The most important task for 3D assembly tolerance analysis is to check how the tolerances affect the quality or functionality of a product when the parts are assembled together. This paper presents the way 3D statistical tolerance analyses are implemented by integrating the unified Jacobian-Torsor model and Monte Carlo simulation techniques. To perform 3D statistical tolerance analysis, a unified...
X-ray pulsar-based navigation method is a promising autonomous navigation method. The research has been done for nearly 30 years. Several key techniques about this method are the research hotspots now. One of the key techniques is estimation of the time of arrival (TOA) in pulsar's signal processing. The precision of the TOA would affect the precision of X-ray pulsar-based navigation. Using Monte...
In order to evaluate combat effectiveness of missile weapon system, especially to provide guidance for structural plan design and fuse-warhead coordination design, this paper hereby studies issues about terminal efficiency of three-dimensional fragment type air-to-air missile. Terminal efficiency computation framework of projectile is established, and detailed modeling is conducted to single-shot...
