ship motion การใช้

• Ship motions have physiological effects on ship passengers and crew.
• Ship motion and / or abnormal floating position may decrease the ability to move.
• His role was to advise the company on aspects of ship motion and ship design.
• :If you're looking to keep the metaphor consistent, see Ship motions.
• Later plotters allowed for the simultaneous plotting of position and ship motion information onto the paper record.
• The RAO's transfer function is only defined when the ship motions can be assumed to be equation of motion:
• There is typically wind ( natural or ship motion generated ) over the flight deck, giving the aircraft additional lift.
• It is common to only consider the absolute value of the RAO if the phase between the excitation and the ship motions are irrelevant.
• Ship motions are important for determining dynamic loading on the crew, passengers, ship system components, secured cargo, and structural elements.
• The magnitudes and accelerations of ship motions, ( particularly heave, roll and pitch ) have adverse effects on passengers and shipboard personnel.
• Ship motions are considered when determining the principal dimensions of the ship and in developing the general arrangements of the ship's internal spaces.
• Pad 25B was initially built with an underground launch mechanism known as a ship motion simulator to simulate the roll and pitch of a submarine.
• It has also been shown that most people acclimate to ship motions within a period of about four days, but some never acclimate at all.
• For example, in most vessels the far forward parts of the ship experience the worst ship motions and are commonly unacceptable for berthing passengers or crew.
• This new method of propulsion was an improvement over the paddlewheel as it was not so affected by either ship motions or changes in draft as the vessel burned coal.
• Aquaveo worked with the Office of Naval Research, the Carderock Division of the Naval Surface Warfare Center, and several universities and companies to create the Environmental and Ship Motion Forecasting system.
• Over time, the Dreyer system added more and more calculators, solving for the effects of wind, corrections between apparent and real wind speed and direction based on the ships motion, and similar calculations.
• Stabilizer control needs to consider numerous variables that change quickly : wind, waves, ship motion, draft, etc . Fin stabilizers are vastly more efficient at higher velocities and lose effectiveness when the ship is under a minimum speed.
• Ships today still use the process of adaptation and variation that has been used for hundreds of years; however computational fluid dynamics, ship model testing and a better overall understanding of fluid and ship motions has allowed much more analytical design.
• In exceptional cases where ship motions pose a threat to crew, structure or machinery, or when ship motions interfere with the ability of the ship to accomplish its mission, then the design must be modified so that ship motions are reduced.
