Determining water-cooled xenon lamp weather-resistant climate aging test chamber reliability indicators should be based on the reliability requirements proposed by the user, and then select appropriately according to the use of the development object. The reliability feature amount, determine the reliability indicator of the device, that is, the target value of the equipment reliability feature amount. If it is a fixed-time device that can be repaired, it is generally indicators with average failure working time (MTBF).
can also be used as an indicator using the reliability target value in the specified time. For example, the user can directly propose the MTBF of a xenon lamp to weather the climate aging test chamber, or the requirements of 1000 hours. Sometimes the user has raised that there are not more than 3 units in the year, which is actually a one-year reliability of 100 devices is not less than 97%. Here, it can be used as an indicator to use reliability, or it can be assumed that the distribution law of the device fails over time is an index distribution, and the object value of the corresponding MTBF index is obtained using the formula of the reliability function.Of course, if it is assumed to be other xenon lamps to weather the climate aging test chamber type distribution, the required MTBF target value is calculated using the corresponding formula. Equipment for discontinuous work is often used as an indicator. For non-repairable devices, average life can be used (
or the average working time before the failure. In summary, the method of determining the reliability indicators should understand the basic concept of each reliability mathematical feature amount and the relationship between each reliability mathematical feature amount, and then according to the relationship between the basic concepts of each reliability mathematical feature. The use of objects and the reliability requirements of the user are used as the reliability indicator of the equipment.?
