Content
Model-Based Systems Engineering (MBSE) enables requirements, design, analysis, verification, and validation associated with the development of complex systems. Obtaining data for such systems is dependent on multiple stakeholders and has issues related to communication, data loss, accuracy, and traceability which results in time delays. This paper presents the development of a new process for requirement verification by connecting System Architecture Model (SAM) with multi-fidelity, multi-disciplinary analytical models. Stakeholders can explore design alternatives at a conceptual stage, validate performance, refine system models, and take better informed decisions.
The use-case of connecting system requirements to engineering analysis is implemented through ANSYS ModelCenter which integrates MBSE tool CAMEO with simulation tools Motor-CAD and Twin Builder. This automated workflow translates requirements to engineering simulations, captures output and performs validations. System Architecture Model is created in CAMEO with requirements and structure diagram. Motor-CAD is used to calculate motor performance and efficiency map. Twin Builder is used to develop an integrated system (EV) model and calculate vehicle level performance characteristics such as vehicle range, acceleration and gradeability etc. Trade studies are performed to evaluate design alternatives. Ansys ModelCenter empowers engineers and decision makers by providing early requirement verification capabilities thereby reducing re-work and enhancing efficiency in product development.
