The developer will not include self-directed tutorials with the software, but the company will provide user training directly. The trainers customize course articles and duration to meet up the needs of each organization. A one-week training session would be adequate to cover the basic modules and some advanced topics. Many highly specialized software packages require constant use to be and stay proficient. I find that RomaxDesigner does not require this level of attention. Engineers with other obligations will find this software functional also if not used on a regular basis.
For parallel and perpendicular-axis gears, modules provide interfaces to more detailed analysis software, such as for example Simpack, LDP, and AnSol. They act as a “front end” for even more-computationally intensive formulations of bending and get in touch with stress. The mixture of these software packages is particularly powerful, since it permits cumulative damage-life analysis like the nonlinear effects of gear-tooth deflection and bearing stiffness, functioning on a fully developed tooth profile. Additional modules focus on NVH and dynamic characteristics, such as gear rattle and whine, program modal evaluation, and clutch analysis. Modules are also available to automate optimization and for the sensitivity analysis of system and element 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 analyze their effects on the rest of the system. Extra modules allow design and ranking to AGMA, DIN and ISO specifications. For parallel-axis gears, additional modules permit macrogeometry definition and optimization for manufacturability as well as detailed evaluation of microgeometry for contact stress and transmission error. RomaxDesigner graphics are ideal for a number of reporting illustrations, such as system topology and component deflection.
Bearing models provide nonlinear stiffness interactions with adjacent components, which can be critical when calculating gear-support stiffness, gear-mesh misalignments and preload requirements. When calculating bearing lifestyle, the models are the effects of misalignments developed through the flexibility of any coupled elements. A bearing preload tool automates studies 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 life calculation. Advanced bearings could be defined with a variety of predefined roller and raceway crowns, or with a measured crown.
