Front view geometry and roll center height 1

Given data:

Track width=1600 mm

Tire radius=300mm

Assumption:

1. The setup consists of links rather than control arms.

2. Origin point (0,0) is the center of tire contact patch of the left wheel in the front view.

3. Only Y-Z plane is under consideration.

Hardpoints:

UCA Knuckle ball joint (105,425)

UCA Subframe pivot point (285,460)

LCA Knuckle ball joint (105,185)

LCA Subframe pivot point (370,170)

Solution:

INSTANT CENTER COORDINATES:

LEFT WHEEL (-850,227)

RIGHT WHEEL (2450,227)

Note:Instant center for right wheel is obtained by adding the track width and Front View Swing Arm length i.e., 1600+850=2450.

Z-coordinate remains the same(227).

ROLL CENTER COORDINATES:

(800,-216)

Negative sign indicates that the roll center is below the ground plane.

ROLL CENTER HEIGHT = 216mm.
