After the installation of the two rail wheel supporting frame assemblies 6 is finished, the synchronous belt 2 is installed again, and the two rail wheel supporting frame assemblies are connected together in a rolling way.
Referring to fig. 9 and 10, the long and short driving axle assemblies have the same structure and are installed reversely, and each long and short driving axle assembly consists of a railway vehicle test wheel set assembly 16 and a motor and gear box assembly 17, and the difference between the long and short driving axle assemblies is that the railway vehicle test wheel set assemblies 16 have different lengths. The short-track vehicle test wheel set assembly, the motor and the gear box assembly 17, and the motor and the gear box assembly 17 and the long-track vehicle test wheel set assembly are connected through shafts, so that one of the two assemblies can rotate to drive the other to rotate.
Referring to fig. 10, 12, 13 and 14, the short driving axle assembly mainly comprises a motor and gear box assembly 17, a speed reducer shaft 19, a vibrating rail wheel 20, a vibrating rail wheel bearing seat 21 and a synchronous pulley 22; the motor and gear box assembly 17 is mainly composed of a driving motor 23, a motor elastic hinge support 24, a motor elastic hinge 25, a motor ventilation pipe joint 26, a motor elastic support plate 27 and a speed reducer assembly 28.

The speed reducer shaft 19 in the short-track vehicle test wheel set assembly is shorter than that in the long-track vehicle test wheel set assembly, so that the synchronous belt 2 is convenient to install and test. The two single simulation test assemblies 1 are symmetrically arranged, and the short synchronous belt is arranged on the synchronous belt wheels 22 on the same side in the two long-track vehicle test wheel pair assemblies; the long synchronous belt is arranged on the synchronous pulley 22 on the same side of the two short-track vehicle test wheel pair assemblies. The short synchronous belt and the long synchronous belt can respectively provide power for the connected short driving wheel shaft assembly and long driving wheel shaft assembly under the drive of the driving motor 23, and the rotation directions are the same during the test.
Referring to fig. 15, the bogie converting body 4 has two groups of tested wheel pair assemblies 29 and a bogie motor 30. The effect of the bogie motor 30 is that in the event of a loss of energy, the missing energy is supplemented by the bogie motor 30 through the test piece wheel set assembly 29. The test piece wheel set assembly 29 is in rolling contact with the drive wheel shaft assemblies 7 in the two single simulation test assemblies 1, and can drive the rest to rotate together when one of the test piece wheel set assemblies rotates.
Working principle of closed loop simulation test bed of railway vehicle:
The motors of this design are all asynchronous motors. When the asynchronous motor is connected with an alternating current power supply, the asynchronous motor is a motor, and the principle is as follows: the stator generates magnetomotive force and generates a rotating magnetic field by flowing current through the stator. According to the law of electromagnetic force, a current-carrying rotor conductor is subjected to electromagnetic force in a magnetic field to form electromagnetic torque so as to drive the rotor to rotate, and when a mechanical load is carried on a motor shaft, mechanical energy is output outwards. When the current is reduced and the rotation speed of the stator is reduced, the rotation speed of the rotor is unchanged, the rotor rotates in the stator to cut the magnetic induction wire, thereby generating induction potential, leading out the induction potential through the wiring, generating current, and the asynchronous motor is a generator.
Referring to fig. 1 and 2, according to the design characteristics of the closed loop simulation test bed of the railway vehicle, when an experiment starts, four actuator assemblies 5 vibrate to drive a rail wheel supporting frame assembly 6 to vibrate, so that a single simulation test assembly 1 and a bogie rotating assembly 4 are driven to vibrate, and a rolling and vibrating movement mode of the closed loop simulation test bed of the railway vehicle is realized.
The bogie motor 30 in the bogie conversion body 4 is turned on, and the test piece wheel set assembly 29 is rotated. Because the tested piece wheel set assembly 29 is in rolling contact with the vibration track wheel 20 in the driving wheel shaft assembly in the single simulation test assembly 1, the tested piece wheel set assembly 29 rotates to drive the vibration track wheel 20 to rotate, so that the reducer shaft 19, the trapezoidal tooth synchronous pulley 22, the synchronous belt 2 and the driving motor 23 are driven to rotate, the driving motor 23 is discharged, and the symmetrically placed single simulation test assembly 1 and the bogie rotating assembly 4 start to decelerate. At this time, the driving motor 23 in one single simulation test assembly 1 is converted into a motor by a generator to provide rotating power for the speed reducer shaft 19, so that the rotating speed of the vibration track wheel 20 and the trapezoidal tooth synchronous pulley 22 is increased, and the speed reducer shaft 19, the trapezoidal tooth synchronous pulley 22 and the vibration track wheel 20 in the other single simulation test assembly 1 are driven by the synchronous belt 2 to be increased, so that the rotating speed of the tested wheel pair assembly 29 and the bogie motor 30 in the bogie rotating assembly 4 is driven to be increased, and the bogie motor 30 is converted into a generator by the motor to be discharged, so that a closed loop is formed. This process must have a loss of energy that is replenished by the bogie motor 30.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
