Two-sided silent chains and timing belts
Model drives that engage components on both sides of the belt or chain, capturing the full mechanical picture for complex accessory layouts.
Solutions
Timing and Auxiliary Drives
Model static layout and dynamic response of timing chains, belts, gears, and tensioners in a single GT-SUITE model, so you can catch bearing loads, torsional vibration, and NVH issues before hardware testing.
SYSTEM-LEVEL LAYOUT & RESPONSE ANALYSIS
Timing and accessory drives have traditionally been designed separately from the crankshaft and camshaft. But it’s become clear that how these drives respond dynamically can have a real impact on overall powertrain behavior.
GT-SUITE brings static layout and dynamic response analysis together in one model, so engineers no longer need separate tools for each. Timing and auxiliary drive models can be linked directly to existing crankshaft and camshaft models, making it possible to study bearing loads, torsional vibration, and bending effects as part of a single, integrated simulation.

Advanced Modeling Capabilities
Hydraulic and mechanical tensioners
Simulate how tensioning systems respond under real operating conditions, including start-stop events and speed transients, not just steady-state assumptions.
Flexible gear modeling, from simple to fully detailed
Choose between lumped/Hertzian contact for quick studies or fully flexible helical, bevel, and hypoid gear models when you need higher fidelity.
Compound gear-chain-belt systems
Combine gears, chains, and belts in a single model to represent drive systems the way they're actually built, without stitching together separate tools.
Belt slip and hub load analysis
Catch slip conditions and hub loading issues early, before they show up as durability or NVH problems downstream.
Steady-state and fully transient simulation
Run everything from quick steady-state checks to full transient events like speed ramps and start-stop cycles, all in the same environment.
