How Does Vibration Therapy Work? [2022 Update]

Vibration stimulation is unique because it can create rapid repeated mechanical stimulation on human body. We can make a vibration machine with designed frequency and amplitude to achieve our desired pace and magnitude of stimulation. The stimulation comes from the vibration acceleration - G-force.

G-Force and Your Commercial Washer

 · G-Force is a relative measurement generally used to compare commercial washer extraction capabilities (spin speeds). Higher G-Forces lead to less water being left in the goods after the wash program is complete, meaning shorter drying times or faster ironing, and reduced energy consumption to dry or finish the goods.

Vibrations on CNC machines

 · Vibrations on CNC machines. Vibration problems during machining process generally result in noise, bad surface quality and sometimes tool breakage. The column talks on what causes these vibrations, and how they affect the part. Machining vibrations, also called chatter, correspond to the relative movement between the workpiece and the cutting tool.

Rotating unbalance

Rotating unbalance is the uneven distribution of mass around an axis of rotation. A rotating mass, or rotor, is said to be out of balance when its center of mass (inertia axis) is out of alignment with the center of rotation (geometric axis). Unbalance causes a moment which gives the rotor a wobbling movement characteristic of vibration of rotating structures.
