Two vehicle chassis design tasks were solved by decomposition-based multi-disciplinary optimisation (MDO) methods, namely collaborative (CO) and analytical target cascading (ATC). A passive suspension system was optimised applying both CO ATC. Multiple parameters of the spring damper selected as variables. The discomfort, road holding, total mass spring–damper combination objective functions. A...

In a variety of tasks performed in construction sites, coordinated operations of multi-vehicles are foreshadowed to outperform the deployment of a single vehicle in terms of increased capacity and flexibility. This paper presents the application of the particle swarm optimization (PSO) algorithm in deriving drive commands, speed and turning, for the vehicles such that they are steered into and ...

The Multi-Mission Earth Entry Vehicle project is developing an integrated tool called “Multi Mission System Analysis for Planetary Entry Descent and Landing” that will provide key technology solutions including mass sizing, aerodynamics, aerothermodynamics, and thermal and structural analysis for any given sample return mission. Thermal soak analysis and temperature predictions of various compo...
