Operators, drivers and passengers of machines and vehicles in workplaces can be exposed to harmful levels of whole body vibration. What kinds of tools and equipment can cause ill-health from vibration? Spherical spreading, energy loss and imperfect coupling of the particles, among other factors, cause these seismic waves to dissipate with distance. When we record blast vibration, it is the motion of these particles at a given point that is measured. The main effects of undetected, critical machine vibrations are described below. 2] undesirable noise. Collectively, these effects are known as Hand-Arm Vibration Syndrome (HAVS). they pass and cause them to oscillate. reduce bearing life) and damage equipment. Vibration - Cause and Effect. There are two types of vibration - Whole Body Vibration (WBH) and Hand-Arm Vibration (HAV). EFFECTS OF VIBRATIONS: The effects of Vibrations are: 1] excessive stresses. Vibration can accelerate machine wear, consume excess power, and cause equipment to be taken out of service, resulting in unplanned downtime. Unchecked machine vibration can accelerate rates of wear (i.e. These vibration injuries are divided into three (3) groups depending on the area it affects; it could be neurological, vascular or musculoskeletal. Vibration can cause changes in tendons, muscles, bones and joints, and can affect the nervous system. Other effects of vibration include safety issues and diminished working conditions. Vibrating machinery can create noise, cause safety problems and lead to degradation in plant working conditions.

Whole-body vibration: causes, effects and cures. The effects of vibrations can be considered on the machine tool, work-piece, tool life and the cutting conditions. There are several sources of subsynchronous vibration in IGC’s and most causes will have common vibration signatures specific to it that can be used as a means to identify the root cause or causes.
