Research of health status evaluation method for large electromechanical equipment
-
摘要: 根据大型机电设备健康状态评估的复杂性和影响因素的非线性、模糊性及灰度性特点，从设备的产品质量、运行工况、历史数据3个主要方面构建设备健康状态评判指标体系，并设计了基于模糊-灰度-变权求和的分层设备健康状态综合评估模型。选用矿用带式输送机对综合评估模型进行验证，结果表明，运用该模型得出的评估结果与设备实际运行情况相吻合，该模型对于大型机电设备的健康状态评估及安全生产具有一定的实际意义。Abstract: According to characteristics of complexity of health status evaluation of large electromechanical equipment, and nonlinear, fuzzy and grayscale of the impact factors, the paper constructed evaluation index system of health status of equipment from three aspects of product quality, operational states and historical data, and designed stratified comprehensive evaluation model of health status of equipment based on fuzzy-gray-variable weight summation. Mine-used belt conveyor was selected to verify the comprehensive evaluation model, and the results showed that the actual operation status of equipment was consistent with the results of assessment derived using the model. The comprehensive evaluation model has an important actual significance for health status evaluation for large electromechanical equipment and safety production.
