机械效率

A new bionics propulsion equipment—fishlike flexible tail fin propulsion equipment is brought forward,because there are some problems in present thrusters,such as big noise,low propulsion efficiency in shallow water and evident wake.

本文针对现有船用螺旋桨、泵喷等常规推进器存在噪音大、浅水中船舶推进效率不高以及尾迹明显等缺点，提出一种新型仿生推进装置—仿鱼尾柔性尾鳍推进装置，并据此展开了对单翼板柔性尾鳍和双翼板柔性尾鳍模型的计算和实验研究，本文工作属于鱼类生物流体力学、机械学、材料学和控制技术等多学科交叉的一个新兴研究领域。

It is specially used for lift on/off the stone slab container and it can also be used as a normal crane. It is widely available for the factory, dock, goods yard, forestry center, building materials industry, warehouse, logistics and so on. It is a handling machinery of wide application and high efficiency.
