Study on Reliability Sensitivity Algorithm of Small Component Thermal Ignition Device

摘要

Thermal ignition device is testing equipment of intrinsically safe electrical products about thermal igniting for small element. Its research and application is an important link in the development of energy control about energy storage components. The paper takes influencing factors as starting point to study on the reliability sensitivity of small component thermal ignition device. On the basis of analyzing uncertainty of the basic variables, the curves of the related input are fitted. Paper making a binary linear regression analysis method based on covariance of correlation input is proposed to modify the sensitivity. In order to verify validity and accuracy of reliability sensitivity analysis, sensitivity tests were carried out on small component thermal ignition device repeatedly. From the operation status and the experimental data, it is reasonable and feasible for optimizing the evaluation process and improving the verification efficiency.
