INSTRUMENTATION SYSTEM FOR MONITORING FORCES AND MOTIONS ON ARTICULATED VEHICLES

In order to monitor the forces and motions to which an articulated vehicle is subjected, a field data acquisition and reduction system has been designed. This report details the hardware and software design of the system. The on-board data acquisition unit is built around an RCA-1802 microprocessor and an Archive Sidewinder streaming cartridge tape drive. Data is presented to the tape unit through use of the microprocessor's direct memory access (DMA) capability. Circuit diagrams of the instrumentation system's major components have been included as well as a description of the user operational procedures. Data reduction, i.e., summaries and plots of the field data tapes, is performed on a separate computer system, configured around a Digital Equipment Corporation LSI 11/23 computer. A 10 megabyte Winchester disk and a second Archive Sidewinder streaming tape drive are provided for data storage; a floppy disk drive is also included. Details of the data reduction software are contained in this document. (FHWA)
