O INTRODUCTION As space vehicles and structures become larger and more complex, the development of systems to assist humans in assemblin
21、g, op- erating, maintaining, and performing space rescue or retrieval of these vehicles and structures becomes increasingly important. With the diversity of international spacecraft, both manned and unmanned, planned to be in orbit in the not too distant future, a set of guidelines for berthing and
22、docking subsys- tems is mandatory if servicing, resupply and retrieval is to become practical on an interna- tional level. Successful interaction between these space systems, and with ground and/or space-based humans, requires standardized and effective operational interface designs, particularly wi
23、th respect to space grasp- ing/berthing/docking interface mechanisms. This document addresses the design guidelines for such mechanisms. 1.1 Purpose The purpose of this document is to provide design guidelines for mechanical berthing / docking interface between space structures, elements, and servic
24、eable or servicer vehicles. 1.2 Application This document encompasses the mechanical aspects of interfaces for space systems that require physical contact to perform space as- sembly, resupply, crew exchange, mainte- nance and retrieval functions, and related space operutions. 1.3 Intended Use This
25、guide should be used by spacecraft con- tractors, spacecraft project managers, inter- face designers and system engineers, and space operations personnel. It is recom- mended that the interface design set forth in this guide be used by all agencies, domestic and international, when specifying and de

Dock - To join the attachment mechanisms of an active spacecraft with a passive or co- operative payload or another spacecraft by actively commanding the translational and/or rotational maneuvers necessary to bring them together and latch, usually associated with im

Grapple - To close the snares on an end ef- fector, such as the cable-tension Orbiter Re- mote Manipulator Systems (RMS) end effec- tor

33、herwise provide a mainte- nance service on orbit. 3.0 GENERAL REQUIREMENTS 3.1 Standard Units of Measure Units designed to the requirements of this guideline shall incorporate the International System of units (SI) as the basic measure- ment system. These units shall be as defined in DoD-Std-1476a.
34、For measurement values not covered in DoD-Std-l476a, the document Fed-Std-376a may be used as a supplement. Linear dimensions shall be in whole millimeters. 3.2 Coordinate System An X, Y, Z three axis orthogonal coordinate system is defined for the grasping, berthing, docking interface, with the -X
35、coordinate de- noting travel in the direction of the docking or grasping engagement interface. The Y and Z axes are perpendicular to the X axis with the 2 axis vertical toward a designated up index point around the X axis. The Y axis is per- pendicular to the Z axis and is oriented lateral to the de
36、signated up index of the Z axis. 3.3 Design Considerations 1) The design and mechanical interfaces should be kept as simple as possible and de- signed for high reliability, and 2) the design should be as durable as practical within the weight and space constraints. 3.4 Interface Considerations Consi
37、derations of docking or berthing one vehicle to another consists of measuring the relative states of the vehicles, maneuvering to change the states to desired values and fi- nally, securing one vehicle to another. Errors and uncertainties complicate these steps. The sensors used to measure the relat
38、ive states have inherent uncertainties on the measured values. Thus, as maneuvers are performed to complete the rendezvous and docking/ berthing maneuvers, residual uncertainties re- sult in uncertainties in the vehicle states at contact. The interface hardware must com- pensate for the worst case u
39、ncertainties to as- sure a successful docking or berthing. Some of the interface mechanism design parameters that are influenced by the conditions of the vehicles and their mechanisms at docking or capture are illustrated in Figure 1. Other conditions which must be considered in the interface design
40、 are: latch engagement toler- ance, latch activation (latching and unlatch- ing) force limits, latch engagement over-cen- ter force limits, latch mounting structure in- tegrity requirements, impact momentum tol- erance, tip-off dynamics limits, emergency disconnect provisions for minimum impact on v
41、ehicle, thermal distortions of docking mechanism, fluid and electrical interfaces alignment, electrostatic differences at contact, sizing limitations, mass (lightest design for required strength), and reliability. 3.5 Attachment Sequence Initial Condition Capture/Centering - With the active system a
42、nd the passive system in sufficient proximity to initiate mating, one systems attachment mecha- nism shall accommodate the other sys- tems mechanism. The travel path of the active system may be guided into coinci- dence with the required path to complete mating either by physical contact or en- velo
43、pment of the smaller system by the lager. Joining - The systems attachment mech- anisms return to their nominal condition and complete a rigidized lock. UnlocWSepamtion - Above sequence is reversed and the active system shall separate with minimum tip-off dynamics. 3.6 Application of Requirements De
