A-arm Suspension Geometry Simulation
Vehicle travel and roll is simulated by dragging the image with the mouse, or with scroll bars.
As you move the car with the mouse (or the scroll bars), the chassis outline (blue lines) move up and down and rolls from side to side in response. Along with the movement of the chassis, the inner suspension pickup points move, and the outer ones move correspondingly. The tires also move along with the outer suspension joints. Imaginary (dotted) lines illustrate the kingpin axis (gray), the instant centers (red), and the roll center (white).
Along with the visual depiction are calculations for the following:
- Roll angle
- Ground clearance
- Instant center and roll center for each side
- Roll center horizontal and vertical position
- Kingpin angle and offset for each side
- Camber angle for each side
- Track width
Calculated data instantly updates automatically as the car moves.
Imaginary (dotted) lines also indicate the tire's normal position, making it easy to visualize how much the tire has moved. All of the imaginary lines can be turned on and off individually.
Specifications are entered in the A-arm input pages and the travel input page.
You can graph suspension movement by travel or roll.
