The developer does not include self-directed tutorials with the program, but the company will provide user training directly. The trainers customize program content material and duration to meet up the needs of each organization. A one-week training session would be enough to cover the essential modules and a few advanced topics. Many extremely specialized software programs require constant use to be and stay proficient. I discover that RomaxDesigner will not require this degree 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 detailed analysis software, such as Simpack, LDP, and AnSol. They become a “front side end” for also more-computationally intensive formulations of bending and contact stress. The combination of these software programs is particularly powerful, since it permits cumulative damage-existence analysis including the nonlinear ramifications of gear-tooth deflection and bearing stiffness, functioning on a fully developed tooth profile. Extra modules concentrate on NVH and dynamic characteristics, such as equipment rattle and whine, system modal analysis, 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 models gears with enough detail to analyze their effects on all of those other system. Extra modules allow design and ranking to AGMA, DIN and ISO standards. For parallel-axis gears, extra modules permit macrogeometry definition and optimization for manufacturability as well as detailed analysis of microgeometry for get in touch with stress and transmission error. RomaxDesigner graphics are ideal for a number of reporting illustrations, such as for example system topology and element deflection.

Bearing models provide nonlinear stiffness interactions with adjacent components, which may be critical when calculating gear-support stiffness, gear-mesh misalignments and preload requirements. When calculating bearing life, the models are the effects of misalignments developed through the versatility of any coupled components. A bearing preload tool automates studies of bearing life as a function of preload. These features have already been proposed for a future release.
Advanced bearing-analysis modules offer detailed analyses (ISO 281 Product 4), including contact stress, fluid-film thickness, and stress-based life calculation. Advanced bearings could be defined with an assortment of predefined roller and raceway crowns, or with a measured crown.
