1.0.1 This standard is developed with a view to realizing universalization, serialization and standardization of metro gauges, facilitating standardization of vehicle specification, controlling construction engineering land scale, and ensuring safety of metro engineering construction and operation.
1.0.2 This standard is applicable to Type A and B metro vehicles with steel wheel and steel rail and standard gauges that run at a maximum speed of 80km/h in the tunnels or on the overhead line (or ground line). It includes Type A gauges, Type B1 gauges and Type B2 gauges.
1.0.3 Metro gauges shall be classified into kinematic envelope, equipment gauges and structure gauges according to functions.
1.0.4 Calculation requirements of various gauges in this standard must be followed in new or extension engineering. Kinematic envelope shall be checked in the case that vehicles and track parameters different from this standard are selected. Besides, it is required not to exceed the kinematic envelope in this standard and to meet the equipment gauges and the structure gauges specified in this standard.
1.0.5 Other vehicles running on the same metro line shall also meet the kinematic envelope specified for the line.
1.0.6 Metro gauges shall not only meet the requirements of this standard but also comply with those specified in the current relevant compulsory ones of the nation.
2 Terms and Symbols
2.1 Terms
2.1.1 Metro gauges
Gauges refer to the graphs that ensure safe operation of metro, limit section dimension of vehicle, restrict equipment installation dimension along the line, and determine effective clearance size of building structures. Gauges are classified into kinematic envelope, equipment gauges and structure gauges according to the functional requirements.
2.1.2 Normal coordinate system
The rectangular coordinate on the two-dimensional plane vertical to the center line of straight rail line. Abscissa axis (x axis) is tangential to the designed rail top plane, ordinate axis (y axis) is vertical to the rail top plane, and the origin of coordinate of this normal coordinate system is the center point of track gauge.
2.1.3 Standard vehicle and vehicle outline
A certain kind of vehicles set for determining gauges, including structural parameters, contour sizes of cross sections and contour sizes of horizontal projection, which are all the design calculation criteria of kinematic envelopes. Connecting line between the outermost points on the cross section of standard vehicle is outline of standard vehicle.
2.1.4 Kinematic envelope
The statistical track of a standard vehicle (no matter empty or heavy) running along a straight and flat rail at specified speed, including transverse and vertical dynamic deviation on each position generated by specified tolerance of vehicle and rail, abrasion loss, elastic deformation, and various limiting factors of vehicles running under normal status, e.g. vibration, and kinematic envelope is expressed by normal coordinate system.
2.1.5 Equipment gauges
The gauge of kinematic envelope added with the factors not counted in and safety clearance (including primary or secondary suspension failure state) in the normal coordinate system. Any equipment installed outside the equipment gauges [excluding the live part of equipment within the effective platform length and that of contact line (rail) equipment], including installation error and flexible deformation, shall not intrude the boundary.
2.1.6 Structure gauges
The boundary outside the equipment gauges, with equipment installation along the line taken into consideration. Any permanent fixed structures along the line, including construction error, measuring error and permanent structure deformation amount, shall not intrude the boundary.
2.1.7 Throw and quantity of throw
Throw refers to the phenomenon that coordinate points of a standard vehicle on the outline deviate from the defined reference positions when running due to tolerance, abrasion loss, elastic deformation, vehicle vibration and other reasons. Lateral throw refers to the throw in the abscissa direction; vertical (upward or downward) throw refers to the throw in the ordinate direction. Quantity of throw refers to the quantized value the above throw.
