FULL FE MESH REDUCTION AND ANALYSIS

  • New module for import a full FE mesh of a housing or shaft and then perform a condensation on this model within MASTA
  • Results for the full FE model may be expanded in MASTA to view stresses, deflections, mode shapes and energy content
  • Key features include:
    • Importing Full FE models to MASTA
    • Performing stiffness and mass reduction in MASTA
    • View deflections, stresses and strains following a System Deflection analysis in MASTA
    • Expand FE results to view mode shapes and modal energy content following an NVH analysis in MASTA

TOOTH INTERIOR FATIGUE FRACTURE (TIFF)

Allows users to predict crack initiation risk for TIFF based on the method of MackAldener. The module uses results from MASTA’s Loaded Tooth Contact Analyses and visualises the internal stress and fatigue stress.

Understanding of such a failure is becoming more essential to transmission development and optimisation can now be made early on in the design stage.

LOADED TOOTH CONTACT ANALYSIS ENHANCEMENTS

A number of developments have been included regarding MASTA’s Loaded Tooth Contact Analysis. In particular:

  • Including the effect of extended, off line of action, tip contact for both spur and helical gears
  • Including the rim and web in the FE model for Advanced LTCA analyses
  • Adding a number of further analysis results to the contact chart
  • Additionally it is now possible to fix the Contact Chart scale to facilitate comparison between results
  • A new option is available to run the LTCA analysis only for the first planetary mesh (i.e. the first planet angle)

MORE FEATURES

Plunge Shaving Dynamics

A new module that enables simulation of the shaving force variation from the gear tip to root according to the shaving method, which determines whether the tooth profile will have additional profile/lead error

Hobbing Process Simulation

This newly revised and updated module considers the variety of static errors in the machining process for gear hobbing. The process simulation module can reproduce the gear geometry, including deviations, under the manufacturing conditions

Enhanced Mesh Coefficient of Friction Options for Power Loss/Efficiency Calculation

New Coefficient of Friction calculation methods are now available in addition to the previously available ISO/TR 14179-1:2001 method

Gear Flank Loading INDICATOR

Indication of which are the loaded gear flanks. In Powerflow mode you can visualise flank loading in both 2D and 3D Views. In other modes the option is available in 2D View

Inclusion of the Effect of Shot Peening on ISO Calculated Gear Bending Stresses

For ISO gear materials specify that a material is shot peened and then specify a Shot Peening Bending Stress Benefit percentage for inclusion in the gear rating

Gear Tolerance Standards

  • When performing cylindrical gear rating to AGMA 2101-D04 it is now possible to specify to use the AGMA 2000-A88 and ANSI/AGMA ISO 1328-1-B14 Tolerance Standards in addition to the existing AGMA 2015-1-A01 standard

Bring in basic design from LDP. This initial implementation is limited to internal or external cylindrical gear pairs and only macro geometry is currently imported.

FE Component Node Connection Report

Three new tables are included in the default report for an imported FE component in Design mode that show the expected and actual locations of the FE nodes on the connected component as an aid to assess the accuracy of the imported FE

Bearing Node Alignment with Imported FE

Specify whether FE condensation nodes for the bearings have been created at the centre of the bearing or at the centre of the bearing race. This is especially useful for bearings such as taper roller bearings where the race of the bearing is not always the full width of the bearing

Cylindrical Gear Misalignment Calculation Methods
