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
- From cam profile concept to high-RPM sign-off. What sets GT-SUITE apart is the ability to quickly scale the scope of the model as needed.
- Kinematic analysis delivers instant insight into valve motion and generate cam profiles.
- Fast quasi-dynamics predicts contact stress, valve float, spring surge, and dynamic loads across the full speed range in seconds.
- Full multi-body dynamics with detailed contacts captures spring dynamics, component compliance, valve bounce and dynamic lift, and seating behavior for final validation.
- Full integration with GT-POWER model, closes the performance and durability optimization loop.
- One model, three fidelity levels — faster iteration early, full confidence at sign-off.
