| Summary |
"A practical procedure for investigating the performance of a vibration isolation system under transient conditions is presented. For this investigation, an induction motor with an unbalanced rotor is studied during the period when it accelerates to its operating speed from rest. Using Newton's second law of motion, equations of motion are derived, first neglecting and then considering the effect of "inertia torque". This torque is produced by the inertia force resulting from vertical acceleration of the unbalanced mass. The equations are solved on a digital computer using the Runge-Kutta method of order 4. The results obtained are compared with those obtained using Simpson's and Runge-Kutta methods of order 4 of the Continuous System Modeling Program. For the case when there is no external load, an attempt was made to obtain the responses of the system by the Convolution Integral Solution of the K.A. Foss method. A study of steady state and transient analyses for "inertia" and "no inertia" cases is carried out. From the results obtained, graphs are plotted and guidelines useful for design of vibration isolators are given"--Abstract, leaf ii. |
