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 (horizontal black 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.
Along with the visual depiction are calculations for the following:
- Link lengths
- Instant center (intersection point)
- Anti-squat geometry percentage
- Axle angle change
Calculated data instantly updates automatically as the car moves.
Imaginary (dotted) lines also indicate the normal position of the links and their mounting holes, making it easy to visualize how much the chassis and links have moved. The imaginary lines can be turned on and off as desired.
Instant center location markers are shown for every possible combination of mounting holes, making it easy to instantly visualize all of the possible instant center locations for your setup. You can point at any instant center location marker and the pointed location's statistics are listed, including which hole combination generates this instant center location. And you can click on any instant center location, and the associated link mounting holes will be selected here and in the input page.
Specifications are entered in the input page.
You can graph 4-link suspension geometry as well.
