Overview of Accelerated Life Testing Procedures for Reciprocal Compressors
نویسندگان
چکیده
This article focuses on the understanding and discussion of accelerated life test (AL T) procedures applied to reciprocal compressors. AL T procedures were analyzed and classified according to time proportional and proportional hazard models. Many papers were published and extensive research has been done in the area of AL T procedures. However, the fast paced changing world demands for a new generation of AL T procedures that are able to give more detailed life estimates and focus on different compressor life periods beyond the warranty period. Leading compressor producers have know-how to succeed in this task, but the most successful ones will cover some basic tasks in the development of AL T procedures.

OPTIMUM GENERALIZED COMPOUND LINEAR PLAN FOR MULTIPLE-STEP STEP-STRESS ACCELERATED LIFE TESTS
In this paper, we consider an i.e., multiple step-stress accelerated life testing (ALT) experiment with unequal duration of time . It is assumed that the time to failure of a product follows Rayleigh distribution with a log-linear relationship between stress and lifetime and also we assume a generalized Khamis-Higgins model for the effect of changing stress levels. Taking into account that the...

< p>Accelerated Life Testing (ALT) is very important in evaluating the reliability of highly reliable products. According to ALT procedure, products undergo higher stress levels than normal conditions to reduce the failure times. ALTs have been studied for various conditions and stresses. In addition to common stress such as temperature and humidity, random usage can also be considered as anoth...

In many of the studies concerning Accelerated life testing (ALT), the log linear function between life and stress which is just a simple re-parameterization of the original parameter of the life distribution is used to obtain the estimates of original parameters but from the statistical point of view, it is preferable to work with the original parameters instead of developing inferences for the...
