A Study On Maritime Search And Rescue Dummy And Their Drift Model

With the developing of national economy,the number of staff engag in working at sea increas rapidly,at the same time,maritime accidents have beening occurred all the time,and the number of death in victims is increasing. In that case,this paper,starting from trying to make rescue dummy,for the purpose of setting up search and rescue dummy drift model,to study supply data reference and theoretical basis for the rescue organization.,so,the rate of our maritime rescue efficiency will be improved.First of all,this paper starting from the ergonomics point of view,using the method of multiple linear analysis,to study the various parts of China's human dimensions,according to the algorithm body size measurements,to get the parameter of chinese 50-percentile body.;and then,following the studying on car collision dummy,medical dummy and aeronautical dummy,fix on the performance index and related parameters of rescue dummy;following the propose of the paper,design the function,parameter, structural of the rescue dummy,finishing the study of production of materials,electronic equipment,sensor and so on,by studying the dummy body bracketjoint connection and skin material,to design the dummy total structure.According to the research,produce the rescue dummy by watertighting, assemblying,and weighting.And then,this paper on the basis of analyzing oil spill drift model,out of control ship drift model and buoy drift model,by thinking over the own factors of dummy,through the import of the flow field,taking into account the role of wind,using the method of Lagrangian Tracking method,seting up search and rescue dummy drift model;using the methods of MATLAB and VB integration,developing Man-machine visual interfaceobject-oriented,carry out the motion simulation of the rescue dummy,suppply the study method for improving the search and rescue system function.Finally,check up the performance of rescue dummy by testing its functionality, capacity materials,sensors and electronic systems performance;based on the drift trajectory, movement status,compare the rescue dummy with real person for similarity;check up the feasibility of rescue dummy drift model by testing at sea,collect the drift tracking and drift data for analyzing them after the test at sea,so that, the drift model function.will be improved.The result of this paper study provides an important reference for further improving the search and rescue decision-making,and promotes the dummy developing in china's search and rescue domain;the paper's study make a certain role in improving the national search and rescue strength.
