Selection method of vibration damping pad:
2. The area of vibration damping pad is decided according to the weight and working situation of equipment, it is cut based on a standard cushion block.
Area of vibration damping pad =Equipment weight /The bearing capacity of the selected vibration damping pad
For the equipment with shock and weight increase, the coefficient of overweight should be considered when choosing.
Bearing area = 3500 kg×1.3/7 kg/cm² = 650 cm²
Area of a single support = 650 cm²/6 ≈110 cm²
The vibration damping pad under the support must be exposed by 1cm margin, so the cushion block should be cut into 12×12 cm².
