1. Improve the balance precision of the moving parts of the rotating assembly line and reduce the contact surface of the solid parts of the assembly line with the periodic excitation force of the moving parts of the rotating assembly line.

2. Increase the characteristic impedance of different elastic materials to reduce the vibration of solid sound. Install shock absorbers on large parts to isolate vibration.

3. The assembly line that reduces noise transmission adopts materials with high internal loss coefficient to make noisy parts of mechanical equipment, or increase resistance on the surface of vibrating parts of the assembly line to reduce sound radiation efficiency.

4. Improve the processing accuracy and smoothness of the moving components in the assembly line, select the appropriate work difference match, and control the clearance between the moving components.

5. Reduce the vibration amplitude of the moving components of the assembly line, and use sufficient lubrication of the assembly line to reduce the friction and avoid the impact and impact of the moving components.

6. The impact force and velocity between the impact components of the pipeline are reduced, and the impact time between the impact components of the pipeline is prolonged.
