Description

Real-time active adjusting method for length of connecting rod and active anti-side-rolling torsion rod system
Technical Field
The invention belongs to the rail transit industry, and particularly relates to a real-time active adjusting method for the length of a connecting rod and an active anti-side-rolling torsion rod system.
Background
When the train turns at a high speed, objects and passengers in the train are influenced by centrifugal motion, the objects and the luggage on the train can slide sideways, the passengers on seats can be pressed aside, and standing passengers are more likely to lose balance and fall down, so that the train turning needs to reduce the speed of the train, thereby limiting the running speed of the train and limiting the line capacity. The swing train can improve the turning speed of the train, thereby improving the running speed of the train.
According to different inclination modes of the vehicle body, the vehicle can be divided into a natural pendulum type and a forced pendulum type. The natural pendulum is also called passive pendulum. The train body is supported by the roller device and the high-level air spring, and when the train passes through a curve, centrifugal force is generated, so that the train body rotates around the swing center of the train body and naturally inclines to the inner side of the curve without external power. The inclination angle of the passive pendulum type train body can reach 3-5 degrees, the angle of the passive pendulum with control can reach 3-6 degrees, and the curve running speed of the conventional train can be improved by 10-20 percent.
The forced pendulum type is also called an active pendulum. The curve detection device, the vehicle-mounted computer control device and the tilting transmission device are used for tilting, and the tilting angle can reach 10 degrees at most. The active pendulum type train body can improve the curve running speed of a conventional train by 30 to 35 percent. But the maximum angle is 2 degrees by adopting the forced swinging realized by changing the mode that the air spring of the secondary suspension of the bogie has different inflation heights. The speed-up range is mostly within 10 percent, but the cost is lower.
At the present stage, the transport capacity of partial trunk railways and urban underground railways in China tends to be saturated, and the train running speed becomes a key influence factor for restricting the transport capacity of the lines. On the basis of not changing the existing line structure, the pendulum train is developed to become an effective way for improving the curve passing speed of the train. The tilting mechanism of the pendulum train comprises a four-pendulum rod type, a rolling guide rail type, a side rolling resistance torsion rod type and an air spring type. The anti-rolling torsion bar type has the advantages of simple structure, low modification difficulty, low manufacturing cost and easiness in maintenance, and becomes a key direction for future development.
The traditional anti-side-rolling torsion bar device is composed of a torsion bar assembly, a connecting rod assembly and a supporting seat assembly, wherein the length of the connecting rod assembly cannot be adjusted in the running process of a vehicle body, and a torsion bar shaft passively generates torsional deformation when the vehicle body rolls on the side, so that anti-side-rolling reaction moment is provided for the vehicle body. The active anti-rolling torsion bar device can self-adaptively adjust the length of the connecting rod according to the line condition in the running process of a train, further enable the torsion bar shaft to be twisted and deformed, and actively provide anti-rolling moment for a train body, thereby achieving the purpose of adjusting the side rolling angle of the train body. Therefore, how to design the anti-rolling torsion bar device with the adjustable connecting rod length becomes the key for actively adjusting the side rolling angle of the vehicle body.

Detailed Description
The invention is further described by the following specific embodiments in conjunction with the attached drawings:
the existing torsion bar is shown in fig. 1: the method comprises the following steps: the automobile body tilting device comprises a connecting rod 1, a torsion rod 2 and a supporting seat 3, wherein the torsion rod 2 is fixed on a bogie through the supporting seat 3, two rotating arms of the torsion rod 2 are hinged to two sides of an automobile body through the two connecting rods 1 respectively, and when the automobile body tilts, the connecting rods 1 on two sides of the automobile body drive the two rotating arms of the torsion rod 2 to rotate in opposite directions respectively, so that the torsion rod 2 generates torsional deformation, and side rolling resisting moment opposite to the tilting of the automobile body is generated, so that gravity moment generated after the automobile body tilts is balanced, and driving safety.
Since the centrifugal force of train turning tends to cause the train body to roll, the anti-roll moment of the torsion bar 2 is not sufficient to balance the overturning moment generated by the train centrifugal force when the speed is high, so that the anti-roll moment of the torsion bar 2 needs to be increased. The anti-roll moment can be increased by adopting the real-time active adjusting mode of the connecting rod length.
As shown in fig. 2: the real-time active adjusting method of the length of the connecting rod comprises the step of dividing the connecting rod into a first connecting rod part A and a second connecting rod part B, wherein the first connecting rod part A and the second connecting rod part B are movably connected through an active adjusting device C, and the active adjusting device C can actively adjust the length L of the connecting rod in real time according to a control instruction. And then the torsion bar shaft is twisted and deformed, and the anti-rolling moment is actively provided for the train body, so that the side rolling angle of the train body adapts to the line condition, and the running speed of the train is improved.

When a train enters a curve, a driver sends a control instruction for changing the length L of the connecting rod, so that the connecting rod 1 positioned on the outer side of the curve is extended, and the connecting rod 1 positioned on the inner side of the curve is shortened, therefore, the torsion bar 2 generates larger anti-rolling moment to balance the rolling moment generated by centrifugal force, so that the train can safely pass through the curve at a higher speed, and the running speed of the train is improved.
