We are designing a bicycle – from geometry to suspension kinematics. For the kinematics calculations we wrote our own software, implemented directly in Siemens Designcenter NX.
Scope
- Bicycle geometry
- Suspension kinematics designed without compromise
- Our own kinematics software running in Siemens Designcenter NX
- A parametric model – changing a dimension rebuilds the model and recalculates the kinematics
Kinematics module in Siemens Designcenter NX
The module runs inside NX, on the same model as the frame geometry. It calculates the leverage ratio and its progression, anti-squat for all gears, anti-rise, pedal kickback, chain growth, the rear axle path, the instant centre and sag. We compare geometry variants side by side and animate the suspension through the full wheel travel.
Frame parts
The parametric model also produces frame parts, for example the head tube node with the top and down tube joints.
The project draws on our experience in series production of carbon fibre bicycle frames.
