Boyd Vibration Dampners

Description
Many products will produce unwanted noise and vibration under normal operating conditions. This excessive noise and vibration, also known as NVH, is often interpreted as poor quality and can negatively impact consumer perception. It also negatively affects desired performance of the device through accelerated wear and tear, decreased efficiency, or in extreme cases, shortened product life through mechanical failure. Control of these noise, vibration, and harshness (NVH) issues often fall to a variety of add-on treatments applied to a product’s structure with the goal to: absorb or block the transmission of noise, isolate the transmission of vibration between components and damp excessive vibration by reducing the structure’s resonant behavior through solutions like sound absorption, vibration damping and shock absorption. Boyd offers a wide array of custom converted solutions utilizing highly engineered materials that are tailored to the specific application. The treatment design and material selection is made with a detailed understanding of the structure itself, the governing dynamics driving the NVH issue, and the environmental requirements to be met. Vibration damping can be added to a structure in many ways and is predominately used to reduce excessive resonant behavior. The most common type is material-based damping created by straining visco-elastic materials (VEM) in either shear or tension/compression. Performance is optimized by selecting a VEM with maximum loss factor in the temperature and frequency range of interest, and with a stiffness range that maximizes strain energy in the damping element. A constrained layer damper (CLD) combines a rigid constraining layer with a thin damping layer to create cyclic shear stresses in the VEM. An unconstrained layer damper is placed between two components moving relative to each other so cyclic stresses are imparted on the damping pad or link that connects the components in tension/compression. Vibration damping requires optimization through material selection, treatment design and placement to ensure good performance.
