Effective vibration suppression for home appliances
Refrigerators, air conditioners, and washing machines all contain compressors that generate significant vibration during operation. To maintain performance and protect both the production and the surrounding environment, high-quality vibration dampers are essential. These appliances also endure intense vibrations during transport, requiring components with exceptional durability. With decades of vibration-resistant research and advanced simulation analysis, Yamauchi designs optimal vibration-resistant rubber components using a wide array of materials. Our parts are manufactured under strict quality control, from production to final inspection, to ensure reliable, high quality performance every step of the way.
What Makes Our High-Performance Vibration Dampers Unique?
Precision Hardness Tuning in 5-Degree Increments
Controlling the hardness of rubber is the key to effective vibration suppression in dampers and insulators. At Yamauchi, we fine-tune hardness in 5 degree increments between the A3 to A60 range. This intricate control allows Yamauchi to adjust the resonance point even after the component shape and mold are finalized, enabling flexible tuning to achieve optimal performance to meet your needs.
Wide-Range Vibration Control with Advanced Material Grading
Inverter-controlled compressors generate vibrations across a broad frequency spectrum due to their variable speeds. To meet the need for comprehensive vibration suppression, Yamauchi offers materials graded across a wide dynamic viscoelasticity (tan δ) range of 0.1 to 0.8. This will effectively minimize vibration amplification across all frequencies.
Our thermoset rubber provides excellent compression strain resistance for high reliability, superior weather resistance with no ozone cracking (tested at 40°C/50 pphm for 72 hours), and supports complex geometries. All materials are RoHS Directive compliant, making them both high-performance and environmentally friendly.
The Unique Technology Behind Our Rubber: Our Two Methods of Vibration Isolation
Shifting the Resonance Point
Resonance at specific frequency ranges can be effectively avoided by adjusting the hardness of rubber. As showcased in Figure 1, this graph highlights that lowering the hardness of rubber shifts the resonance point downward. Yamauchi applies advanced expertise and fine-tuned hardness control in 5 degree increments across a wide A3 to A60 range, enabling flexible, precision tuning to match your performance needs.
The Reduction in Vibration Transmission
Resonance can be suppressed by changing the rubber’s dynamic viscoelasticity. Figure 2 showcases that using a rubber compound with a higher tan δ (greater energy loss and lower elasticity), helps lower resonance magnification. Yamauchi can meet your diverse needs by offering materials graded across a wide tan δ range from 0.1 to 0.8.
