Design Criteria and Considerations

    32、Unless otherwise specified herein, the general requirements of ISO4413 as supplemented by NFPA T2.24.1 shall be used for guidance. ISO 4413 provides general rules relatingto hydraulic systems for machinery in industrial manufacturing processes that are generally applicable to allsystems.For deep oce

    33、an applications, the “Handbook of Hydraulic Systems for Deep Ocean Applications” providesguidance on design practices and component selection.4.1 FunctionThe function of a hydraulic system on a marine vehicle is to provide power for the operation ofequipment. Examples of applications operated by hyd

    34、raulic fluid power are rudders, trim control surfaces, largevalves, cranes, winches, hatch operators, elevators, propeller pitch control, and retractable masts. Hydraulicsystems provide for the generation of fluid power, conducting the fluid power to and from the application, andthe appropriate cont

    35、rol of the fluid power in operating the application.4.2 System ArrangementThe designer must comply with the applicable government and classification bodysrules and regulations in designing the vessel. In regard to hydraulic systems, the rules are usually general innature although specific rules may

    36、apply for systems such as steering. Requirements of the USCG may befound in Title 46 of the Code of Federal Regulations. The following parts are particularly applicable: Part 56 -Piping Systems and Appurtenances; Part 57 - Welding and Brazing; Part 58 - Main and Auxiliary Machineryand Related System

    37、s. Some requirement documents of the major classification bodies are listed in 2.6. Unlessspecific specifications are provided for the design of the hydraulic system, the guidance herein should befollowed in addition to the requirements of government regulatory agencies and the applicable classifica

    38、tionbody.The primary method of assuring reliable operation of critical components is through redundancy. The degree ofredundancy in fluid power supplies should be part of the vessel specifications. In the absence of specifications,applications critical to the safe operation of the vessel, such as st

    39、eering gear, and/or personnel safety, such asdamage control valves, should have, at a minimum, two separate power supply sources (i.e., pump, reservoir,and piping loop) and controls for the application. Should one source fail, then the other source shall provide thenecessary fluid power for the safe

    40、 operation of the application. Operation at a reduced rate in this emergencycondition may be acceptable if the safety of the vessel or personnel is not compromised. These fluid powersupply sources shall have separate electrical/mechanical power supplies. Where practical, a manual operationmode shoul

    41、d be provided for improved safety and reliability.For other applications not critical to the safe operation of the vessel, the failure mode of each application shallbe determined and the application controls designed to provide the appropriate failure mode. Examples offailure modes are “fail as is,”

    42、 “fail close,” and “fail operational.”Typically, marine components, such as winches, elevators, and capstans have dedicated power plants.However, weight and volume are critical aspects of hydraulic system design on marine vehicles. Dueconsideration should be given to the use of a central hydraulic s

    43、ystem to minimize the weight and volume ofpower plants where a large number of components are relatively close to one another. However, if critical andnon-critical applications are served by the same central hydraulic power plant, provision must be made toensure the operation of the critical compone

    44、nts is not compromised by operation of or casualty to non-criticalequipment.Stored energy should be considered to minimize the number of pumps and to reduce pump cycling.Reliability and safety of the fluid power supplies can be improved through the use of relief valves, reservoirlevel monitors, and

    45、filtration.Critical systems should have sufficient redundancy and isolation valves so that operation can continue after acomponent failure or system leak. On military ships, additional system isolation and replenishment featuresmay be required for survivability. On unmanned vehicles, redundancy may

    46、be reduced._ SAE J1775 Reaffirmed MAY2013 Page 4 of 164.2.1 HYDRAULIC POWER PLANT PACKAGEThe hydraulic system power plant should be designed, where possible,as a package unit capable of being readily removed from the vehicle for repair and test.4.3 Pressure LevelSystem pressure level shall be select

    47、ed on the basis of minimum equipment weight,maximum reliability and least life cycle cost. Higher pressures tend to minimize weight but the number ofcomponents rated above 21 MPa (3000 psi) is limited and development costs may be significantly greater forhigher pressure systems. For impact of higher

    48、 pressure on acoustic characteristics of hydraulic systems, seeSAE J1782. For intermittent duty subsystems, such as engine start subsystems, high pressures, up to 35 MPa(5000 psi), are often used to minimize weight. Variable displacement pressure compensated pumps are oftenused for pressure regulation of central hydraulic systems where the maximum operating pressure of th
