The developer does not include self-directed tutorials with the program, but the company does Driveline gearboxes provide user training directly. The trainers customize course articles and duration to meet the needs of every organization. A one-week training session would be adequate to cover the basic modules and some advanced topics. Many extremely specialized software programs require constant use to be and stay proficient. I find that RomaxDesigner will not require this level of attention. Engineers with other responsibilities will find this software functional actually if not applied to a regular basis.
For parallel and perpendicular-axis gears, modules provide interfaces to more detailed analysis software, such as Simpack, LDP, and AnSol. They act as a “front end” for even more-computationally intensive formulations of bending and contact stress. The mixture of these software packages is particularly powerful, as it permits cumulative damage-existence analysis including the nonlinear effects of gear-tooth deflection and bearing stiffness, acting on a completely developed tooth profile. Additional modules concentrate on NVH and powerful characteristics, such as gear rattle and whine, system modal evaluation, and clutch analysis. Modules are also available to automate optimization and for the sensitivity evaluation of system and element designs.
RomaxDesigner models may include spur and helical gears, and with the perpendicular-axis module, bevel and hypoid gears. The bottom software versions gears with enough detail to investigate their effects on all of those other system. Extra modules allow design and ranking to AGMA, DIN and ISO specifications. For parallel-axis gears, extra modules permit macrogeometry definition and optimization for manufacturability in addition to detailed evaluation of microgeometry for contact stress and transmission mistake. RomaxDesigner graphics are suitable for a variety of reporting illustrations, such as for example system topology and element deflection.
Bearing models provide non-linear stiffness interactions with adjacent elements, which may be critical when calculating gear-support stiffness, gear-mesh misalignments and preload requirements. When calculating bearing existence, the models are the effects of misalignments developed through the flexibility of any coupled elements. A bearing preload device automates studies of bearing life because a function of preload. These features have been proposed for another release.
Advanced bearing-analysis modules provide detailed analyses (ISO 281 Product 4), including contact tension, fluid-film thickness, and stress-based existence calculation. Advanced bearings could be defined with a variety of predefined roller and raceway crowns, or with a measured crown.
