 note = {Three types of accelerometers are designed which are suitable to measure pitching and heaving of ship, ship's hull vibration and acceleration due to slamming in rough sea on board ship. In this paper the design details and the experimental results about these newly made accelerometers are described. In part I, there are described about type IIA and IIIA (both bonded wire strain gauge type) which are made to measure pitching and heaving acceleration and acceleration due to slamming. Their natural frequencies are 33 c/s and 14 c/s, and measurable ranges of frequencies are 1 to 7c/s and 1/10 to 4c/s respectively. CR networks are used to obtain the electrical output proportional to heaving displacement directly from the measured heaving acceleration. These accelerometers showed satisfactory results in " Ginga-Maru " experiment done in Jan. 1956 in North Pacific Ocean. In part II, descriptions about type IV and V (both bonded wire strain gauge type) are given which are made to measure ship's hull vibration. Their natural frequencies are both 30 c/s, with suitable damping by silicone oil, so as to make measurable range of frequency as 1 to 10c/s. These accelerometers worked satisfactory in vibration experiments at sea trial tests. In part III, details of newly designed DTF type accelerometer (differential transformer type) for ship's use and its amplifier are described. It's natural frequency is 16 c/s and this accelerometer showed excellent characteristics in its high sensitivity and stability., 正誤表: 正誤表あり, 資料番号: SA1511765000},
