Hand Arm Vibration (HAV)

Over exposure to HAVs can lead to highly debilitating and painful conditions such as Carpal Tunnel Syndrome and White Finger.  Construction Industries were personnel use power tools and are exposed to hand vibration are of particular risk.  European legislation “The Control of Vibration at Work Regulations 2005” requires employers to monitor and limit their employees’ exposure to vibration.  The engineering team at Xi were responsible for developing the industry leading HAVmeter which automatically monitors and advises users on their vibration exposure.

Sports Equipment

In constant push for performance sports equipment is becoming lighter and faster, unfortunately lighter typically makes an item more prone to vibration.  Xi has assisted in various sporting developments, including:

  • Reactive skis for adapting to snow and ski conditions
  • Force monitoring curling brushes to enhance technique helping the British curling team to Gold in the Olympics

Whole Body Vibration (WBV)

Whole-body vibration (WBV) is transmitted through the seat or feet of employees who drive mobile machines, or other work vehicles, over rough and uneven surfaces as a main part of their job. Large shocks and jolts may cause health risks including back-pain.  Xi can offer advice to employers to ensure they adhere to “The Control of Vibration at Work Regulations 2005”

Advanced Materials and Active Damping Systems

Beyond standards, springs, dampers and elastomers Xi engineers have developed and worked with cutting edge technologies to offer highly advanced vibration solutions.  Including the development of a compact short stroke semi-active damper using Magneto-Rheological Fluid (MRF), also digitised piezo Macro-Fibre-Composite (MFC) piezo patches that develop 3 times the strain of standard piezo patches and originally developed for NASA’s space program. 


Vibration and noise play an important part in all fields of the defence sector from efficiently operating and silent running machinery to protecting the personnel and operators from over exposure to noise and vibration.

Transport Automotive, Rail, Marine and Aerospace

Be it vibration issues with heavy industrial quarry trucks or resonance in lightweight aerospace equipment Xi has experience in diagnosing and resolving problems through rigorous measurement, modelling and solution design.
