CALCULATION OF THE THRUST

To calculate the thrust of a gas spring in relation to the application, the formula given below should be applied.

F1 = ( ( M x D ) : L ) : nm ) + ( 10% ~ 15% )

The result should be increased by 10-15%, since the thrust vector of the spring is not parallel to the direction
of the weight vector of the object to be lifted and also to compensate for any friction in the system which
would detract from the efficiency of the thrust of the spring.

F1 = Thrust force of the spring which opposes the weight of the object to be moved, shown as vector;
M = Weight in kg of the object to be lifted, shown as vector;
B = Point of application of the weight of the object to be lifted; it corresponds to the centre of gravity;
C = Point of attachment of the gas spring to the mobile part;
S = Point of attachment of the gas spring to the fixed part;
O = Fulcrum and point of rotation of the mobile object;
D = Distance in mm measured horizontally between the centre of gravity B and the point of rotation O;
L = Length in mm of gas spring working arm corresponds to the least distance between the attachment S or the attachment C and the centre of rotation O; most of the time it is equal to the stroke of the gas spring and in any case cannot be greater;
nm = Number of springs to be used in the application (1 or 2 or more).
