Design Composites Pressure Vessels with Ansys and CADWIND
Composite pressure vessels are a common solution for storing gases and liquids at high pressures. Their lightweight design is beneficial to a wide range of applications in the automotive, aerospace and mobility industries, among other.
Pressure vessels are typically manufactured with a filament winding process. Composite filaments or tapes are wound at different angles around a rotating liner. The lay-up design of the pressure vessel is dictated in many parts by the process. On certain geometric features, like vessel domes, the composite filaments overlap in some regions more than others and their angles of orientation and mechanical properties vary. CADWIND simulates the filament winding process and generates machine codes for an automated laying. Then, ACP finite element models (FEMs) can be used to analyze the structural response to internal pressures, impacts and other loading conditions, taking into account the complexities of the layup.
