Vibration Plate FAQ

Linear Vibration vs Pivotal Oscillation

Linear vibration and pivotal oscillation are very different types of movement patterns. Pivotal oscillation is created using a planar four-bar linkage device. Linear vibration is create using a spring and eccentric wheel system. The name linear vibration comes from a physics attribute of the spring: the compression or extension force of a spring is in linear relationship with the length of spring displacement.

 

Noise of VT003F

Vibration plates produce mechanical noises and sound wave noises. Mechanical noises are produced due to the friction and impact between moving parts, like bearings, springs and all other assemblies. The higher the frequency the more noise of both type created.

Sound wave becomes audible to human when the frequency is above 20Hz. It is inevitable for a vibration machine that runs above 20Hz. Mechanical noise can be reduced through increasing parts precision and assembly quality.

Mechanical noise has been a challenge for the manufacturing of high frequency vibration plate like VT003F. It is also an important quality level indicator for a vibration machine. Through years of continuous improvement, we are able to reduce the mechanical noise of VT003F to a reasonable level. At below 30Hz, VT003F runs relatively quiet and allows users to listen to radio or watch TV while using the vibration. Above 30Hz, the noise level increases quickly. We conducted noise measurement test and compared the results with the noise range of other typical noise sources. Below link leads to our noise measurement report.

EMF Produced by VT003F

Like all other household electric appliances, vibration plate produces electric and magnetic fields (EMF). According to EPA, there is no clear scientific evidence that EMF affects health. EPA does not define a safe or hazardous level of EMF exposure. However, many people report headache, anxiety, depression, nausea, and sleep disturbances when exposed to EMF at certain strength. Some customers expressed concerns about the EMF produced by VT003F. Therefore, we measured the EMF strength on VT003F. The maximum magnetic field strength measured at one foot above the foot plate is 1.3 milligauss at the highest intensity setting. Our EMF measurement are performed in house, not certified or confirmed by any lab. We compared the our measurement results with the EMF data of other household electric appliances and the data from EPA report. Below link leads to our EMF measurement report.

VT003F Compared with Power Plate

Power Plate offers a series of high-end vibration plates, all are linear vibration type, the same mechanizs as VT003F. Many VT003F users reported similar experience between using VT003F and using Power Plate. Power Plate developed a robust consumer grade vibration plate named Personal Power Plate. Its parameter and performance is comparable to those of VT003F. The side by side comparison of the two models will help understand the pros and cons of each model.

Understanding Vibration G-force

G-force is an important parameter that indicates the intensity of vibration. It is actually not a force but an acceleration rate expressed using gravity acceleration G.

How to calculated G-force?

 

Impact of G-force on Human Body

Vibration plate can put high G-force on the user. It is like to put multiplied gravity on the user. Vibration G-force only last a tiny fraction of a second in a vibration circle, so the impact on the user is minimal. The short pulse of the multiplied gravity force creates unique stimulation on muscles, tendons, ligaments and bones.
