Vibration absorbers
Vibration absorbers are mechanical components designed to neutralize dynamic forces, mitigate noise, and protect structural integrity.
They work by either redirecting kinetic energy away from a primary system using a secondary mass, or converting mechanical vibrations into harmless thermal energy via resilient materials like rubber and specialized polymers.
These are physically anchored underneath or around machinery to prevent vibration from bleeding into surrounding building foundations or floorboards.
Anti-Vibration Pads & Mats: Flat, customizable cushions made of composite materials like cork, Styrene Butadiene Rubber (SBR), or Nitrile. They are highly effective for high-frequency attenuation on shop machinery like generators or pumps.
Spring Mounts: Heavy-duty coiled structures optimized for low-frequency vibrations. They offer high static deflection, making them indispensable for large rotating equipment like cooling towers and chillers.
Elastomeric (Rubber) Mounts: Pre-molded rubber blocks bonded to metal fasteners. They decouple structural connections and absorb shocks across medium-frequency spectrums.
Rather than absorbing energy through a soft pad, these systems add a secondary auxiliary mass-spring mechanism directly onto a primary structure.
How They Work: When an external force drives a system close to its natural resonance frequency, the TMD oscillates in destructive interference to cancel out the primary system’s displacement.
Common Applications: Used prominently in long-span footbridges, skyscrapers subject to wind sway, precision industrial CNC cutters, and aircraft frames
Plumbing, HVAC, and refrigeration systems rely heavily on inline dampers to prevent high-pressure lines from cracking under motor stress.
HVAC Braided Absorbers: Metallic, corrugated tubes wrapped in woven wire braiding. They are TIG-welded adjacent to refrigeration compressors to absorb high-frequency pulsations.
Expansion Joints: Elastomeric bellows placed in pipeline paths to accommodate both thermal expansion and fluid-induced pump chatter.
