Abstract

Disclosed is a temperature controllable fluid dynamic simulating test device which comprises: a motor, a stepless speed change device, a rotary drum for fixing sample, a water storage container and a thermostat device. The thermostat is injected with see water, starting water pump when amounting to the temperature requirement; releasing the sea water into the water storage container, when the water temperature in the water storage container meeting requirement and being stable, open the motor, a relative movement between the sample and the sea water in equal temperature being generated with the drum rotation. In the dynamic simulating test, the temperature of the sea water ranges from ambient temperature to 60íµ which is adequate for researching sea water temperature impacts. The impacts on materials caused by pH value, saltiness, dissolved matter can be researched by adjusting the water medium parameter of artificial sea water.

Description

technical field [0001] The invention belongs to the technical field of material performance testing. The invention relates to a test device for testing and evaluating the damage characteristics of ship structural materials and protective coating materials under the synergistic action of seawater corrosion and seawater shear stress by adopting a dynamic simulation method of ships navigating in the ocean and controlling changes in seawater temperature. Background technique [0002] During the sea voyage of the ship, the hull structural materials or protective coating are corroded and sheared by the flowing seawater. At the same time, the temperature of the seawater also changes greatly with the change of air temperature. At present, at home and abroad, most of the dynamic seawater corrosion simulation test devices are established in port marine test stations. Considering the influence of factors such as temperature, the test cycle takes about 1 year (experiencing changes in di...
