In recent years, the trimaran as a novel ship has been greatly developed. The subsequent large vertical motion needs to be studied and resolved. In this article, an experimental study for a trimaran vertical stabilization control is carried out. Three modes including the bare trimaran (the trimaran without appendages, the trimaran with fixed appendages, and the trimaran with controlled appendages) are performed through model tests in a towing tank. The model tests are performed in regular waves. The range of wave period is 2.0–4.0 s, and the speed of the carriage is 2.93 and 6.51 m/s. The results of the three modes show the fixed appendages and the actively controlled appendages are all effective for the vertical motion reduction of the trimaran. Moreover, the controlled appendages are more effective for the vertical stability performance of the trimaran.

基于协同控制附件的三体船垂向运动抑制研究

近年来，三体船作为一种新型船舶得到了很大的发展。随后的大垂直运动需要研究和解决。在本文中，进行了三体船垂直稳定控制的实验研究。在拖曳水池中通过模型试验进行了三种模式，包括裸三体船（无附肢三体船、固定附肢三体船和控制附肢三体船）。模型试验在规则波中进行。波周期范围为2.0~4.0 s，小车速度为2.93和6.51 m/s。三种模式的结果表明固定附肢和主动控制附肢对三体船的垂直运动减少都是有效的。而且，
