In this paper, the problem of adding damping to a vibrating string is considered. Instead of using feedback control or frequency domain techniques, a wave-analysis approach proposed by von-Flotow for beams and trusses is used. This technique is based upon the premise that resonances are caused by waves reflecting off of discontinuities. By eliminating the reflections, the resonances will dissap...

Assuming independence between failure modes makes system reliability calculation simple but it adds approximation error. Interestingly, error due to ignoring dependence can be negligible for a highly reliable system. This paper investigates the reasons and the factors affecting the error. Error in system probability of failure (PF) is small for high reliability when tail-dependence is not very ...

On-orbit assembly is an enabling technology for many space applications. However, current methods of human assisted assembly are high in cost and risk to the crew, motivating a desire to automate the on-orbit assembly process using robotic technology. Construction of large space structures will likely involve the manipulation of flexible elements such as trusses or solar panels, and automation ...

Trusses are among the basic components of large-span bridges and large-space structures. A method is proposed to conduct a comprehensive deformation analysis truss in terms rigid body displacements tension compression based on complete mathematical orthogonality mechanical equilibrium. The correctness verified by comparison with traditional strain analysis. Furthermore, relative decomposition m...
