A computer-implemented system is disclosed for producing a design for a rotating machine assembly. It comprises a data module (10) configured for receiving data relating to one or more components of the rotating machine assembly; a user interface module (20 configured for specifying data to be received by the data module and for receiving from a user a type of analysis to be performed on the data; and an analysis module (30) configured for analysing a performance of the rotating machine assembly according to the type of analysis selected and selected features of the data to be used. It further includes a recognition module (40) configured for identifying and selected features of the data be used for the analysis according to the type of analysis selected. It provides an approach for managing and coordinating the data in the design of driveline systems so that the most accurate and informative insight on the driveline's performance is delivered to the engineer at the earliest possible point in the design process, hence product design and optimisation can be carried out as quickly and efficiently as possible. More aspects of product performance are coordinated together and the engineering insight is greater, hence the methodology becomes a platform for making engineering decisions rather than mathematical simulation.
A computer-implemented system for producing a design for a rotating machine assembly comprising:
A system according to any preceding claim, in which data provided to the data module comprises solid geometry imported from CAD and data relating to other components including shafts, bearings, and gears, and wherein these have been positioned, a 3D mesh is created by the analysis module.
A system according to any preceding claim, in which the process of planet carrier mesh generation, connection and condensation is combined with calculation of planetary gear load sharing in the analysis module.
A system according to any preceding claim, in which the process of housing and planet carrier mesh generation, connection and condensation is combined with calculation of gear mesh misalignment, transmission error, stress and life in the analysis module.
A system according to any preceding claim, in which the process of housing and planet carrier mesh generation, connection and condensation is combined with calculation of modal frequencies and mode shapes and forced response to transmission in the analysis module.
A system according to any preceding claim, in which the analysis module performs a stress analysis of a 3D FE structure.
A system according to any preceding claim, in which the data module receives a rotating machine assembly and the recognition module identifies connections to shafts.
A system according to claim 23, in which different element types for different shafts are used in the same driveline model
A computer-implemented method of computer aided engineering for producing a design for a rotating machine assembly comprising the steps of:
A method according to any preceding claim, additionally comprising the step of determining the analytical structure for the type of analysis selected.
