英文What is the selection method for using damping spring vibration isolators on equipment?
2025-12-04
1、 Determine the total operating weight of the equipment
Firstly, it is necessary to calculate the total operating weight of the device, which includes its static weight and dynamic load during operation. For safety reasons, this total weight is usually multiplied by a safety factor.
2、 Select vibration isolators based on equipment size
- The maximum distance between vibration isolators should not exceed 2 meters to ensure the shock absorption effect.
-
If the shape of the equipment base is irregular, vibration isolators should be arranged reasonably according to the weight and force distribution of the equipment.
3、 Calculate and select the appropriate vibration isolator model
- Based on the total operating weight of the equipment and the number of vibration isolators, the load that each vibration isolator needs to bear can be calculated.
- Choose a model that is close to the optimal load of the spring vibration isolator. Generally, the optimal load of the selected spring vibration isolator should be slightly greater than the actual calculated load.
4、 Consider the stiffness and damping of the spring
- The horizontal and vertical stiffness of the spring should meet certain proportional requirements, such as the ratio of horizontal stiffness to vertical stiffness should be greater than or equal to 1 to ensure the stability of the vibration isolator.
- Choose appropriate damping to effectively reduce vibration and impact during equipment operation.
5、 Check the surface treatment of the spring vibration isolator
- The surface treatment of spring vibration isolators should be done through baking paint treatment, galvanizing treatment, or zinc aluminum treatment to prevent rusting in a short period of time and extend the service life of the vibration isolator.
6、 Consider the relationship between the operating frequency of the equipment and the natural frequency of the vibration isolator
- To ensure vibration isolation efficiency, there should be a certain difference between the operating frequency of the equipment and the natural frequency of the spring damper, and it is usually recommended that this difference value be greater than 3.
In summary, selecting a suitable damping spring vibration isolator requires comprehensive consideration of multiple factors such as equipment weight, size, operating frequency, as well as spring stiffness and damping. Through scientific calculations and reasonable selection, vibration isolators can ensure optimal performance in practical applications.
