Kitchen cabinet flap
Set the tension springs on a six-bar hinge so that a 2–8 kg flap opens by itself from about 15–20°. ASOMmini shows the manual force curve.

Four-bar linkage with manual force
Wherever a person moves a mechanism by hand, the required manual force matters. ASOMmini shows it over the entire motion with the manual force element.

The task
How much force does the hand need?
A four-bar linkage is moved by hand at its coupler. The motion is specified: forward, dwell, back, dwell. The task is to find the manual force required at every moment – even if the bearings, application point or center of gravity are still subject to change.
What ASOM shows here
- The manual force element shows the required holding force at all times – even during the dwells.
- A diagram shows the manual force over time, with X and Y components.
- Move the application point, a bearing or the center of gravity, and ASOMmini immediately shows the new force curve.
Your benefits
Know the manual force before anything is built
From the start, you see how much force a person has to apply – and how every change affects it.
Clarify ease of operation early
You see whether the manual force remains comfortable and move the application point until it is right. More on force calculation
With mass and friction
Centers of gravity and friction in the joints feed directly into the manual force.
Reach a good solution faster
You try out many variants instead of committing to one early on.

Where should the hand apply force? ASOMv10 shows the manual force for many application points at once in one diagram – even while you move the points.
