GT-3DMBD Machinery
From gear stress to system noise — one geartrain workflow.
PRODUCT OVERVIEW
What is GT-3DMBD Machinery?
GT-3DMBD Machinery allows analysis for NVH and durability/losses in automotive geartrain systems such as transmission, differential, xEV gearbox, timing and auxiliary drives. However, functionality is applicable to any machinery or machine subsystem such as wind turbine transmissions, marine drivelines, helicopters and power transmission and reduction systems in industrial machinery.
ENHANCED MACHINERY MODELING
Understand Complex Machinery
GT-3DMBD Machinery is a set of modeling elements aimed at the dynamic modeling of machinery involving shafts, cylindrical and bevel gears, together with flexible bearing and gearbox structural models, to address powertrain loss and NVH issues with higher fidelity.
Advanced Features
Geartrain Modeling Capabilities
Advanced Gear Contact Modeling
Model gear tooth contact at macro and micro levels to capture stress, transmission error, and surface geometry effects that drive NVH and durability outcomes.
Gear Contact Tribology
Predict friction, wear, and meshing losses at the gear tooth interface using physics-based tribology models. Supports both fast and detailed contact formulations.
Machinery Loss Modeling
Quantify mechanical losses across the full geartrain system to support efficiency optimization and thermal management decisions.
Hydrodynamic Bearing Models
Apply hydrodynamic film models to thrust bearings and bushings for accurate load capacity and friction predictions under operating conditions.
Vehicle System Integration
Connect geartrain models directly to full vehicle dynamics models to evaluate system-level NVH, load transfer, and driveline behavior in context.
3D Geartrain Modeling
Build and visualize complete geartrain or drive system models in a dedicated 3D environment, reducing setup time and improving model confidence.
Multi-physics Integration
Couple mechanical geartrain models with hydraulic, electromagnetic, or e-drive systems — including JMAG — for high-fidelity system-level analysis.
Use Cases
-
Full Geartrain Analysis
GT-3DMBD Machinery offers a comprehensive workflow for geartrain design. From the tooth design to the gear stress to the NVH analysis, GT-3DMBD Machinery allows the engineer to study all aspects of the geartrain.
-
Understand Gear Stress
With GT-3DMBD Machinery’s advanced gear contact models, a user is able to model the stresses within many gear designs. This allows the engineer to have a better designed geartrain that is more reliable and higher performing.
