Roll

Spring

This motion ratio is chassis roll angle divided by spring displacement (e.g. a ratio of 0.5 means that for every 1 deg/rad of roll the spring will displace by 2mm/in). The chassis roll is the roll motion that is applied to the chassis. The spring displacement is measured along the axis of the spring (line drawn from spring attachment to chassis points). This motion ratio is calculated at each step of the simulation by rolling the chassis by a given amount and then calculating the motion ratio based on the spring displacement.

Damper

This motion ratio is chassis roll angle divided by damper displacement (e.g. a ratio of 0.5 means that for every 1 deg/rad of roll the damper will displace by 2mm/in). The chassis roll is the roll motion that is applied to the chassis. The spring displacement is measured along the axis of the spring (line drawn from spring attachment to chassis points). For coilovers the damper axis is a line drawn from spring attachment to chassis points. This motion ratio is calculated at each step of the simulation by rolling the chassis by a given amount and then calculating the motion ratio based on the damper displacement.

ARB - Dist

This motion ratio is chassis roll divided by anti-roll bar displacement (e.g. a ratio of 0.5 means that for every 1deg/rad of chassis roll the anti-roll bar will displace by 2mm/in. The chassis roll is the roll motion that is applied to the suspension. The anti-roll bar displacement is the total displacement of the lever arm(s). This motion ratio is calculated at each step of the simulation by rolling the chassis by a given amount and then calculating the motion ratio based on the anti-roll bar displacement.

ARB - Angle

This motion ratio is chassis roll angle divided by anti-roll bar Angle (e.g. a ratio of 0.5 means that for every 1 deg/rad of roll the anti-roll bar will rotate by 2 deg/rad. The chassis roll is the roll motion that is applied to the chassis. The anti-roll bar angle is the rotation displacement of the anti-roll bar’s lever arm around the shaft. This motion ratio is calculated at each step of the simulation by rolling the chassis by a given amount and then calculating the motion ratio based on the anti-roll bar angular displacement.
