Romax Technology has recently is currently launching it's latest software package release R12.6. The software package includes RomaxDesigner, RomaxDurability, RomaxDynamics and RomaxNVH.
The new edition includes a completely new industry specific application called RomaxWIND, a number of additional features within RomaxDurability and numerous enhancements and updates across the entire package.
Development of RomaxDesigner is continuous and R12.6 sees a myriad of enhancements to everyday usability including automatic compression of design files, which not only saves disk space but also allows designs to be easily emailed or shared. There are improvements to the speed of loading and saving files, FE analysis of large models and faster generation of reports. The latest version also incorporates a range of new catalogue data for materials including the addition of the complete Koyo bearing database.
ANSol and SIMPACK interfaces
R12.6 includes new module BS08 ANSol Interface which interfaces with Advanced Numerical Solutions (AnSol) software for FEA-based loaded tooth contact analysis of hypoid gears. This enables hypoid gear transmission error results to be returned to Romax software for further use in NVH and dynamic analyses of the system.
The new addition of RomaxWIND includes provides interfaces to common analysis tools used up and downstream in the design such as new module SIMPACK Model Export. Users can also now create a SIMPACK ® dynamic model directly from a RomaxDesigner model. This allows bearings to be esported as simple bushings or as full Romax bearings within SIMPACK.
Extended and improved modules
The following modules have been significantly extended and improved within R12.6:
Static analysis changes
-
Updated settings dialog - the analysis settings are now grouped by function and include the gearbox transmission error and NVH settings
-
Option to not store convergence data - saving memory when saving models
-
Convergence improvements - improved clearance bearing contact load integration has been included to mimimise the liklihood of non-convergence issues
-
Effects of tooth micro-geometry for static calculation
Modelling
-
A Koyo bearing catalogue has been added
-
Updated material database for shafts, bearings and housings
-
Concept hypoid sizing feature - allows the design of concept hypoid gear sets when only they input torque, drop and gear ration are known
Reporting
-
3D deflected results scaling - both Cartesian and Cylindrical coordinates can be used to scale deflected results
-
A component cutaway tool is now available in any 3D worksheet allowing any component to be cut away
-
Tooth chamfers are now visible in both the 2D gear profile and the 3D gear visualisation
-
3D connextion 3D Mice are now supported in the 3D views
Design of Experiments (DoE)
A new sensitivity analysis method has been added to the DoE module. This allows user to quickly assess the sensitivity of a target to any number of variables in a parametric study. The results give valuable information about the robustness of a design, as well as indicating design changes which could be made to improve performance.
RomaxDurability
The reliability of a gearbox can be predicted in R12.6. A full breakdown of the probabilities of failure for all gears and bearings in a system is reported allowing critical components in the design to be identified.
A new feature in R12.6 allows users to import a set of recorded time history or duration data and use it to generate a representative duty cycle or analysis.
RomaxWIND
A specially tailored interface allows users to quickly input wind turbine load data in industry standard formats. A wind turbine load set consisting of load distribution data (LDD) and extreme load cases can be easily defined and analysed.
RomaxWIND provides an “all-in-one” software tool tailored for wind turbine applications and encompasses the design, sizing and optimisation of drivetrain systems. Using a unique approach to planetary gear simulation, RomaxWIND is able to produce in-depth results for deflections, alignments, vibration and dynamic response of wind turbine gearboxes in record time. This accuracy and speed enables complex numerical simulations to be performed up front in the design cycle, so that system interactions between the gearbox, drivetrain and turbine can be considered in full.
System and licensing changes
The time taken to generate a duty cycle report has been reduced up to 70% in some cases and the time taken to load and save models has also been reduced.
Other changes include:
-
compressed model files
-
improved memory management
-
reduced initial memory requirements
-
improved handling of large FE models
-
SafeNet licensing
