Simulation Software facilitates transmission design.
Press Release Summary:
SABR provides tools for simulation, analysis, and concept design of transmission gear, shaft, and bearing systems. With 3D quasi-static simulation, program offers graphical environment to enable construction of whole transmissions, and Solver feature assesses transmission in terms of bearing life, shaft deflection, and shaft stress concentration. Shafts are modeled with spreadsheet-type input, and any number of power flows can be specified with torque and speed directions.

Ricardo Announces SABR Simulation Package to Help Optimize Strength, Weight and Cost in New Transmission Design
VAN BUREN TWP., Mich., May 15 -- To meet the needs of transmission engineers for improved levels of strength, weight and cost optimization in new product designs, Ricardo plc -- one of the world's foremost independent automotive engineering and management consulting firms -- has announced its latest innovative simulation package called SABR.
Based on technology developed and proven by Ricardo's transmission and driveline engineering teams -- whose application experience ranges across all types of vehicles from off-highway to motorsports -- SABR provides a comprehensive toolkit for the simulation, analysis and concept design of transmission gear, shaft and bearing systems.
"In keeping with our commitment to provide superior software tools, we are proud to announce our SABR simulation package," said Steve Sapsford, director of Ricardo Software. "SABR is another example of our dedication to software and applications research and development, with the goal of assisting our customers with improved product designs."
With a three-dimensional quasi-static simulation, Ricardo's SABR was specifically developed for transmission shaft and bearing system analysis, providing a user-friendly graphical environment to enable whole transmissions to be constructed rapidly and accurately. The advanced solver enables the transmission to be assessed in terms of bearing life, shaft deflection and shaft stress concentration. Key features of SABR 1.0 include:
-- Transmission Modeling - The building block construction of SABR allows modeling of virtually any transmission. Shafts are modeled with simple spreadsheet-type input to reduce build time and allow rapid assessment of conceptual shaft sizing. In addition, bearing locations and types are specified, allowing rapid selection of bearings and bearing arrangements.
-- Bearing Catalogues - A global bearing database allows for consistent development across an organization. A local bearing database stores an individual conceptual bearing design.
-- Duty Cycles - Any number of power flows can be specified with torque and speed directions, including torque reduction, at any point during the power flow.
-- Results Presentation - Shaft deflections and slopes are represented graphically and numerically. Shaft stresses, bending momentum and shear force diagrams are represented graphically and shaft stress contours are shown. In addition, bending momentum and shear force diagrams for each shaft and load case give the designer essential information for shaft design. Customers can also identify gear misalignments and compare against defined targets for rapid problem identification.
Ricardo Software offers a portfolio of advanced simulation software for engine and powertrain design. Anchored by WAVE, a market-leading engine performance and one-dimensional gas dynamics code, Ricardo's software suite also includes VECTIS, ENGDYN, VALDYN, PISDYN and RINGPAK. When integrated with industry-standard analysis, computer-aided design and finite element packages, Ricardo Software facilitates the robust "analysis-led design process" practiced by Ricardo and leading original equipment manufacturers around the world.
