Computerized analysis and design of vehicle multi-body systems /
… modelling analysis and design of vehicle systems for ride and handling studies. Characteristics of vehicle multi-body models are identified and formalisms are developed for automatic computerized equation generation and solution. These are implemented using interactive graphics and applied …

On the dynamics of rigid multi-body systems in orbit
… spacecraft attitude control system. For multi-body space systems, the mechanical couplings have significant effects on the attitude dynamics. These effects, added to the high performance requirements and the number of strict constraints that, in general, space systems have to satisfy, …

Aspects of computational contact dynamics
… computational framework for dealing with dynamic multi-body frictional contact problems. It is in fact a detailed account of an instance of the Contact Dynamics method by Moreau and Jean. Hence the title. Multi-body systems with contact constraints are common. Some of them, such as machines or …

Stability optimization of open-loop controlled walking robots
… control is applicable to a much wider range of systems than was conceived before. An open-loop stable control strategy does not use any feedback nor does it take any active measures to respond to perturbations but entirely relies on the mechanical system's natural kinematics and dynamics to …

Optimal Design and Control of Multibody Systems with Friction
In practical multibody systems, various factors such as friction, joint clearances, and external events play a significant role and can greatly influence the optimal design of the system and its controller. This research focuses on the use of gradient-based optimization methods for multibody …

Dynamics of a Small Autonomous Underwater Vehicle That Tows a Large Payload
This thesis presents the derivation of the dynamic model of an autonomous underwater vehicle that tows a large payload. Our analysis is motivated by the fact that the payload is so large that it cannot be modeled by simply appending its dynamics to the dynamics of the autonomous underwater vehicle. …

Inverse design of self-assembling colloids via landscape engineering
… are applicable to a wide class of self-assembly systems, both simulated and experimental, enabling a new frontier in the computer-aided design of self-assembling materials. The first portion of this dissertation focuses on the development of the many-body diffusion map and its application to the …

Coupled orbit-attitude mission design in the circular restricted three-body problem
<p>Trajectory design increasingly leverages multi-body dynamical structures that are based on an understanding of various types of orbits in the Circular Restricted Three-Body Problem (CR3BP). Given the more complex dynamical environment, mission applications may also benefit from deeper insight …

Algebraic level sets for CAD/CAE integration and moving boundary problems
… and analysis applications outside the CAD systems. Boolean operations between interacting B-rep CAD models as well as analysis of such multi-body systems are fundamental operations on B-rep geometries in CAD/CAE applications. However, the boundary representation of B-rep solids is, in …
