摘要： When simulation equipment receives a request relating to a drivetrain, the request containing identification information identifying one or more components of the drivetrain, and possibly one or more operation conditions, the simulation equipment retrieves, based on the identification information, component information on one or more components of the drivetrain, the component information indicating for each component a component type. The simulation equipment also retrieves, based on one or more component types in the component information and received one or more operation conditions, if any received, one or more values. Then the simulation equipment calculates a simulation result for the drivetrain and/or for one or more of components the drivetrain comprises using at least the retrieved one or more values as input for the simulation; and outputs the simulation result.
