Title: Relay Control of A Morphing Tensegrity Structure with Distributed Pneumatic Actuation
Author: Guanyu Lai Univ. of Bath

Abstract: It is believed that structures and actuation systems should be tightly integrated together in the future to create lightweight dynamic machines. This requires actuators to be distributed through the structure. A tensegrity structure is a very promising candidate for this future integration due to its potentially excellent stiffness and strength-to-weight ratio, and the inherent advantage of being a multi-element structure into which actuators can be embedded. In this paper, an antagonistic multi-axis control of a tensegrity structure is achieved, using a dead band controller. The controller is studied by the describing function technique, and a condition to guarantee stability is derived. The stability condition is illustrated with simulation and experimental results, and is used as a general rule to achieve stable control of the structure.

Abstract: The pilot-control globe valve (PCGV) can use the pressure difference of a fluid itself for fluid control by a pilot valve with low driving energy consumption and quick response. In this paper, three different PCGVs are introduced with their structures and fluid dynamic characteristics. By comparing the stable valve core displacement of PCGV between the simulation and the experiment, the numerical method is validated. Then, with the three PCGVs models, the flow characteristics, the pressure difference between the upside and bottom of the valve core, between the inlet and outlet of valves, and the dynamic valve core movements are determined respectively. Furthermore, new applications of PCGVs are briefly introduced. This work gives an overall novel design introduction on PCGVs and it can be useful for someone who deals with quick response valve design at related industries.
Title: Characteristics of Cavitation in Tube

Abstract: The subsequent characteristics after cavitation bubble collapsed in a tube are investigated experimentally and emulationally. With the help of high-speed camera and COMSOL software, the interactions between primary bubble and secondary bubble in a tube are analyzed. Various behaviors of secondary cavitation are related to the primary bubble and surrounding restriction. It is found that the intensity of the secondary bubble clusters and their lifetime depend on the properties of tube including geometry and Young’s modulus. The relative position of secondary cavitation is related to the location of first bubble. Besides, collapse of large bubble produces large-scale area of secondary cavitation clusters. On the other hand, the energy distribution of secondary bubble clusters has a correlation with the Young’s modulus of tube.At last the state of two first bubbles collapse in a rigid tube simultaneously is studied, too.
