Six degrees of freedom simulation catenary device

Abstract

The invention relates to a six-degree-of-freedom simulated catenary device. The device is composed of a main plate assembly, a reduction gear box assembly and a six-degree-of-freedom motion mechanism assembly. The six-degree-of-freedom motion mechanism assembly is fixed on the right side of the gantry column of the bogie parameter determination test bench through the bottom bracket. On both sides, the reduction gearbox assembly is fixedly connected to the upper frame of the six-degree-of-freedom movement mechanism in the six-degree-of-freedom movement mechanism assembly, and the hub in the main disk assembly is connected to the reducer shaft in the reduction gearbox assembly through a key Fixed connection, the reduction gearbox assembly drives the main disc in the main disc assembly to rotate, and controls the movement posture of the main disc assembly by controlling the rod length expansion of the six actuators in the six-degree-of-freedom motion mechanism assembly. So as to simulate the attitude of the catenary in the actual line operation. The invention can fully reproduce the movement posture of the catenary in the actual line operation, saves materials and reduces costs.

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...
