A dynamic analysis model of the novel lander is created, and all possible landing conditions at touchdown are considered. Through analyzing the landing process of free-fall landing mode, some shortcomings are found. To improve the landing stability of the novel lander, low-speed landing mode is proposed, namely, the main engine and attitude control engines are switched off soon after the lander is...
A novel approach to solving the robust topology optimization problem under loading uncertainty was developed. According to the superposition principle of linear structure, computational method for the excepted value and standard deviation of the compliance by Monte Carlo sampling is adopted. In order to avoid the computation of the sensitivity of the objective and improve computational efficiency,...
