Gas Spring Force Calculator:
Enter the values of weight, W(N) in Newton metre applied to the gas spring, distance, X(m) moved by the gas spring, number, N of gas springs and distance, Y from the hinge point to the moving mounting point to determine the value of gas spring force, Fs(N).
Gas Spring Force Formula:
Gas spring force refers to the force exerted by a gas spring, a type of spring that uses compressed gas contained within a cylinder and compressed by a piston to exert a force.
Gas spring force, Fs(N) in Newton is calculated by dividing the product of weight, W(N) applied to the gas spring and distance, X(m) in metres moved by the gas spring by the product of number, N of gas springs and distance, Y from the hinge point to the moving mounting point.
Gas spring force, Fs(N) = W(N) * X(m) / N * Y
Fs(N) = Gas spring force, in Newton, N.
W(N) = weight applied to the gas spring in Newton, N.
X(m) = distance moved by the gas spring in metre, m.
N = number of gas springs.
Y = distance from the hinge point to the moving mounting point.
Gas Spring Force Calculation:
- Suppose you are designing a hatch cover that needs a gas spring for support. The hatch weighs 200 N, and you plan to use 2 gas springs. Each gas spring will compress by 0.5 metres when closed, and the system provides a mechanical advantage of 2. Calculate the force each gas spring must exert.
Given: W(N) = 200N, X(m) = 0.5m, N = 2, Y = 2.
Gas spring force, Fs(N) = W(N) * X(m) / N * Y
Fs(N) = 200 * 0.5 / 2 * 2
Fs(N) = 25N.
- For a tool lid that requires a lighter touch, the lid weighs 100 N. You decide to use a single gas spring, where the acquired gas spring force is 26.67N. The mechanical system designed offers a leverage factor of 1.5. Determine the distance moved by the gas spring.
Given: W(N) = 100N, , N = 1, Y = 1.5, Fs(N) = 26.27N.
Gas spring force, Fs(N) = W(N) * X(m) / N * Y
X(m) = Fs(N) * N * Y / W(N)
X(m) = 26.67 * 1 * 1.5 / 100
X(m) = 0.4m.
