Urban rail transit line longitudinal section design of the main technical elements are

The main technical parameters of urban rail transit vehicles are as follows:

(1) Vehicle deadweight, load and volume.

Vehicle construction speed. Vehicle construction speed is the maximum speed of the vehicle allowed by the safety and structural strength. (3) Axle weight. Axle weight is a vehicle in a range of operating speeds within an axle allowed to bear the maximum total mass, including the weight of the wheels themselves.

(4) through the minimum curve radius. The minimum radius through the curve is related to the type and design of the bogie.

(5) Maximum starting acceleration. Maximum starting acceleration includes average starting acceleration and maximum braking deceleration. (6) Braking form. Braking forms include friction braking, regenerative braking, resistance braking and magnetic rail braking and other forms.

(7) axle configuration or number of axles. For example, four-axle moving car generally set up two power bogies:

Six-axle single-winch light rail vehicle - generally two ends of the power bogies, the middle of the non-power bogies.

(8) supply voltage, maximum network current, traction motor power.

Passenger capacity). (9) Number of seats and number of standing persons or passenger capacity per square meter of floor area (seat capacity, fixed capacity, overcrowding).

Urban rail transit has a strong transportation capacity. Urban rail transit has a strong transportation capacity due to the characteristics of high-density operation, short time interval between trains, high speed, and a large number of cars in the Liu car group.

The peak hourly transportation capacity can reach a maximum of 60,000 ~ 80,000 (suburban rail), the subway for 40,000 ~ 60,000 light rail for 10,000 ~ 40,000, tram can reach 10,000, the transportation capacity of the urban rail transit is far from the public **** car.
