 Valvetrain Kinematics & Dynamics |
GT-VTRAIN is a multi-purpose simulation tool for the mechanical design analysis of valvetrain systems. It has a well proven and validated track record and performs, in a single environment, the following valvetrain analysis functions:
 |
Cam design |
|
Valvetrain mechanism kinematics |
|
Quasi-static rigid analysis, with all inertias plus valve springs; computes all forces, separation speeds |
|
Valvetrain multi-body dynamics |
|
Contact (e.g. cam-follower) tribology: Hertzian stress, deformation, oil film thickness, wear load |
|
Valvetrain frictional forces and power loss |
|
Camshaft torsional vibrations (time/freq. domain) |
|
Camshaft bending dynamics |
|
Camshaft bearing orbits, friction torques |
|
Gear, chain and belt drive dynamics |
GT-VTRAIN models can be run stand-alone, or together with coupled models of cranktrain (GT-CRANK) and of fuel injection (GT-FUEL).
