Abstract

The invention discloses an intelligent multi-curved surface detecting system and method of a railway vehicle. The system comprises: a measuring module for detecting a height value of a point to be measured on a bottom surface of a carriage; a wireless receiving module for transmitting received data to an industrial personal computer; and the industrial personal computer for remotely controlling and measuring the measuring module. The intelligent multi-curved surface detecting system disclosed by the invention achieves high-precision detection of planeness of the bottom surface of the carriagein a manufacturing process of the railway vehicle, and the stability of a reference plane is improved; and by means of a PSD detection with precision higher than 1mm, the accuracy of measurement datais improved.

Description

technical field [0001] The invention relates to an intelligent multi-curved surface detection system and method for rail vehicles, and belongs to the technical field of instrument part size detection. Background technique [0002] The pre-assembly of rail vehicle underframe is generally divided into three parts: floor mounting seat, underframe cold-proof layer, and aluminum honeycomb panel. The floor mounting seat is composed of two parts, the rubber seat and the adjusting rubber pad. All the sizes of the rubber seat are the same, and the whole rubber pad has several different thicknesses to compensate for the deflection of the car body and to ensure the overall stability of the aluminum honeycomb floor after installation. in a horizontal state. Before the pre-installation of the chassis of the rail vehicle, the height of the bottom surface of the carriage needs to be measured to determine the thickness of the rubber pad. The survey in the production workshop found that th...
