- Whole-body vibration: An effective workout? - Mayo Clinic
Whole-body vibration can offer some fitness and health benefits, but it's not clear if it's as good for you as regular exercise With whole-body vibration, you stand, sit or lie on a machine with a vibrating platform As the machine vibrates, it transmits energy to your body, forcing your muscles to contract and relax dozens of times each second
- CCOHS: Vibration - Introduction
When a worker operates hand-held equipment such as a chain saw or jackhammer, vibration affects hands and arms Such an exposure is called hand-arm vibration exposure When a worker sits or stands on a vibrating floor or seat, the vibration exposure affects almost the entire body and is called whole-body vibration exposure
- CCOHS: Vibration - Health Effects
Vibration-induced white finger is the most common condition among the operators of hand-held vibrating tools The symptoms of vibration-induced white finger are aggravated when the hands are exposed to cold Vibration can cause changes in tendons, muscles, bones and joints, and can affect the nervous system
- Vibration - Measurement, Control and Standards - Canadian Centre for . . .
Vibration exposure direction is also important and is measured in defined directions Vibration frequencies and duration of exposure are also determined How hard a person grips a tool affects the amount of vibrational energy entering the hands; therefore, hand-grip force is another important factor in the exposure assessment
- Vibration - Introduction Vibration - Canadian Centre for Occupational . . .
The risk of vibration-induced injury depends on the average daily exposure An evaluation of the risk takes into account the intensity and frequency of the vibration, the duration (years) of exposure and the part of the body which receives the vibration energy Hand-arm vibration causes damage to hands and fingers It appears as damage to blood
- vibration 与 ocillation 的区别是什么？ - 知乎
Vibration of a body is the movement of the body about its mean position and can be linear, circular, periodic or non periodic 补充一个，声学上的震动，通常用Oscillation。 展开阅读全文
- CCOHS: Noise - Control Measures
Vibration of large structures (e g , ventilation ducts, guards on machines, equipment supporting structures, etc ) The sound may be amplified by reflective surfaces that are around the devices Aerodynamic sources of noise are air or fluid flows through pipes and fans or as the pressure drops in the air distribution system
- Work-related Musculoskeletal Disorders (WMSDs) - Risk Factors
Whole-body vibration is experienced by truck and bus drivers, for example Localized vibration exposure can be caused by power tools Common symptoms are numbness of the fingers, loss of touch and grip, and pain In addition, the worker may use more force and awkward body positions because vibration hand tools are harder to control
