How to get current speed when using kinematics

When I use the kinematics to make a customized Basic TE , I want to get its current speed of one axis at any time . What is the command I can use to get the speed ?

FlexSim 18.2.0
speed
5 |100000

Hi Shiny Xu,

Use the getkinematics() command.

getkinematics(kinematicnodereference,KINEMATIC_VX); // for speed along x-axis
getkinematics(kinematicnodereference,KINEMATIC_VY); // for speed along y-axis
getkinematics(kinematicnodereference,KINEMATIC_VZ); // for speed along z-axis

Regards,

Arun KR

Thank you very much. Can I get the current speed of a ASRSvehicle and its every axis?

Yes. You have to look at two kinematic nodes in the ASRS vehicle tree and they are forkkinematics and kinematics. So your code will look like this.

treenode kinematics = Model.find("ASRSvehicle1>variables/kinematics");//along the slider
treenode ForkKinematics = Model.find("ASRSvehicle1>variables/forkkinematics");//extender, up and down movement
double Vx = getkinematics(kinematics,KINEMATIC_VX);
double Vy = getkinematics(ForkKinematics,KINEMATIC_VY);
double Vz = getkinematics(ForkKinematics,KINEMATIC_VZ);
print(Vx,Vy,Vz);
