Vibration and Dynamics were among the disciplines on which the company was founded. We are proud to continue offering the highest levels of service and quality in both these areas.
Vibration and Dynamics are subsets of the broader field of acoustics, is a branch of physics involving the study of sound - mechanical waves in gases, liquids, and solids.
The sources of sound and vibration include rail transport, road traffic, excavation and construction equipment, mining blasting and explosives, wind and earthquakes. In general, we study the motions and dynamic forces on humans, building structures, and machinery. By quantifying the motion (e.g. in terms of frequency and amplitude), we can assess the potential impact of vibration on human comfort and the likelihood of damage to structures and machines. Vibration analysis can also be used as a diagnostic tool to identify and replace malfunctioning components of machinery or to isolate and rectify the source of excessive noise emissions.
The study of acoustics and vibration directly influences land use planning, building location and design, transportation systems, mine and quarry operations, industrial processes and major infrastructure construction methods. Heggies has extensive experience in all of these areas.
We have also conducted numerous specialised mechanical vibration analysis projects, including fatigue and failure investigation, hand-arm vibration and whole body vibration (ride quality) as well a wide range of projects involving road, rail and aircraft transport, shipping, and wind engineering. Our skills in finite element modelling, experimental modal analysis and multi-channel vibration monitoring allow us to provide the full range of services to our clients.
Heggies experience has a long history of involvement in mine and quarry noise, industrial noise and demolition and construction noise projects. This strong technical background is supported by our excellent reputation in presenting information during the planning and approvals process, as well as for community consultation and expert witness tasks.
