Research on Stochastic Finite Element Reliability Analysis Method of the Structure for the Truck Crane Boom

摘要

The telescopic boom of truck crane has bearing and luffing functions. It not only requires higher carrying capacity, but also requires higher reliability in the various working conditions. For scientific evaluating the reliability of the telescopic boom structure, the stochastic finite element method is used to calculate the structure performance function probability. Taking 50 t truck crane telescopic structure as an engineering practical example, the feasibility and practicability of the method have been verified (tested/proved).
