Embodiment Construction
[0036] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:
[0037] The pantograph-catenary relationship test bench of the present invention can simulate six degrees of freedom of the power grid, simulate the airflow received by the locomotive when the actual line is running, and simulate the mass distribution of the whole vehicle, thereby completely simulating the pantograph-catenary relationship on the actual line of the locomotive.
[0038] refer to figure 1 , the pantograph-catenary relationship test bench is mainly composed of a foundation 1, a gantry 2, a six-degree-of-freedom simulation power grid device 3, a test vehicle body pantograph operation posture simulation assembly 4, an accompanying test pantograph assembly 5, and a simulated airflow Formula blower assembly 6 and motor transmission connection device 7 are formed.
[0039] The gantry 2 is fixedly installed on the foundation 1 by bolts, and pr...

The invention provides a rail vehicle test stand to solve the technical problem that the existing test stand cannot completely simulate the pantograph-catenary relationship on the real track of the locomotive. The gantry of a pantograph-catenary relationship test bench is fixedly installed on the foundation by bolts, and the six-degree-of-freedom simulated power grid device and the pantograph assembly are fixedly installed on both sides of the right column of the gantry of the gantry; the installation of the two The location must ensure that the slide plate of the pantograph accompanying the test can be in contact with the high-voltage wire when the bow is raised; the pantograph operating posture simulation assembly of the test vehicle body is installed on the foundation through the actuator in the six-degree-of-freedom motion platform, simulating the airflow fan The assembly is fixedly installed on the horizontal beam of the gantry frame and the top of the gantry column; the motor drive coupling device is fixedly installed on the foundation through bolts. The invention can fully reproduce the movement posture of the catenary in the actual line operation, simulate the operation state of the pantograph in the actual line operation, and make the research on the pantograph-catenary relationship closer to the real situation.
Description
technical field [0001] The invention relates to a rail vehicle test bed, more specifically, the invention relates to a pantograph-catenary relationship test bed. Background technique [0002] At present, China's railways are in a period of vigorous development. As the speed of high-speed trains continues to increase, more and more problems need to be solved urgently. Pantograph-network relationship is one of them. The pantograph in high-speed operation obtains electric energy through sliding contact with the contact wire and transmits it to the electric locomotive. Good pantograph-catenary performance is one of the important guarantees for fast, safe and efficient railway operation. [0003] At present, many foreign countries have built high-speed railway pantograph-network relationship test bed. The wear test bench of Politecnico di Milano in Italy can carry out a large number of basic tests according to the combination of different locomotive speeds, different pantograph ...
