Purpose In the future, large space truss structures will be likely to require on-orbit assembly. One of several proposed methods includes cooperative assembly performed by pressure-suited astronauts during extravehicular activity (EVA) and robots. An intelligent planning method was presented generate optimal tasks. Design/methodology/approach Firstly, inherent hierarchical nature allows sequences considered from strut level structural volume element (SVE) level. Then, a serial strategy in...
This article researches the improvement of dynamics stability ducted fan unmanned aerial vehicles by optimizing its mechanical–structure parameters. The instability phenomenon takes place frequently due to complicated airflow in near-earth space, which easily leads problems, such as out control, shaking, and loss accuracy command tracking. equations mirror characteristics, are primarily influenced parameters whole system. Based on this, optimization has a significant improve Therefore, this...
To increase dynamic stability of the quadrotor unmanned aerial vehicles in varying mechanical structure. The qualitative analysis is considered main methods for analyzing stability, while index structural and are still hard to establish. Therefore, process during rolling or pitching selected investigating present papers, method Lyapunov exponent adopted establishing quantification relationship between parameters its guiding design vehicle's structure optimization control by using...
With the increase of train speed, aerodynamic drag as a part running resistance becomes increasingly important for train. In order to reduce drag, configuration optimization is required heads, especially high-speed trains. A simulation based heads developed in this paper on basis computational fluid dynamics theory. Both manual and Sculptor-software-integration curve-driven arbitrary deformation are used compared. The results state that optimal head can be obtained by combining three...
