Reliability Analysis of a Two-Axis Flight Simulation Platform Based on DS Fusion Method

With the rapid development of the aerospace industry, aerial remote sensing stabilization platforms are widely used in navigation, positioning, and aerial photography. Due to various interferences, the reliability of these platforms can be significantly affected. To address the issue of large errors in the evaluation results of existing reliability analysis methods, this chapter proposes the use of the DS fusion method to analyze the reliability of a two-axis flight simulation platform. First, the mechanical components of the pitch and roll axes, as well as the electronic components of the platform, are analyzed. Then, using Dempster’s combination rule, the results indicate that the frame on the roll axis of the two-axis flight simulation platform is most prone to failure. By estimating the failure rates of each component, this method can more accurately assess the reliability of the two-axis stabilization platform, providing more reliable support for its practical application.
