Tailgate with gas springs
Two gas springs whose force depends on temperature and direction, plus a parcel shelf on a cord. ASOMv10 shows all manual forces for opening and closing in one diagram.

Kinetostatic sensor field
Where should the manual force be applied? ASOMv10 calculates 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. The principle can be applied to any other multi-bar linkage.
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.
- If needed, you extend the analysis, for example to the bearing forces.
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 recalculating 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 conceptual design.
Transferable
The principle works for any multi-bar linkage. More on forces in the model

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