Driveline gearboxes

The developer does not include self-directed tutorials with the software, but the company really does provide user training directly. The trainers customize course articles and duration to meet the needs of each organization. A one-week training session would be sufficient to cover the basic Driveline gearboxes modules and a few advanced topics. Many highly specialized software packages require constant make use of to become and stay proficient. I find that RomaxDesigner will not require this level of attention. Engineers with other responsibilities will see this software functional even if not applied to a regular basis.

For parallel and perpendicular-axis gears, modules provide interfaces to more descriptive analysis software, such as Simpack, LDP, and AnSol. They become a “front end” for also more-computationally intensive formulations of bending and get in touch with stress. The combination of these software packages is particularly powerful, as it permits cumulative damage-life analysis including the nonlinear effects of gear-tooth deflection and bearing stiffness, functioning on a fully developed tooth profile. Extra modules concentrate on NVH and powerful characteristics, such as equipment rattle and whine, system modal analysis, and clutch evaluation. Modules are also open to automate optimization and for the sensitivity evaluation 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 the rest of the system. Extra modules allow style and rating to AGMA, DIN and ISO criteria. For parallel-axis gears, extra modules permit macrogeometry definition and optimization for manufacturability and also detailed evaluation of microgeometry for get in touch with stress and transmission error. RomaxDesigner graphics are suitable for a number of reporting illustrations, such as system topology and element deflection.

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