Ancillary products will be the second method of life extension
Systems, components given life extension tests, the second supporting products also will be the test. As a long time power system components, plus the actual use of simulated rocking, vibration, etc.,[link widoczny dla zalogowanych], to a number of moving parts in more demanding conditions than the actual work of the state, therefore, can test, the use of engineering experience, analytical methods such as direct its the first turn of the assessment. In the application of this method, attention should be assessed a 28 second complementary products of a working condition in the experiment is consistent with the actual use, there is no assessment of their life to the role of specific subjects the situation. To SF as a 2C-type servo motor side, in the heading and attitude of HZX-l test system to be life extension, parts of which were equipped with 5 l5 only SF-2C type servo motor system goes through a field to use. Power company to work plus beep indicator, the impact of such pilot projects. TQZ-IA posture in which the whole combination of gyroscope placed in the platform swing to ± 2.5. Inclination, 4r/min swing speed. This allows gyro, indicator of the sF a 2c servo motor in a constant state of work and strict than the actual conditions of use. Throughout the testing process, SF has been working for a well-2C servo motor, without any failure, therefore, can be turned according to the test case of its first period (hours) directly assessed. For example, with engineering experience method T. A -. + Where _r - Test the deadline to ask: T. - Field use of time; K - empirical coefficient, whichever value is 1.2. 71 led turn on (working time) of the initial value,[link widoczny dla zalogowanych], in the To: 607 +: 4774h3 life extension test is given directly to the second supporting Test the product life extension and accordingly be turned on its first assessment of the method. In using this method, pay attention to the rational development of pilot programs,[link widoczny dla zalogowanych], to simulate actual usage as much as possible. If SF can not be energized for a servo motor idling 2C, while the need to bring TH-3 as the load gear. In addition, according to the stress level, cycle number, duration and other factors asked for conversion and the actual use, given an acceleration factor, is used to shorten the test time. For example, SF-2C-type servo motor during the test, in the apartment voltage, high speed,[link widoczny dla zalogowanych], continuous state, and in the system at a low voltage, low-speed intermittent work status, the unit, asked the rotation ratio of l : 500; Moreover, given SF a 2C failure mechanism of the servo motor, its life is mainly affected by temperature, load, time and other factors. The combination of these factors, through conversion, to get a speed factor 733. Therefore, to conduct the first turn + of 5000h (flight hours) argument, the test can only be 700k. (B) Engineering analysis a weak law that affect the life of the product through the main set of factors to determine the life of the product life extension of a method. For example, by analysis of a 2C-type servo motor sF major factor in life is oil. With the use of time, film damage, bearing steel is oxidized, increasing wear and tear caused damage. In the new long-term use of the lubricant is not available pending the development, through regular cleaning fuel to extend its life. 2 This analogy is based on the known life of similar products,[link widoczny dla zalogowanych], the structure, performance, reliability analysis, to determine the other model is better than the original model a method of life. For example, SF-2C is the SF-2B improved servo motor, using a ball bearing and an oil storage installation, resulting in improved product performance and life. The SF-2B 2 similar products sF a servo motor has been turned with the system the first period (calendar Q) 6 years of argument. Therefore, that structure, performance is better than a 2 sF sF 2c servo motor of a first turn of the (calendar time) up to 6 years. 3. Backstepping method which is based on the life of system components are known, through the logical decision. Against the introduction of a method of life of components. For example, for SF-2C-type servo motor, the individual components are not redundant design, SF a direct 2C servo motor performance of the fault component failure. So. Its reliability and life must be equal to or better than the system components. Accordingly. 2c can be introduced sF a servo motor on the first turn where the components must be equal to or greater than the period of the first turn. Fourth, review summary, the second set of products supporting the many ways life extension, life extension at its scheduled time, to fully consider its characteristics, economic rationality to formulate programs. In addition, with the maintenance, information system, improvement can also use the field of Information Act, leading to life using the law to be assessed with a wide range of life extension work, in depth, can also use a similar method on the new conversion method and the same for different models to assess product life.
