Gears are one of the fundamental components in power transmission systems and among the most critical parts of complex mechanical assemblies. Especially in systems requiring high torque, speed, and precision, accurate analysis of gear behavior is essential for improving efficiency, durability, and overall performance. This is where RecurDyn comes in—offering advanced analysis capabilities engineers rely on.
With its physics-based modeling (MFBD), high-resolution contact simulation, and modular approach, RecurDyn allows for a comprehensive analysis of gear systems under real operating conditions.
The Gear Toolkit in RecurDyn enables users to model and analyze gear interactions accurately within multibody systems. Gears are not only analyzed kinematically but also under physical effects such as elastic deformation, contact forces, dynamic loading, and vibration behavior.
Supported Gear Types:
Spur Gears
Helical Gears
Bevel Gears
Worm Gears
Planetary Gear Systems
Internal/External Ring Gears
The Gear Toolkit enables multidimensional analysis of gear systems:
RecurDyn evaluates each gear pair individually to simulate contact surfaces and resulting pressures. This enables:
Load calculation per gear tooth
Visualization of contact stress distribution
Prediction of wear patterns and surface damage
Unwanted vibration and noise in gear systems often arise from micro-contact errors or misalignments. RecurDyn helps detect these issues and supports design improvements that mitigate such behaviors.
RecurDyn accounts for heat generation and lubrication effects, providing a more realistic simulation environment. Thermal expansion, oil film thickness, and viscosity variations can be integrated into the model.
The Gear Toolkit works with the MFBD environment in RecurDyn/Professional, allowing for gear flexibility. Integration with FEM tools like ANSYS provides enhanced accuracy for deformable components.
Manufacturing defects, backlash, and misalignments can be included in simulations to verify design tolerances and system robustness.
The RecurDyn Gear module is widely used across various sectors:
Manual and automatic transmissions
Differentials
Electric drive systems
Powertrain reduction gears
Rotating mechanisms in tank turrets
Weapon actuation systems
Gearboxes in armored vehicles
