This proposal will develop a system to provide a complete gear transmission simulation code to be used by government, industries, academia and private individuals over the Internet. Gear transmission simulation software for spur, helical, star and multiple planetary systems willbe developed and verified for various applications. The simulation code will include the effects of profile modification, tip relief, non-standard center distances, misalignment, variable lubricant properties,and tooth surface damage. The software capabilities will include large and small material deformations, transient gear tooth loading conditions and gear tooth stress analysis, transient and steady state dynamic analysis, gear mesh stiffness and damping, and condition-based gear tooth health monitoring. The objective of this proposal will be achieved by using an existing NASA funded gear analysis code (GEARDYNMULT) as the building block for the development of this software. The bearingsoftware will be disseminated via the Internet. B&C Engineering Associates, Inc. (B&CEA) and Partners in Scientific Computing (PSCICO) are currently working together to develop a virtual library' of scientificcodes which government, industry, academia and private individuals can utilize to perform research, verification and design in various areas of science and engineering. While the developed software will be executed in the BCEA workstation, only uploading and downloading capabilities are required from the user. The code will be accompanied by a user-friendly graphical user interface (GUI) with pre- and post- processor capabilities, along with an extensive help and a tutorial section. Such collaboration will provide users with state of the art software and the facilities with which to learn and use the software at substantial savings to those users.
Benefits: The generalized and integrated computer code for high speed and high load gear transmission systems will allow a onestop computational facility for analysis and design of a large variety of transmissions. The availability of the code usage over the Internet and requiring the end user to have upload and download facilities only, will create a low cost, high reliability commercialscientific source. The code should attract a large commercial base (big industry, mid-cap companies, and individual consultants) through its Internet availability, ease of use, fast learning curve, and cost per CPU unit.
