DEVICE RECORDING MAXIMUM ACCELERATIONS Russian patent published in 2000 - IPC

FIELD: measurement technology, recording of maximum accelerations acting within specified time interval in various directions. SUBSTANCE: inertial element of device fabricated in the form of permanent magnet having shape of disc is placed on one side of flat non-magnetic base. Section of base surface located under disc has minimal friction factor and base surface surrounding disc is made in the form of ring concentric sections which friction factors grow sequentially towards periphery and is fitted with ring and angular scales. Threaded bushing with ferromagnetic nut screwed on it that can be fixedly displaced relative to base is attached to base on its other side. EFFECT: increased reliability and simplified design of device. 3 dwg
