SMT MASTA (Smart Manufacturing Technology’s MASTA) is a comprehensive CAE (Computer-Aided Engineering) software suite specialized in the design, simulation, and analysis of mechanical transmission systems, including gearboxes, drivelines, gears, shafts, bearings, and splines. It supports the full product lifecycle from conceptual design to manufacturing optimization, with a focus on NVH (Noise, Vibration, Harshness), durability, efficiency, and performance prediction. Version 14.1.3 is a maintenance build within the MASTA 14 series (initially released in 2024), emphasizing enhanced stability, bug fixes for meshing and solver performance, and minor refinements to EV-specific modules. As of November 2025, MASTA 14 remains actively supported, with MASTA 15.0 available for new deployments; 14.1.3 is ideal for users on legacy setups requiring compatibility with older hardware or workflows. The software’s C#-based architecture ensures long-term stability across OS updates.
Key Features
- Core Functionality: Integrated 3D CAD modeling, quasi-static and dynamic simulations (e.g., LTCA – Loaded Tooth Contact Analysis, system deflection), and optimization tools for gears, bearings, and housings.
- NVH & Dynamics: Harmonic analysis with full acoustic post-processing; torque slice methods for speed-varying stiffness; per-tooth spline contact modeling in DRIVA (multibody dynamics module).
- EV/HEV Support: Import of torque ripple and stator loads from third-party tools; hairpin winding designs for electric motors; whine noise optimization via gear blank tuning.
- Advanced Modules: Over 75 optional modules, including MA129 (High-Speed Ball Bearing Analysis – Dynamic, with 6DOF per ball and cage modeling); TIFF crack initiation prediction (MackAldener method); friction calculations per ISO/TR 14179-1:2001 and new methods.
- New in v14 Series (Including 14.1.3 Fixes): Integrated acoustics (no external exports needed); out-of-core LTCA meshing solver; efficiency enhancements; floating RLM licenses; C# console app generation; flank loading visualization in 2D/3D.
- Deployment: Modular licensing (core + add-ons); supports hybrid workflows with tools like JMAG for electromechanical integration; export to ANSYS, Simcenter for FEA.
