The developer does not include self-directed tutorials with the software, but the company really does provide user training directly. The trainers customize course content material and duration to meet the needs of each organization. A one-week work out would be enough to cover the basic modules and some advanced topics. Many extremely specialized software packages require constant make use of to become and stay proficient. I discover that RomaxDesigner does not require this level of attention. Engineers with other responsibilities will see this software functional even if not used on a regular basis.

For parallel and perpendicular-axis gears, modules provide interfaces to more descriptive analysis software, such as for example Simpack, LDP, and AnSol. They become a “front end” for even more-computationally intensive formulations of bending and contact stress. The combination of these software packages is particularly powerful, since it permits cumulative harm-life analysis like the nonlinear ramifications of gear-tooth deflection and bearing stiffness, acting on a fully developed tooth profile. Additional modules concentrate on NVH and powerful characteristics, such as equipment rattle and whine, program modal evaluation, and clutch evaluation. Modules are also open to automate optimization and for the sensitivity analysis of system and component designs.

RomaxDesigner models can include spur and helical gears, and with the perpendicular-axis module, bevel and hypoid gears. The base software models gears with enough detail to investigate their effects on all of those other system. Additional modules allow style and ranking to AGMA, DIN and ISO standards. For parallel-axis gears, extra modules permit macrogeometry definition and optimization for manufacturability along with detailed analysis of microgeometry for contact stress and transmission error. RomaxDesigner graphics are suitable for a variety of reporting illustrations, such as system topology and component deflection.

Bearing models provide non-linear stiffness interactions with adjacent parts, which may be critical when calculating gear-support stiffness, gear-mesh misalignments and preload requirements. When calculating bearing lifestyle, the models include the results of misalignments developed through the flexibility of any coupled components. A bearing preload device automates research of bearing life since a function of preload. These features have been proposed for a future release.
Advanced bearing-analysis modules offer detailed analyses (ISO 281 Health supplement 4), including contact tension, fluid-film thickness, and stress-based life calculation. Advanced bearings can be defined with a variety of predefined roller and raceway crowns, or with a measured crown.
