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.

Friction on an inclined plane
A block on an inclined plane shows on a small scale how ASOMv10 incorporates friction into a kinematic model instead of neglecting it.

The task
How much force holds the block?
A block is moved on an inclined plane. How much holding force this requires depends on the friction between block and plane – and on whether the block is raised or lowered.
What ASOM shows here
- You specify the friction between block and plane with the friction coefficient μ.
- The holding force appears in the diagram for raising and lowering, each with and without friction.
- Using constraints such as the angle of inclination, you change the model in a targeted way and check its behavior across wide parameter ranges.
Your benefits
Factor in friction from the start
You include friction right away and immediately see how the required force changes with the parameters.
Forces you can rely on
With friction factored in, you do not undersize drives and holding forces. More on force calculation
Many cases, little effort
Instead of recalculating individual cases, you test many inclinations in a short time. More on constraints
A basis for larger models
You use the same slider friction in any mechanism with sliders and rails.

Hospital bed with spindle drives
Two drives that model spindle drives adjust the height and the foot section. ASOMv10 calculates drive and bearing forces in real time, with friction in all joints and guides.
