Abstract

The invention discloses a ship hydrostatic force performance experimental device which comprises a water tank and a ship body model placed in the water tank. A transverse inclination torque measuring device is arranged on the side, close to a stem, of the water tank; the ship body model comprises a ballasting system for guaranteeing that the ship body model does not incline, and a weight system for simulating loads on a ship, and the weight system comprises a stem weight, a midship weight and a stern weight which are located on the longitudinal axis face of the ship body model. An adjustable weight perpendicular to the longitudinal axis face is arranged in the middle of the ship body model, and the left side and the right side of the ship body model are both provided with at least one deck weight. According to the experimental device, the all true ship body model is erected, the hydrostatic force characteristics including buoyancy, stability, unsinkability, fastness, seaworthiness and operability in water are simulated, and operation is easy; a reinforced glass fiber plastic shell and metal upper layer equipment are adopted in the ship body model, so that the manufacturing price is low.

Description

technical field [0001] The invention relates to a ship navigation performance test device, in particular to a ship hydrostatic performance test device and an test method thereof. Background technique [0002] The hydrostatic force of a ship is a science to study the sailing performance of a ship. Only by understanding the hydrostatic characteristics of a ship can a ship be truly designed, built and operated. The hydrostatic characteristics of ships include buoyancy, stability, anti-sinkability, rapidity, seaworthiness and maneuverability. Understanding them plays a vital role in judging whether a ship has a reasonable floating state and sufficient stability. [0003] Today, there is no uniform equipment for testing the hydrostatic performance of ships, and the requirements for testing ships are relatively high, which takes a long time, costs high, and is complicated to operate. [0004] Therefore, urgently need to solve the above-mentioned problem. Contents of the inventi...
