Abstract:

Two methods were used to predict the reliability index of radio set ANURC-32. The two methods of predicting equipment failure rates are basically similar. Each employs part failure rates in its calculations, weighted by such contributing factors as overstressed, defective, or misapplied parts faulty workmanship interaction of stresses and others not directly determined. Thus the final estimate of equipment failure takes into account conditions which could occur under field operating conditions. Before making the predictions, it was necessary to determine the level of various stress factors for a number of parts. The levels used were the sme as those produced under the reliability test conditions. About 958 electrical measurements were made, in addition to measurements of temperature of 60 different areas within the ANURC-32. Some 2383 electrical and hardware parts in the ANURC-32 were considered in the assignment of part failure rates. Author
