What is the selection method for damping spring vibration isolator?

1、 Determine vibration isolation requirements

 

1. Clearly identify the type, weight, and operational characteristics of the equipment that requires vibration isolation.

 

2. Analyze the vibration frequency and amplitude generated by the equipment to determine the required damping effect.

 

2、 Calculate the total operating weight of the computing device

 

The total operating weight of the equipment includes the static weight and counterweight of the equipment, multiplied by a safety factor (usually 1.3) to obtain the operating weight.

 

3、 Select vibration isolators based on equipment size and layout

 

The layout of vibration isolators should consider the shape of the equipment base and the distribution of forces.

 

The spacing between vibration isolators is generally not more than 2 meters to ensure uniform distribution and provide good vibration isolation effect.

 

4、 Select the appropriate vibration isolator model

 

1. Choose the appropriate vibration isolator model based on the load that each vibration isolator needs to bear (the total operating weight of the equipment divided by the number of vibration isolators).

 

The optimal load of the selected spring vibration isolator should be slightly greater than the actual load to reduce vibration isolator fatigue.

 

5、 Verify the performance of vibration isolators

 

1. Verify the horizontal and vertical stiffness of the spring, ensuring that the ratio of horizontal stiffness to vertical stiffness is greater than or equal to 1, to ensure the stability of the vibration isolator.

 

2. Ensure that the natural frequency of the spring damper is sufficiently different from the operating frequency of the equipment (frequency value should be greater than 3) to achieve efficient vibration isolation.

 

6、 Consider the durability and corrosion resistance of vibration isolators

 

1. Choose vibration isolators that have undergone good surface treatment, such as baking paint treatment, galvanizing treatment, or zinc aluminum treatment, to prevent rust and extend their service life.

 

7、 Installation and Debugging

 

During the installation process, ensure that the vibration isolator is correctly placed and securely connected to the equipment.

 

2. After the equipment is running, necessary debugging and performance testing should be carried out to ensure that the vibration isolator achieves the expected effect.

 

In summary, the selection method of damping spring vibration isolators requires comprehensive consideration of equipment characteristics, weight, size, vibration frequency, and performance parameters of the vibration isolators. By precise calculation and reasonable selection, the vibration isolator can ensure optimal performance in practical applications, improving the stability and service life of the equipment.
