ANTI-VIBRATION AND SHOCK ABSORPTION DESIGN FOR FACTORIES WITH HEAVY MACHINERY: A TECHNICAL SOLUTION THAT CANNOT BE IGNORED
In industrial factories, especially production facilities with large-volume and high-speed equipment, lines or machines such as hydraulic presses, CNC machines, punching machines, air compressors, crushers, etc., vibration and ground vibration are serious technical problems that need to be addressed from the initial design stage.
Without appropriate anti-vibration and shock-absorbing solutions, mechanical impacts from machinery can seriously affect:
- The operating accuracy of equipment;
- The life of the foundation and factory floor structure;
- The health and safety of workers;
- The stability of adjacent production lines.
The following article shares the principles and solutions for anti-vibration and shock absorption design that Hung Nghiep Phu Construction Investment Co., Ltd. has successfully applied in many large-scale factory projects nationwide.
1. Correct understanding of vibration in industrial workshops
Vibration is the continuous oscillating movement of a structure or foundation caused by the impact from a source such as rotating machinery, stamping, pressing, compressing or by external forces such as forklifts, transporting heavy objects.
In the manufacturing environment:
- Vibration transmitted through the ground can affect other precision equipment in the line.
- Repeated large shocks can cause structural steel fatigue, concrete cracking, and machine foundation deterioration.
- Transmitted vibration can affect adjacent buildings or office areas in the factory.
2. Anti-vibration and shock absorption solutions in factory design
2.1. Separate the machine foundation structure from the main floor
This is a popular and highly effective solution when dealing with heavy machinery that causes large vibrations. Accordingly:
- The machine foundation is designed separately from the main floor system, not directly connected to the concrete floor structure.
- The load and vibration from the machine will only affect the independent foundation block, not spreading to the floor or surrounding structure.
Usually, the machine foundation will be designed deeper and thicker than the floor, and can be combined with an additional rubber layer or anti-vibration layer at the bottom and around the foundation.
2.2. Machine foundation design based on mass principle
Increasing the machine foundation mass is an effective way to reduce the amplitude of vibration. A basic principle in design is: Machine foundation mass ≥ 3 to 5 times the machine mass.
This helps increase stability and reduce vibration caused by the machine. The commonly used material is reinforced concrete, monolithic construction, well compacted and has anchor steel according to the equipment installation drawing.
2.3. Install shock absorbing material
Between the machine foundation and the machine, or between the foundation and the ground, it is possible to arrange layers of shock-absorbing materials such as:
- Technical rubber (rubber pad);
- Vibration isolator;
- Spring isolator;
- Pneumatic isolator (used in ultra-precision equipment).
The use of shock-absorbing materials must be based on the type of machine, vibration frequency, load and operating frequency.
2.4. Reasonable layout of production space
If there are many large vibration-causing devices in the same workshop, it is necessary to arrange them reasonably:
- Do not place stamping machines or compressors near assembly, inspection or office areas;
- Arrange soundproof and vibration-proof partitions, use masonry walls or soundproof panels;
- Prepare technical distances between high vibration areas and sensitive areas.
3. Some other technical notes
- Calculate the natural vibration frequency of the foundation to avoid resonance with the operating frequency of the machine.
- The construction of the machine foundation must be absolutely accurate according to the design documents, errors can affect the anti-vibration ability.
- Anti-vibration for pipes, technical systems attached to the machine such as air pipes, water pipes, material pipes... also need to be taken into account.
- Periodically maintain and check the vibration reduction equipment to ensure long-term effectiveness.
4. The role of professional design and construction units
Anti-vibration is not a separate item, but an important part in the design of the structure, foundation and arrangement of factory equipment. Therefore, there needs to be close coordination between:
- Factory design unit;
- Production equipment supplier;
- Machine foundation and floor construction unit.
Hung Nghiep Phu Construction Investment Co., Ltd. with many years of experience in building factories with heavy equipment - from mechanical production, industrial electronics to food processing - always focuses on fully applying anti-vibration and shock absorption solutions right from the design stage, ensuring stable, safe and sustainable operation.
In factories with heavy equipment or precision equipment, uncontrolled vibration is a factor that poses many technical risks and long-term losses. The design and construction of anti-vibration and shock absorption systems not only help protect machinery and construction, but are also a decisive factor in production quality and investment life.
