摘要：
The reliability of boom crane structure determines the safety and performance of the whole machine. Due to the sample information of uncertain parameter is lacking, non-probabilistic reliability of boom crane structure under the condition of limited samples is studied. Considering the time dependent deterioration of structure resistance and the load time effect, the time-dependent uncertain parameters of boom structures are comprehensively analyzed. A time-dependent reliability model of boom structures based on interval non-probabilistic is proposed. Based on the theory of interval non-probabilistic time-varying reliability, an engineering example is analyzed by using VC++ programming. The influence of different weight and uncertain parameters on the structure reliability of the boom is analyzed. The results show that the resistance, attenuation coefficient, average resistance and non-probabilistic time-varying reliability indicators of the boom structure attenuate seriously after decades. The conclusion verifies the scientific of the proposed method on the time accumulation effect.
