ディーゼル・ガス機関の振動測定と評価 Measurements and Evaluation of Mechanical vibration on Diesel and Gas Engines.
Measuring and evaluating method for a vibration of the internal combustion engine is highly developed through measuring machine histories-such as from the mechanical type to the electric type with a piezoelectric element as a transducer, and to the more improved type with a built-in FFT which can be analyzed into a frequency level. However, it has not been reached enough level quickly to measure/evaluate at the site.<BR>We started to investigate in 1993 (H.5) how the vibration of a combustion diesel/gas engine with a φ 160mm to 300mm cylinder influenced on required accessories as a damage, and tried to develop a new vibration indicator for an actual operation use, which was introduced a measuring/evaluating method using the 'Vibration Severity Grade' that ISO was reviewing at that time. New vibration indicator were adopted to some factories for their outgoing inspections and got good results. Followings are the histories and results of it.
