4-Link Suspension Geometry Simulation
Vehicle travel is simulated by dragging the image with the mouse or with a scroll bar.
As you move the car with the mouse (or the scroll bar), the chassis base (blue line) moves up and down in response. Along with the movement of the chassis, the front link attachment points move, and the rear ones move correspondingly. The axle also moves along with the rear suspension joints. Imaginary (gray dotted) lines illustrate the static (ride height) position of the arms.
Along with the visual depiction are calculations for the following:
- Link lengths
- Instant center (intersection point)
- Axle angle change
Calculated data instantly updates automatically as the car moves.
Imaginary (dotted) lines also indicate the normal position of the links, making it easy to visualize how much the chassis and links have moved. The imaginary lines can be turned on and off as desired.
Specifications are entered in the input page.
You can graph 4-link suspension geometry as well.
