| Abstract: | To detect the rail vehicle body size and geometry quantity,this paper puts forward the gantry three coordinate measuring system based on laser ranging.It structurally uses the laser ranging sensor array assembled on the gantry and high precision linear guide to realize the linear motion of gantry.Through the point measurement of the laser ranging sensor array,the precise detection of the vehicle body can be achieved.According to the measurement requirement,finite element model of this measurement system is built to ensure the reliability of the physical construction. |
