An optimization design scheme is crucial for torpedo, however, there has been no any such method recognized so far. This paper presents a method for torpedo lineshape optimization design based on the iSIGHT. In this method, the optimization strategies of simulated annealing algorithm and continuous quadratic planning method are adopted, and the fluid analysis software Fluent is integrated to calculate the fluid parameters of torpedo body lineshape. The comparison of the optimization results obtained by both the presented and the traditional methods shows that the torpedo lineshape optimization method based on the iSIGHT is satisfactory and feasible.

寻找最优设计方案是鱼雷设计的重中之重，针对目前鱼雷优化设计领域还没有一套公认的优化设计方法这一现状，提出了一套基于iSIGHT的工程设计优化方法，将这款商业软件应用于鱼雷线形优化设计中，采用了模拟退火算法+连续二次规划法的优化策略，集成流体分析软件Fluent对雷体线形的流体参数进行了计算，并与传统优化方法结果相比较，结果表明，基于iSIGHT的优化设计方法在鱼雷线形优化设计中是可行的，能够得到令设计人员满意的鱼雷线形优化方案。

Comparison of the test and simulation data verified the validity of the mathematical trajectory model, and proved that the current submarine torpedo tube could not launch the 534 mm torpedo.

115 caprine right femurs were taken and created to simulate AO/33-A3 fracture. All fracture models were fixed by the right 5 hole LISS Plate, which treated differently by using unicortical or bicortical screws in the proximal end of the LISS plate. And then withdrawal force and torsional force were given on them to make comparison.

取115根新鲜羊右侧股骨，造成股骨远端AO分型33-A3型骨折，并均采用5孔右侧股骨远端LISS钢板予以固定，在骨折近端固定螺钉单双皮质不同分布状态下，分别作拔出和扭转的生物力学对比试验研究。

The design of image fountain signal, imaging technique and data processing are three key technologies to carry out CCD torsional oscillation measurement method. By analyzing the design principle, the paper devised an image source signal alternated with black and white strip and it has a good effect. Meanwhile, the system demand of imaging link was analyzed, such as light source, lens and camera etc. In addition, the principles of both the correlation algorithm and generalized correlation time delay estimation based on adaptive technology were studied, and a comparison between them was made as well.
