Abstract A General Vehicle Test System (GVTS) has been developed by the Transportation Systems Center, Cambridge, Massachusetts to facilitate rail transit vehicle testing at the Transportation Test Center, Pueblo, Colorado. This system was designed to be responsive to requirements specified in the publication GENERAL VEHICLE TEST PLAN (GVTP) for URBAN RAIL TRANSIT CARS, report - number UMTA-MA- 06- 00 25 75- 14 . This manual describes the GVTS instrumentation equipment and techniques to be used for vehicle tests. The GVTS includes measurement systems for vehicle volt- age, current, accel eration/ vibrat ion , pressure, temperature, displacement, strain and test reference data.

To facilitate rail vehicle testing at the Transportation Test Center in Pueblo, Colorado, the Urban Rail Supporting Technology Program of TSC has developed a General Ve- hicle Test System (GVTS) . This system includes instrumentation, digital data acquisition and processing equipment and certain special purpose measurement systems. The GVTS was designed to be responsive to requirements specified in the General Vehicle Test Plan (GVTP) for Urban Rail Transit Cars, document number UMTA-MA- 06-0025-75-14, September 1975. This manual describes the instrumentation equipment and the detailed techniques for ensuring the acquisition of valid test da- ta. The GVTS includes measurement systems for vehicle electrical current and voltage, acceleration/vibration, air pressure, equip- ment temperature, mechanical strain, displacement and test re- ference data such as vehicle speed and location. This work was performed under the direction of George Neat, Assistant Program Manager for Test and Evaluation for the TSC Urban Rail Supporting Technology Program. The equipment was de- signed by TSC staff member Phillip Silvia and the author. iii FACTORS ll 01 6! 9!
