摘要： PROBLEM TO BE SOLVED: To provide a means for testing vehicles under dynamic driving conditions by reproducing the driving conditions that are rapidly converted.
SOLUTION: A load motor 2 is directly connected to a drive wheel 11. Inertia components in an external mechanical load is limited to the one done by the rotor of the load motor 2. The influence of inertial force in a wheel contact roller 3 can be excluded as compared with a case where the load motor is directly connected to the wheel contact roller 3 as before, and a highly responsive pseudo load can be given to a wheel 10. The output of a compensation motor 4 directly connected to the wheel contact roller 3 is controlled based on the speed of the drive wheel 11, the inertial force in the wheel contact roller 3 is canceled out, weight in the wheel 10 is supported by the wheel contact roller 3, and the influence of inertial force in the wheel contact roller 3 to a drive wheel 11 is reduced.

SOLUTION: Three shafts, namely, an output shaft 12, a counter shaft 13 and a final shaft 14, provided in the transmission 10 are mutually connected through a pair of gears. The counter shaft 13 is torsionally excited by an exciter 21, to thereby generate a pseudo mating vibration between tooth flanks of a gear 12a and a gear 13a. The vibration level at each part of the transmission 10 relative to the generated pseudo mating vibration is measured by a sensor 23, and the transmission sensitivity of the gear noise at each part of the transmission 10 is evaluated based on the result of measurement.

摘要： PROBLEM TO BE SOLVED: To eliminate a background noise and accurately measure a sound transmission characteristic by generating a sound at one side of an object to be measured, collecting the sound at the other side, and extracting only a sound tuned with an intensity change of the generated sound from the collected sound. SOLUTION: A sound signal changing its intensity with time is generated by a modulator 17 of a sound generation part 12, radiated from a nozzle 36 of a sound source part 20, collected by a microphone 44 of a sound collection part 42 set in a vehicle room, and amplified by an amplifier 46. Then a frequency characteristic is analyzed by an FFT 48. The signal collected by the microphone 44 includes a background noise and a sound radiated from the sound generation part 12. Therefore, when analyzing the signal, the FFT 48 compares the signal with the reference signal inputted from the modulator 17 and having the intensity changing with time, and extracts only a signal component synchronous with an intensity modulation of the reference signal. A signal component without a synchronous intensity modulation, i.e., background noise is thus eliminated. The extracted signal component is accordingly almost from the sound radiated from the sound generation part 12 even when there are sounds of an equal frequency.
