A HUMAN MODEL FOR MEASURING RIDE QUALITY

Desirable ride characteristics and acceptable noise and visual impacts on the environs all depend on basic decisions concerning vehicle design and maintenance, as well as on the structure and form of guideway for self-steering vehicles. This method for measuring vehicle ride quality can be used for all types of transportation systems. It is based on absorbed power, a method developed in the lates 1960's but not extensively utilized. Recent developments for handling random data have cast a new light on its use as a comfort criterion. Because amplitudes of motion, as well as frequency, are identified, it is easy to recognize what is causing ride deterioration. The system consists of a dummy which carries instrumentation to measure comfort parameters in three axes, although only the vertical axis presently simulates human response.
