1 – Gas spring pressure/force
The pressure required for the gas spring is calculated by substituting the values used in the following formula:
F1 = ((m x RH)/(2 x N x x2) + 5) x 9.81 = gas spring pressure expressed in Newtons
The number 5 represents a constant force of 5 kg/p, equivalent to rubbing actions.
For a hatchback with the following characteristics and values:
F1 = ((50 x 1.5) / (2 × 2 × 0.40) + 5) = 9.81 x 508N
In this case, since the tolerance is +/- 50 N, we would recommend two 550N gas springs.
