【摘要】 本文介绍了上海交通大学研制的垂直面平面运动机构。平面运动机构是一种使被试验船模产生正弦振荡,以测量其水动力系数的试验装置。它用于潜艇、潜水器、鱼雷、导弹等水下运动体的水动力性能研究。机构由振荡机构、驱动电控系统、测力与数据处理系统等组成。在研制中采用了一些新技术,与国外同类机构相比,它具有结构紧凑、测试精度高、获取数据多等优点。更多还原

【Abstract】 This paper introduces a planar motion mechanism(PMM) in vertical plane of SJTU. The PMM is a device that imparts a sinusoidal motion to a vehicle model that is towed along a towing tank to measure its various hydrodynamic coefficients.ft can be used for researching hydrodynamic performance of underwater vehicles or other objects,such as submarine,submersible, torpedo,guided missile and rocket etc. The PMM consists of oscillation mechanism, driving and controlling system,electric measuring and data processing system. Since some new techniques are adopted, the PMM has the following advantages,compared with same kind of foreign ones:structurally compact,reliable for data acquisition, convenient to operate,and of high precision.更多还原
