With the rapid development of railway transportation, using a locomotive and vehicle rolling vibration test bench for dynamic simulation testing is one of the extremely important testing methods in the current locomotive and vehicle development process. The rolling vibration table simulates the dynamic changes of the actual track by applying excitation to a finite radius track wheel. The measurement error of the spatial geometric parameters of the track wheel has an undeniable impact on the bench test. This paper proposes a method for measuring the geometric parameters of a rolling vibration test bench for locomotives and vehicles. Using the perspective projection theory, a geometric parameter measurement model for the rolling vibration test bench is established, and a measurement system calculation program is developed to achieve high-precision measurement of the static geometric parameters of the rolling vibration test bench for locomotives and vehicles.
Key words: Rolling vibration test bench for locomotives and vehicles / track wheel / perspective projection theory
