Tailgate with gas springs
Two gas springs whose force depends on temperature and direction of motion, plus a parcel shelf on a cord. ASOM shows all manual forces for opening and closing in one diagram.

Kinetostatic sensor field
Where should the manual force be applied? ASOM calculates it for many possible application points at once.

The task
Where should the hand ideally apply force?
On a four-bar linkage, many possible application points for the manual force, arranged as a field, are to be compared.
What ASOM shows here
- Many manual force curves at once and in real time, compactly in one diagram window; each graph belongs to one application point.
- The application points can be moved individually or as a group at any time.
Your benefits
Compare variants at a glance
You see the manual force for all application points side by side and decide early on where the force should be applied.
Find the ideal spot faster
Instead of calculating point by point, you immediately see where the manual force curve is most favorable. More on force calculation
Clarify ergonomics early
You decide where the handle should go as early as the conceptual design stage.
Transferable
The principle works for any multi-bar linkage, and the analysis can be extended as needed, for example to include the bearing forces. More on forces in the model

Manually operated car seat
A hand lever adjusts the seat stroke by stroke. ASOM plays back the strokes automatically and shows the manual force for different seat occupancies in one diagram.

Joint friction
How much force is lost to friction? With a pin diameter and a friction coefficient for each joint, you compare manual and joint forces with and without friction.
