Shebanov O. Definition of standardized norms of dependability for precise technological machines (industrial robots as example)

Object of researches. Executive mechanisms of precise technological machines and device of industrial robots, the kinematics couples of which don't subject to a high dynamics toads, an aggressive influence of environment, an essential thermal influence, but subject to age processes. Methods of researches. The theoretic researches are based on utilization the principal thesis of machine dependability, of tribonics, of kinematics and dynamics of three dimensional mechanisms, of methods of mathematical modeling and computer programming. The exparimental researches were realize with the help of modern technical agents. Scientific value. For the difinition of standardizaed norms of dependability of precise technological machines and their standartization are offered and are grounded an approach with physical positions of failure, which are permited still on the project stage to take into consideration most completely the influence of design and exploitation factors. Were elaborated the method of parametr dependability prognosis of precise technological machines by that are accounted wear influence in kinematics couples to the output link position. In the model of transference prognosis in kinematics chains of executive mechanisms dependance on initial parameters, are iutilizated acyclic graphs and as the characteristics - parameters of state standards. Were offered the analytical method of possible partial compensation of transference account from accumulate wear in the kinematics couples of executive mechanism of industrial robot. Were elaborated the analytical model, which are permited to account of influence of elasticity and qwner oscillation of intermediate links to the transference of the output link of industrial robot. Were eaborated in the probability organization a matrix model for determination the operating time for failure of executive mechanism of industrial robot. Practical value. Were elaborated the method of dependability estimation of design of precise technological machines still on project decision stage, which are allowed to establish the optimum term of manage influence receive with intention of parameter failure inadimissible, to find an optimum of design on the base of prognosis data, to form the documentation on standardization of dependability norms. The results of researches are drived to the level, which allows utilization in daily of design and production practice.
