摘要

This work develops a flexible and modular Discrete Element Method paradigm for rapid quadcopter drone analysis and simulation. The main components are (1) modular assembly of structural components and (2) flexible feature addition and deletion and dynamic drone flight performance evaluation. As a model problem, we illustrate the concepts above for the design and analysis of a quadcopter and its subsequent dynamic flight performance in an extreme environment. The outline of the work is (a) modular generation of voxel-based discrete elements, (b) preflight stress testing using voxel-based discrete elements, (c) structural materials for drones, (d) voxel-based discrete elements for dynamic drone flight evaluation and (e) extensions to fully finite-deformation structural flight dynamics. Numerical examples are provided to illustrate the overall approach and its straightforward implementation.
