Vibration Machine VT003F

VT003F's vibration frequency and amplitude are comparable to those heavy duty commercial grade vibration plate. User experiences are similar. VT003F is much light weighted, designed for home use.

The adjustable frequency and two amplitude settings make VT003F a versatile vibration machine for various users. Physically weak people can start with lower intensity settings, gradually adapt to vibration, and progress to higher intensity.

Over 8000 units of VT003F have been sold so far in the US. Its quality, movement patterns, and parameters are well received to be effective in many health improvement applications.

Frequency range for tissue resonance

VT003F's vibration frequency range is designed to match the natural frequency of human soft tissues in order to achieve resonance effect. At resonance, the vibration most effectively induces muscle contraction, creating a high intensive and rapidly repeated mechanical stimulation to our musculoskeletal system and neuromuscular system. Such a unique stimulation may be utilized as a medical intervention for health improvement.

The chart below exhibits vibration frequency ranges of different types of vibration plates, compared to the natural frequency of human body soft tissues.

Structure and Attributes

Structure & Mechanics

VT003F's basic structure is an upper plate and a lower plate connected by four supporting springs. The vibration drive is mounted on the upper plate from below. The control box sits on the lower plate.

VT003F Vibration Machine
VT003F structure illustration

The upper plate and the lower plate are made of ABS material, firmly screwed on two steel frames. The four supporting springs are mounted between the two steel frames. The control panel unit is mounted on the lower plate. The whole structure is very sturdy and light weight.

Motor & Eccentric Wheel Assembly

The vibration drive is an assembly consists of a PMDC motor and 3 pairs of eccentric wheels. The DC motor rotates the eccentric wheels to create centrifugal force that displaces the upper plate in a circling pattern. The movements are regulated by four strong springs that support the upper plate to form the desired vibration.

The vibration frequency can be controlled by adjusting the voltage of the DC motor. The amplitude can be switched between high and low by engaging different numbers of eccentric wheels through motor rotation direction switch.

When switch the amplitude between Hi and Lo while the machining is running on vibration, user can hear a click sound. That is normal.

Floor Vibration & Machine Drifting

Floor Vibration

While VT003F transmits vibration to the user, it also transmits vibration to the floor. Ideally, VT003F should be used on a solid floor that does not vibrate.

If used on a wood frame floor, VT003F will vibrate the floor and the connecting structure. Overtime, the vibration will cause damage to the structure.

In a light-frame wood structure building, VT003F should be used on the ground floor or in the basement.

VT003F should not be used in a mobile home.

Machine Drifting

VT003F is light weighted (26 LB). If there is no body weight on the vibration plate, the vibration generated centrifugal force can overcome the machine weight and cause the machine to drift on the floor.

The 4 suction feet of V003F can effectively hold onto a flat and smooth floor to prevent the machine from drifting.

VT003F does not drift on a carpeted floor because the carpet provides some buffer and friction that prevents the machine from drifting with vibration.

Suggestion & Solution

Use VT003F on a carpeted solid floor.

If needed, place anti-vibration cushion beneath the machine to absorb some vibration.

A set of anti-vibration pads is included in the package of each VT003F machine.

To achieve better result in absorbing vibration transmitted to the floor, a large piece of exercise mat is recommended. anti-vibration cushion

Uneven Vibration Distribution

VT003F's vibration is not evenly distributed on the surface of the upper plate.

  • When the vibration amplitude is set at High, the vibration intensity is off the center line towards the control box direction.
  • When the vibration amplitude is set at Low, the vibration intensity is off the center line away from the control box direction.
  • If the user's body weight is not centered on the vibration center, the springs will produce excessive noise.
un-centered distribution of vibration

The attribute of uneven vibration distribution comes with VT003F's two amplitude setting design. The amplitude change are achieved by changing motor rotation direction to engage different numbers of eccentric wheels.

At forward rotation, the motor engages 3 pairs of eccentric wheels to produce high amplitude. At backward rotation, the motor engages 1 pair of eccentric wheels to produce low amplitude.

The forward rotation push the vibration intensity center forward to the control box. The backward rotation push the vibration intensity center backward, away from the control box. The higher the vibration frequency, the farther the vibration center is a away from the center

User body weight should be put right above the vibration intensity center for a balanced vibration. Otherwise the vibration can create uneven gaps between the springs and the upper plate, which will cause excessive mechanical noise.

Vibration Noise

VT003F's noise is a combination of sound wave noises and mechanical noise.

Sound wave becomes audible to human ears when the vibration frequency is about 20Hz. Sound wave noise is not avoidable.

noise of vibration

Mechanical noise is produced by the friction and impact between the moving parts of the vibration machine. It is also not avoidable, but could be reduced through design optimization, parts precision and assembly accuracy improvement.

As VT003F is designed for household use, we have been making a lot of efforts to reduce its mechanical noises, in order to achieve better user experience.

One of the major source of mechanical noise is the striking between the upper plate and the supporting springs, due to the gaps produced between these two components during vibration. This noise will be greatly reduced when user steps on the machine with body weight centered.

VT003F's noise level, at the highest vibration frequency and high amplitude setting, is between 59dBA and 65dBA, measure at 6 inches above the machine. This range is between the noise level of a dishwasher and a vacuum cleaner.

The Clunk Sound

When you switch the amplitude between Hi and Lo while the machine is running, you will hear a clunk sound. This is normal.

This strike does not do any hurt to the machine. It is not a problem.

Eccentric wheels

This sound is produced because eccentric wheel strikes the stop block when motor reversing its rotation direction. VT003F switches amplitude by reversing motor rotation direction to engage either 1 pair or 3 pairs of eccentric wheels.

In P3 mode, the machine automatically switches the amplitude multiple times in a session as programmed. Therefore, you will hear clunk sound each time when the amplitude is switched, and you know the amplitude is switched when you hear the sound.

Electromagnetic Fields (EMF)

Like other household electric appliances, VT003F produces electric and magnetic fields (EMF). EMF is actually two types of energy fields that are measured separately.

EMF exposure of VT003F

The machine's magnetic field strength increases as the machine's vibration frequency and amplitude increase. The maximum magnetic field strength measured at one foot above VT003F's upper plate is 1.3 milligauss at the highest intensity setting.

The electric field strength does not follow the change of frequency or amplitude. VT003F's electric field strength measured at one foot above the upper plate is 44 V/m.

The type of EMF generated by VT003F is called extremely low frequency, or ELF EMF. Scientists have not found this type of EMF poses any safety concern to human.

EPA advises that there is no clear scientific evidence that EMF affects health. EPA does not define a safe or hazardous level of EMF exposure.

Reader's discretion is advised.
