Wankel engine variants
Rotors with three to six apexes compared, each with the matching gear ratio. The trajectories of the rotor apexes form the housing contour.

Simulation of a Wankel engine
A Wankel engine with a triangular rotor: ASOMv10 simulates the motion and shows the matching housing contour.

The task
One rotor, three apexes, one contour
The pinion on the housing and the internal gearing of the triangular rotor must maintain a constant ratio of 2 : 3. Nevertheless, it should be possible to change the eccentricity, the rotor size and the curvature of the flanks freely. The matching housing contour should result from the motion – exact or with an offset for an apex seal.
What ASOM shows here
- The ratio of gear to ring gear stays constant at 2 : 3 with every change.
- The trajectories of the rotor apexes form the housing contour – exact or with an offset for an apex seal.
- Handles marked in red change the eccentricity, rotor size and curvature of the flanks – with the mouse or by entering a value.
Your benefits
Change the rotor shape, and the kinematics stay consistent
You change the eccentricity and rotor shape directly on the model; ASOMv10 keeps the system consistent and immediately shows the matching housing contour.
Nothing to adjust by hand
The system stays consistent with every change. More on constraints
Compare shapes quickly
A different rotor shape is set up quickly, and you see the matching contour immediately.
Switch the motion
You set up other motion sequences in the drive control by switching connections. More on motion sequences

Symmetrical six-bar linkage for a door
A six-bar linkage guides a door, with the joints arranged symmetrically. The synthesis is built from constraints alone, and the start and end positions remain adjustable.
