In this study, we have developed a non-destructive inspection system for detecting external wall tile delamination by incorporating a pulse water jet impingement force into a suspended apparatus. The delamination inspection using a pulse water jet of

Autor: Masatsugu Ohno, Kei Nakatsuma, Yasutaka Ohshima, Ippei Torigoe

Publikováno v: SICE Journal of Control, Measurement, and System Integration, Vol 10, Iss 5, Pp 338-343 (2017)

The pressure change method of leak testing has the serious disadvantage of being susceptible to ambient temperature change. Two or more successive leak tests are typically performed to eliminate the error caused by such change. We propose a new leak

Pressure change leak detection using exponential analysis

Autor: Masatsugu OHNO, Kei NAKATSUMA, Yasutaka OHSHIMA, Ippei TORIGOE

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 83, Iss 851, Pp 17-00112-17-00112 (2017)

The pressure change leak test detects a leak from the pressure drop observed after the container under test is filled with compressed gas and then closed. This method has the serious disadvantage of being sensitive to the temperature variation in the
