拖曳水池是研究大型结构水动力性能的主要实验设施,为了揭示水下机械臂涡激振动响应,解决传统涡激振动装置调速形式单一、不能连续测试等问题,利用TRIZ和AHP(层次分析法)创新设计了一种适用于水下机械臂涡激振动测试装置。首先,对涡激振动测试装置进行技术成熟度预测、系统分析,确定了现有涡激振动测试装置的发展趋势、存在问题。然后,利用冲突矩阵进行技术冲突求解,获得了3种备选的创新性方案。最后,通过AHP在3种创新设计方案中确定了最佳方案,将一般解转换成特殊解,创新设计了可营造均匀流及剪切流多种流场的水下机械臂涡激振动测试装置,实现了水下机械臂单一装置下多流场涡激振动测试。

Towing pool is the main experimental facility to study the hydrodynamic performance of large structures.In order to reveal the vortex induced vibration response of underwater manipulator and solve the problems that the speed regulation form of traditional vortex induced vibration device is single and can not be tested continuously,a vortex induced vibration test device suitable for underwater manipulator is innovatively designed by using TRIZ and AHP(Analytic Hierarchy Process).Firstly,the technical maturity prediction,system analysis of the vortex induced vibration test device are carried out,and the development trend,existing problems of the existing vortex induced vibration test device are determined.Then,the conflict matrix is used to solve the technical conflict,and three alternative innovative schemes are obtained.Finally,the optimal scheme is determined in the three innovative design schemes through AHP,the general solution is transformed into a special solution,and the vortex induced vibration test device of underwater manipulator which can create multiple flow fields of parallel flow and shear flow is innovatively designed,which realizes the multiple flow field vortex induced vibration test of underwater manipulator under a single device.
