4 Conditions for use
4.1 Environmental conditions
4.1.1 Normal working altitude does not exceed 1200m.
4.1.2 The ambient temperature is between -25°C and 40°C.
4.1.3 The average maximum relative humidity of the wettest month is not more
than 90% (the average minimum temperature of the month is 25°C).
4.1.4 The vehicle shall be able to withstand the attack of wind, sand, rain, and
snow and the action of the cleaning agent when the vehicle is washed.
4.1.5 Because there are differences in climatic conditions due to the different
regions in which cities are located, user and manufacturer can additionally
specify the environmental conditions for use in the contract.
4.2 Line conditions
4.2.1 The track gauge is 1435mm.
4.2.2 The minimum plane curve radius shall meet the relevant regulations of
GB 50157.
4.2.3 The minimum vertical curve radius: 2000m.
4.2.4 Maximum slope: if there are no special regulations, the maximum slope
of the main line shall not be greater than 30‰. 35‰ can be used in difficult
areas. The maximum slope of tie line and access line shall not be greater than
6 Basic requirements and general provisions
6.1 The vehicle shall comply with the regulations of the relevant subway vehicle
boundary.
6.2 The various equipment of the vehicle shall be manufactured in accordance
with the drawings and technical documents approved by the prescribed
procedures and comply with the provisions of relevant standards.
6.3 The wheel diameter is . The difference between the diameters of
the two coaxial wheels of the new vehicle does not exceed 1mm. The wheel
diameter difference of the same motor vehicle bogie does not exceed 2mm.
6.4 Wheelset inner distance is 1353mm ± 2mm.
6.5 The weight of the vehicle in the servicing state shall not be 3% greater than
the value specified in the contract.
6.6 The difference between the measured axle load on each dynamic axle of
the same motor vehicle and the actual average axle load of each dynamic axle
of the vehicle shall not exceed 2% of the actual average axle load.
6.7 The difference between the actual wheel weight of each wheel and the
average wheel weight of the axle shall not exceed ±4% of the average wheel
weight of the axle.
6.8 The height of the floor of the passenger compartment of the vehicle from
the track surface shall be coordinated with the station platform. The height
adjustment device for empty and heavy vehicles shall be able to effectively keep
the height of the vehicle floor surface from being significantly changed due to
changes in passenger capacity. The floor height shall not be lower than the
platform surface under any use.
6.9 The train shall be able to safely pass the minimum radius curve section at
the specified speed and carry out normal train pick-up and hang-up operations
on the specified small radius curve.
6.10 The traction-speed characteristics and braking force-speed characteristics
of the train shall meet the requirements of the design documents agreed
between the user and the manufacturer.
6.11 The maximum operating speed of the vehicle is not less than 80km/h.
6.12 In the case of occupancy, the wheels are in a semi-wear state on a flat and
dry track. At rated supply voltage, if there is no special requirement, the average
6.21 Parts of the same model shall have good interchangeability.
6.22 The structural materials and parts of the vehicle shall be made of high
flame retardant or flame-retardant materials. The flame retardancy of the
material, the harmful gas volatilized when the material is burned and thermally
decomposed, and the smoke density index shall meet the relevant safety and
fire protection standards. Otherwise, it shall be subjected to flame-retardant
treatment or sealed with flame-retardant and non-combustible materials. The
cables used on the vehicle shall meet the requirements of TB/T 1484.1.
6.23 The surface treatment and protective coating requirements of the vehicle
before painting shall meet the requirements of TB/T 289.3 and TB/T 2879.5.
6.24 When the vehicle needs to be transported by rail, it shall be able to meet
the requirements of unpowered return.
