Member Function Documentation

virtual void chrono::vehicle::ChAntirollBar::Initialize ( std::shared_ptr< ChBodyAuxRef chassis,
const ChVector<> &  location,
std::shared_ptr< ChBody susp_body_left,
std::shared_ptr< ChBody susp_body_right

Initialize this anti-roll bar subsystem.

The anti-roll bar subsystem is initialized by attaching it to the specified chassis body at the specified location (with respect to and expressed in the reference frame of the chassis). It is assumed that the suspension reference frame is always aligned with the chassis reference frame. Finally, susp_body_left and susp_body_right are handles to the suspension bodies to which the anti-roll bar's droplinks are to be attached.

Parameters
[in]chassishandle to the chassis body
[in]locationlocation relative to the chassis frame
[in]susp_body_leftsusp body to which left droplink is connected
[in]susp_body_rightsusp body to which right droplink is connected

Implemented in chrono::vehicle::ChAntirollBarRSD.
