Optimization of the Regulated Maintenance Periodicity on Military Equipment Products Operated According to their Technical Condition

Abstract

The article is dedicated to the optimization problem of the regulated maintenance periodicity for military products operated according to their technical condition. The analytical method of optimization for the exponential law of the time distribution between failures and the numerical optimization method for the diffusion-monotonic law are taken into consideration. The search for the extreme value of the regulated maintenance periodicity for the diffusion-monotonic distribution law was conducted with the use of the numerical method applying Mathcad 15.0. The dependencies of both the technical utilization factor and its derivative on the regulated maintenance periodicity at certain values of the model parameters were obtained.

Analytical and Numerical Simulation for the Force of Adhesion of Reinforcing Rod With Concrete

“…0 operational equipment. In both cases, the condition of the road surface also largely depends on additional related mechanical factors and climatic conditions [2]. At the same time, full consideration of all these factors in the design of rigid pavement of airfields and roads does not allow to predict their durability at the stage of operation.…”

“…An experimental comprehensive study of the impact of various indicators is carried out by studying the problem of extracting the reinforcing bar from concrete [2]. Recently, not only experimental and numerical studies have become important for this task.…”

“…The integration constants These constants depend on the geometric and mechanical characteristics of the structural material of the reinforcing rod and the concrete block. Subsequent calculations showed that the empirical coefficient c also significantly affects the solution of the boundary-value problem ( 1) - (2).…”
