Advanced Spring Dynamics
Spring dynamics with distributed mass, stiffness and coil contact.
GT-SUITE provides many tools to the valvetrain engineer, from single valvetrain layout and kinematics to full multi-cylinder camshaft dynamics
Solution Overview
Optimal Tool for Valvetrain Engineers
Contact stress, spring fatigue, and friction can be analyzed at multiple levels of fidelity. What sets GT-SUITE apart is the ability to quickly scale the scope of the model as needed.
Since the camshaft model is built from the same building blocks as the crankshaft, that means bearing, torsional and bending analysis is built in. Flexible finite element bodies can be added to replace rocker arms or swing cams. Mechanical valves can even natively link to engine flow valves in a one-step process.
Application Highlights
Advanced Valvetrain Modeling and Analysis
- Models conventional and variable lift mechanisms
