摘　　要：拖曳水池试验是研究船舶性能的基本方法,为满足船舶试验的需要,设计了一种适用于试验领域拖曳水池的拖车结构,简述了拖曳水池拖车的基本组成,建立了基于参数设计的完整拖车三维实体模型,并对拖车抗倾覆稳定性进行校核计算,采用有限元软件建立简化后3种强度和刚度提升方案的拖车模型,采用有限元分析方法分别对其进行强度与刚度分析计算,通过对比不同方案的计算结果,得到相对最优方案的模型参数。经分析计算可知,优化后的模型强度和刚度均能够满足实际需求。The towing tank test is the basic method to study the performance of the ship. To meet needs of a ship test, a trailer structure suitable for large towing tanks is designed. The basic composition of the trailer structure is briefly described, and a complete three-dimensional entity of the trailer based on the parameter design is established. The model and its anti-overturning stability are checked and calculated. The finite element software is used to establish a simplified trailer model of three strength and stiffness improvement schemes, and the finite element method is used to analyze the strength and stiffness respectively. The analysis results of different schemes obtain the model parameters of the optimal scheme and provide corresponding theoretical basis for its actual production.
