DESIGN CRITERIA FOR HIGH-SPEED POWER-TRANSMISSION SHAFTS.
Abstract
Research was continued on the establishment of a design procedure for ultra-high-speed power transmission shafting. Amplitudes of vibration of high-speed shafts were obtained from labora tory experiments designed to determine the effect of (1) using a single damper near one end of the shaft (2) using two dampers, one near each end of the shaft (3) using various spring stants and damping coefficients in the damper-support assem blies. Measured amplitudes were compared with calculated voltage standing wave ratios, based on a transmission line analogy. The majority of this work was conducted on a 1/2-inch diameter steel shaft, 138 inches long, having fixed ends. Work on shafts having simply supported ends was also started. The design of a hypercritical shaft system for a Vertol Chinook helicopter was started along with a modelled shaft system which will be evaluated in the laboratory. The labora tory setup necessary to evaluate the effects of shaft torque, curvature, and vibration was com pleted together with analytical work to predict these effects. The design of a damper which will damp angular shaft motion as well as vertical motion was also completed. (Author)
