Abstract
The take-off stability of lunar detector is an important performance index of an ascender′s taking off from the moon′s surface.By choosing some main influence factors of take-off stability, the take-off dynamic approximation model of ascender was established combining with an optimal latin hypercube experimental design method and the RBF neural network,and the sensitivity of the factors for the angular displacement and velocity was quantitatively analyzed. Based on the stability criterion that the angular displacement and angular velocity of ascenders was 5° and 5 (°)/s respectively, the boundary values of a single influence factor were given.A program for multiple factors boundary analysis of the ascender take-off stability was compiled.The boundary expression of the ascender take-off stability is founded by the way of three-dimensional space, and the take-off stability boundaries were determined with a sample.关键词
