Aircraft landing gear with bearing friction
How much does joint friction change the cylinder force during extension and retraction? ASOM shows the force with and without friction in one diagram.

Kinematics of a truck lift gate
Two hydraulic cylinders move the lift gate of a truck through several partial movements all the way down to the road. ASOM plays back the entire motion sequence in one model and calculates the bearing forces with friction.

The task
Several partial movements, one complete sequence
The lift gate is designed as a linkage with two degrees of freedom, driven by two hydraulic cylinders. Its motion is made up of partial movements: opening, transition to the horizontal, raising and lowering the platform, and lowering the loading edge onto the road. For each position, the key figures are the required cylinder lengths and the bearing forces.
What ASOM shows here
- The advanced drive control operates both hydraulic cylinders and combines the partial movements into one complete motion sequence.
- ASOM calculates the bearing forces including friction and displays them graphically.
- Change the mechanism, and the cylinder lengths and bearing forces adapt immediately.
Your benefits
Motion sequence and bearing forces in one model
You see early on which cylinder lengths are required and which forces the bearings absorb – and how every change affects them.
A sequence instead of single positions
Instead of examining each position individually, you run all partial movements in one model. More on motion sequences
Choose the right cylinders and bearings
You know the cylinder lengths and bearing forces before cylinders and bearings are selected. More on force calculation
Compare variants directly
You check a modified mechanism in the same model, without starting over.
