ANALOG COMPUTER, SPECIALIZED FOR PROCESSING THE RESULTS OF MEASUREMENTS,
Abstract
General ideas underlying the design of special-purpose analog computers are set forth. A principle of simplified-to-suit-specified-accuracy equipment was used in the development of a special analog computer (SAC) for statistically processing the results of measurement of deformations of automobile tires. Three axial deformations measured by strain gages on a running tire (and converted into voltages) were recorded on magnetic tape. These measurements were applied to the SAC which calculated two principal deformations and two stresses. All 7 parameters were fed to a multichannel amplitude analyzer which determined the distributions of their maxima, minima, and spread over 1000 revolutions of the tire. The SAC comprises 15 operational amplifiers and one nonlinear unit; its overall error is 3 percent. Each SAC unit has a gain of 250 at zero frequency and a reduced-to-grid zero-point drift of 3 mv for 30 min; a passband for a 100-v sinusoidal signal is 65 kHz.
