MASTA MODULES
MASTA consists of a core module and over 75 additional modules with additional design components and advanced analysis functionality. MASTA can be customized according to user-specific or industry requirements.
Functions of the Core Module
The core module provides a CAE environment for the design of transmission and transmission systems using shafts, bearings and cylindrical gears.
Design Features in the Core Module include the following;
- 2D and interactive 3D design environment
Comprehensive database of over 44,000 bearings defined in the catalogs of bearing manufacturers
Cylindrical gears, shafts, bearings, clutches, synchromesh, splined shafts, etc. can be added to the design environment.
Addable power and point loads, configurable load cases and operating speeds
Editable shaft profiles with importable 2D CAD drawings (.dwg / .dxf)
The Analysis Features in the Core Module include the following;
- Power flow
System deflection
Cylindrical gear loading and misalignment
Cylindrical gear strength analysis according to ISO 6336, DIN 3990 and AGMA 2101-D04
Bearing loading and misalignment
Bearing strength calculations according to ISO 76, ISO 281 and ISO/TS 16281
Shaft fatigue analysis and strength calculations according to DIN 743, AGMA or SMT
Macro geometry optimization for strength or contact ratio
Innovations in Expert Modules
The following summarizes the key updates in the latest version of MASTA. Please contact us for more details.
Full Finite Element Network Reduction and Analysis
-
A new module has been developed to import a complete finite element mesh (FE) for a body or shaft and then perform the necessary modifications to this model within MASTA. In addition, the results of stresses, deflections, mode shapes and energy content for the complete Finite Element model are displayed within MASTA.
The main features are:
Import of FE model into MASTA.
Creation of stiffness and mass matrices in MASTA.
View deflections, stresses and strains following the System deflection analysis in MASTA.
Extension of FE results to display mode shapes and modal energy content following NVH analysis.

Complete Finite Element Network Reduction and Analysis
-
- Inclusion of the rim and gear clearance in the FE model for advanced LTCA analysis
Tip contact analysis for both spur and helical gears, including the effect of an extended, stationary line of motion
Adding more analysis results to the contact chart
Fixing the Contact Chart scale to facilitate comparison of results
Run the LTCA analysis for only the first planet (i.e., first planet angle) and collect the results
- Inclusion of the rim and gear clearance in the FE model for advanced LTCA analysis
Intradental Fatigue Fracture (TIFF)
It allows users to estimate the risk of crack initiation for TIFF according to the MackAldener method. The module uses the results of MASTA’s Loaded Tooth Contact Analysis and visualizes internal stress and fatigue stress. Understanding such failure is becoming increasingly important for transmission development and system optimization can thus be done at the early stages of design.
Scraping Dynamics
It is a new module that provides simulation of the rasp force variation from gear tip to gear bottom according to the rasp method that determines whether the tooth profile will have additional step or profile error.
Simulation of the Hobbing Process
This newly revised and updated module takes into account the variety of static errors in the machining process for the hobbing operation. The process simulation module reproduces the gear geometry, including deviations, in accordance with production conditions.
Improved Gear Coefficient of Friction Options in Power Loss/Efficiency Calculation
New Coefficient of Friction calculation methods have been added in addition to the previously available ISO/TR 14179-1:2001 method.
Display of Gear Flank Loading Condition
Shows which area on the tooth flank is loaded. In Power Flow mode, lateral loading in 2D and 3D views can be visualized.
In other analysis modes, this option is used in 2D View.
Bevel/Hypoid Gear Misalignments.
In addition to the previous results calculated according to the cross point, a misalignment table calculated according to the gear mesh point can be added.
Improved CAD Reports.
CAD reports have been improved compared to previous versions and now offer the possibility to add more data and information in “CAD Gear Data Sheets”.
Images can be added with feature labels updated to reflect design/analysis values.
The CAD report template can be adjusted as desired.
Bearing Improvements.
In addition to the estimated factors, user-specified X, Y factors can also be included in the analysis for Dynamic Equivalent Load calculations for cylindrical roller bearings that can take axial loads.
LDP Import
Basic design can be imported from LDP. This initial implementation is limited to internal or external cylindrical gear pairs and only macro geometry data can be imported at this time.
FE Component Node Connection Report
Three new tables are available in the default report for an FE component imported in Design mode that show the expected and actual locations of FE nodes on the connected component to evaluate the accuracy of the imported FE.
Bearing Node Alignment with FE
For bearings, it is possible to determine whether FE nodes are created at the center of the bearing or the center of the bearing half.
This is particularly useful for bearings where half of the housing is not the full width of the housing, such as tapered roller bearings.
Cylindrical Gear Misalignment Calculation Methods
Cylindrical gear misalignment calculations can be performed based on alternative misalignment definitions.
AGMA Rating Using Calculated Values in LTCA
LTCA Stresses can be used when classifying gears according to AGMA 2101-D04 in Micro Geometry mode, by selecting the option under the AGMA rating options in the Cylindrical Gear Class section of Settings.
Source/Structural Factor
A new option is provided to specify the Source/Structural Factor, Xw, used in scuffing calculations.
