Embodiment Construction

[0036] The present invention is described in detail below in conjunction with accompanying drawing:

[0037] The six-degree-of-freedom simulating catenary device of the present invention can simulate six degrees of freedom of the catenary, and can completely reproduce the attitude of the catenary in actual line operation.

[0038] refer to figure 1 , the six-degree-of-freedom simulated catenary device is mainly composed of a main disk assembly 1, a reduction gearbox assembly 2 and a six-degree-of-freedom motion mechanism assembly 3.

[0039] The six-degree-of-freedom motion mechanism assembly 3 is fixedly installed on the bogie parameter determination test bench through the left six-degree-of-freedom motion mechanism lower diagonal brace fixing bracket 16 and the right six-degree-of-freedom motion mechanism lower diagonal brace fixing bracket 17 at the bottom. The two sides of the column on the right side of the gantry, or by changing the structure of the lower diagonal brace...

Abstract

The invention relates to a six freedom degree catenary simulation device comprising a main disc assembly, a reducing gearbox assembly and a six freedom degree movement mechanism assembly. The six freedom degree movement mechanism assembly is fixed to two sides of a right gantry post of a steering frame parameter detection test bench through a bottom support; the reducing gearbox assembly is fixedly linked to an upper frame of a six freedom degree movement mechanism of the six freedom degree movement mechanism assembly; the hub of the main disc assembly is fixedly linked to a reducer rotary shaft of the reducing gearbox assembly through a key, the reducing gearbox assembly drives a main disc of the main disc assembly, the movement posture of the main disc assembly is controlled by controlling the rod extending amount of six actuators of the six freedom degree movement mechanism assembly, and the posture of the catenary is simulated during actual line operation. The device is capable of reproducing the moving posture of the catenary of actual line operation completely, material is saved, and cost is lowered.

Description

technical field [0001] The invention relates to a motion simulation device, more specifically, the invention relates to a six-degree-of-freedom simulation catenary device. Background technique [0002] The catenary is a power supply network built along the railway. It is a driving power supply device in the railway. Through it, it is in direct contact with the sliding of the pantograph, and the electric energy is transmitted to the electric locomotive. The catenary is an important part of the pantograph-catenary system, so a reasonable catenary model must be established when studying the pantograph-catenary relationship, and a simulated catenary device must be built on the pantograph-catenary relationship test bench. [0003] Generally, the main structure of the catenary simulation device adopts a rotating main disk, so that an infinitely long catenary can be simulated. In foreign countries, the main disk of the wear test bench of Milan Polytechnic University in Italy is mo...
