Abstract: The main body of the article briefed the total frame, composing, application case of multidisciplinary optimization technology for weapon equipment system,and introduced 5 kinds of multidisciplinary optimization method detailedly. It took a certain equipment's virtual prototyping optimization design requirement in the engineering develop phase as the background, and advanced the way of multidisciplinary virtual prototyping optimization based on local subsystem analysis viably, shortened form LSA-IDF. Then through an actual case application, the article constructed the weapon equipment system's virtual prototyping optimization design flow, actualized intelligent optimization design based on virtual prototyping. Finally it sums up the applying effect, and advances the project's future direction for the latter research work.

Key words: virtual prototyping, multidisciplinary optimization method, LSA-IDF, optimization design flow
