Title: Yoshihiro Dozono: Innovator in Vibration Testing Technology

Introduction

Yoshihiro Dozono is a notable inventor based in Chiyoda, Japan. He has made significant contributions to the field of vibration testing technology, holding 2 patents that showcase his innovative approach to engineering challenges.

Latest Patents

Dozono's latest patents include a vibration testing apparatus and a vibration testing method. The vibration testing apparatus is designed for hybrid vibration experiments of structures. It involves shaking an actual model that simulates a portion of the structure while conducting vibration response analysis of a numerical model that simulates the remaining portions using a computer. The apparatus features loading members positioned near the actual model, with multiple vibrators that vibrate the model through these loading members. The vibrators are controlled to ensure that a distributed displacement is applied to the actual model rather than a point displacement.

The second patent, the adaptive control apparatus and shaking table, includes a feedback controller that generates a drive signal for actuators. This ensures that an inputted second command signal aligns with a response signal indicating the vibration state of the table. The adaptive filter has variable filter coefficients and is supplied with an external first command signal that indicates a target value of the response signal. This filter generates the second command signal by compensating for the transfer characteristics from the feedback controller to the table loading the specimen.
