is the simplest in this consideration an integral part of the product, consisting of one or more parts; system – a set of co-operating elements designed for self-performing the specified functions. The concepts of element and system transformirovalsya each other depen- ding on the task. Mechatronic module when establishing his own reliability is considered as a system consisting of separate elements – motion transducers, parts, etc., and in the study of the reliability of the robot as an element. Reliability is characterized by the following main States and events [22,23]. Performance – the state of the product in which it is able to normally perform the specified functions. Diagnostics – the state of the product, in which it satisfies all not only the basic, but also the auxiliary requirements. Fault – a condition in which it does not meet at least one of the requirements of technical documentation. Distinguish faults do not lead to failures, and neispravnostei their combinations leading to failure. Refusal – the event consisting in whole or in part from the waste of health. Their share of failures functioning in which the exercise of their functions of the considered element or object is stopped (for example, breakage of gear teeth), and parametric failures, in which some parameters of object change in inadmissible limits (for example, changing the precision of the mechatronic module). Failures are divided into flash (breakage from overload, jamming), the gradual development and sudden in its manifestation (fatigue failure, a burned out bulb, short circuit due to the aging of insulation) and gradual (wear, aging, corrosion, stiction). 240 The causes of failures are divided into structural, caused by a flawed design, technological, caused by the imperfection or disturbance technology, and maintenance caused by improper operation. Waivers in accordance with their physical nature are associated with the destruction of parts or surfaces (breakage, chipping, wear, corrosion, aging) or is not associated with destruction (blockage of flow channels of the working fluid in the hydraulic actuators, the weakening of the joints, contamination or weakening of the contacts). Possible further use of the product failures are divided into full, excluding the possibility of work products prior to their elimination, and partial, under which the product can be partially used. Complexity of elimination distinguish failures, disposable in the mainte- nance procedure, in the order of the middle or overhaul and elimination dispo- sable in the operating and stationary conditions. At the time of occurrence of failures is divided into the running-that occurs in the first period of operation associated with the lack of running and getting to the Assembly of defective elements; during normal operation (for the period before the appearance of wear failures); smoovie. жүктеу/скачать 11,25 Mb.
