【Abstract】 The static margin of the railway vehicle is a basic condition to ensure the safe operation of vehicles. In view of the problems such as operation complex and low efficiency of the existing contact test methods,based on the demand of automatic detection,this paper designed a vehicle clearance gauge detection system using high-power ultrasonic. The paper introduced the detection principle and then according to the structure of the system gave the corresponding correction formula,and ensured the accuracy of the measurement results. The system has simple measurement process and high measurement precision; it has achieved the goal of automatic measurement and can meet the requirements of tunnel limit test well.更多还原
