A METHOD FOR THE MEASUREMENT AND ANALYSIS OF RIDE VIBRATIONS OF TRANSPORTATION SYSTEMS

THE MEASUREMENT AND RECORDING OF RIDE VIBRATIONS WHICH AFFECT PASSENGER COMFORT IN TRANSPORTATION SYSTEMS AND THE SUBSEQUENT DATA-REDUCTION METHODS NECESSARY FOR INTERPRETING THE DATA PRESENT EXCEPTIONAL INSTRUMENTATION REQUIREMENTS AND NECESSITATE THE USE OF COMPUTERS FOR SPECIALIZED ANALYSIS TECHNIQUES. A METHOD IS PRESENTED FOR BOTH MEASURING AND ANALYZING RIDE VIBRATIONS OF THE TYPE ENCOUNTERED IN GROUND AND AIR TRANSPORTATION SYSTEMS. A PORTABLE SYSTEM FOR MEASURING AND RECORDING LOW- FREQUENCY, LOW-AMPLITUDE ACCELERATIONS AND SPECIALIZED DATA-REDUCTION PROCEDURES ARE DESCRIBED. SAMPLE VIBRATION MEASUREMENTS IN THE FORM OF STATISTICAL PARAMETERS REPRESENTATIVE OF TYPICAL TRANSPORTATION SYSTEMS ARE ALSO PRESENTED TO DEMONSTRATE THE UTILITY OF THE TECHNIQUES. /AUTHOR/
