Lower g-forces are much easier to tolerate and give the body a huge load. After all, the body was built to a gravity of 1g.Īnybody who has been on a high g-force machine will tell you how uncomfortable it is and how their stomach felt.

Death: if g-forces are not quickly reduced, death can occur.Īt 5g, race car drivers complained of being disoriented and dizzy ( ).Ī responsible manufacturer does not want his machine to be able to inflict such conditions.Īnother issue is long-term damage to organs.G-LOC: a loss of consciousness (“LOC” stands for “Loss Of Consciousness”).Blackout: a loss of vision while consciousness is maintained, caused by a lack of blood to the head.Tunnel vision: where peripheral vision is progressively lost.Grey-out: where the vision loses hue, easily reversible on levelling out.In aircraft particularly, vertical g-forces are often positive (force blood towards the feet and away from the head) this causes problems with the eyes and brain in particular.Īs positive vertical g-force is progressively increased (such as in a centrifuge) the following symptoms may be experienced : That amount of force causes fatigue, blackouts, even death as gravity drives blood and oxygen from the brain, lungs and heart.” Ref: Ī typical person can handle up to 5g (49 m/s²) (meaning some people might pass out when riding a higher-g roller coaster, which in some cases exceeds this point), but through the combination of special g-suits and efforts to train muscles-both of which act to force blood back into the brain-modern pilots can typically handle a sustained 9 g (88 m/s²). “Planes today are so fast and nimble that standard evasive maneuvers can add nine times the weight of gravity, or nine g’s, to the mass of a pilot’s body. Michael Behar, “Defying Gravity.” Scientific American. His machine is a vibration machine and not a death machine. So obviously, a manufacturer does not want his machine to go to 16g. Let us examine what is an ideal g-force from the point of view of a skilled responsible manufacturer.Ī constant 16g for a minute may be deadly (ref: ).

It is completely under the control of the manufacturer to achieve whatever frequency they deem to be ideal. In essence, if you want a higher g-force you use a bigger differential ratio, if you want a lower g-force you use a smaller differential ratio. To put it simply, G-force is a function of frequency hz.Hz is decided by the differential that the manufacturer uses. Vibration machines have the ability to multiply the g-force by varying the differential ratio, or up and down motion, of their machine. Three times is 3g, four times is 4g, five times is 5g – and so on. So if a force is twice the pull of the Earth, it is called 2g. As Vibration Technology is becoming more widespread we are finding that there is some confusion about Gforce – this needs to be clarified so that users of vibration machines are not misled.
