gradually failed to meet the demand, the use of new vibration damping technology has become an inevitable trend.
