This book was released on 1963 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Transfer Function Approximation Program (TFAP) is an IBM 7909 FORTRAN program which will compute the approximate transfer function for any linear pressure transducer system from the system's time response to a step input. Input data to the program contains information which specifies test conditions, information which defines the data range and density for the approximation, and information which specifies the amplitude of the time response at each of a number of equally spaced sample points in the time domain. Primary output data from the program contains the amplitude and phase of the approximate transfer function for the transducer system at equally spaced points in the frequency domain. With minor modifications, the program is adaptable to any problem which requires the computation of a linear system's transfer function from its time response to a known input. The program has been tested with time response data for an analytically known two degree-of-freedom system excited by a step input. The results of these tests indicate that the accuracy of the approximate transfer function is determined by the data sampling frequency and the data range. For sampling frequencies greater than twenty times the highest frequency of interest and a data range which includes the time response out to a point at which the time response has reached 99% of its final value, the approximate transfer function was found to be within .5% of its known value.

This book was released on 1963 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The equipment used in the Edwards AFB Dynamic Calibration Facility is described. The report explains the dynamic calibration procedure and gives detailed equipment operating instructions. A shock tube is used to excite the transducer under test. A flow diagram and detailed explanation of shock tube utilization is presented. The data recording system is diagrammed, in correct operating arrangement. In this group of equipment there are two blast velocity gages which are used to measure the velocity of the shock wave. These gages are placed in ports on top of the shock tube in the test section. The leads from the blast velocity gages are connected to a Berkeley time interval meter. The electrical pulse from either one or the other of the blast velocity gages is also used to trigger the oscilloscope sweep. A Polaroid camera is used to photograph the test transducers output on the scope screen. The Flying Spot Analog-to-Digital Converter reads the transducer response as re corded on a photographic transparency and converts the film record to digital form. The digital information is recorded on IBM cards and/or printed paper tape. Output data rate is 40 cards per minute when punching cards and a maximum of 300 points per minute otherwise.
