Title: Mamoru Horiuchi: Innovator in Vehicle Noise Prediction
Introduction
Mamoru Horiuchi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of vehicle noise prediction through his innovative patent. His work focuses on improving the understanding and measurement of interior noise in vehicles, which is crucial for enhancing passenger comfort.
Latest Patents
Horiuchi holds a patent for a "Method of and apparatus for predicting vehicle interior noise." This invention involves a jig that is mounted on each of the four wheels of a vehicle. The jig is struck in three orthogonal directions independently, while a microphone inside the vehicle measures the sound pressure generated by the exciting force. An FFT analyzer is utilized to operate a frequency response function from the exciting force to the sound pressure. In a drum testing machine, a tire subject to noise prediction is mounted on a shaft, rotated, and the axial force in three orthogonal directions is measured. The axial force signal is input to the FFT analyzer, which operates the auto power spectrum in the three orthogonal directions and the cross power spectrum between two different axial directions. The frequency response functions are synthesized with the auto power and cross power spectrums, leading to the operation of the power spectrum of the road noise.
