Abstract: The grey system theory is adopted in the reliability analysis for modular optoelectronic pod, and a grey relational mathematical model is established. The sample modules are partitioned according to the category of index characteristics of reliability and the design requirements of optoelectronic pod, and the reliability index parameters of each sample module are evaluated. Based on the improved grey absolute relational analysis method, the resolution coefficient in the model is analyzed and calculated. Moreover, the correlation between the sample data line and the design standard line is expounded from the perspective of proximity, and finally the reliability analysis for modular optoelectronic pod is completed. The present optoelectronic pod modules are preferred based on the analyzed results of reliability to obtain the preliminary modular design scheme of optoelectronic pod. The two test prototypes are trial-manufactured according to the optimal and sub-optimal schemes. The reliability index parameters of each test prototype are tested and evaluated. It is found that the test results are consistent with the analysis results. The effectiveness and feasibility of the research method in shortening the product development cycle and studying the reliability of modular products are verified.
