Dynamic Analysis of the Pixie Buoy for Project Linear Chair

摘要

The PIXIE Buoy has been chosen as the initial platform to be used for acquiring airborne magnetic, electric, and electromagnetic measurements during the preliminary sea trials of the LINEAR CHAIR system in FY 80. A mooring system must be developed that will minimize buoy motion response in both shallow (100 to 200 feet) and deep (2000 to 3000 feet) water configurations. The following analytical data are illustrative of a technique to predict and evaluate the expected responses of the PIXIE Buoy under various sea conditions and mooring configurations. These equations and graphs are meant as an aid to the investigator in designing the optimum mooring configuration for the buoy with regards to allowable motion and tilt as determined by the sensitivity of the buoy-mounted instruments. Actual numerical values presented are only illustrative as they do not reflect the actual configuration of the PIXIE Buoy as it will be used In the LINEAR CHAIR tests. Once the actual numerical values for the various parameters have been established, the following technique can be used to generate more accurate values of the buoy response. (Author)
