ABSTRACT

For the widely used complex telescopic boom system of engineering machinery, a batch process method based on the nonlinear FEM analysis was presented to calculate the safety working space determined by the material strength. The analysis on the boom system of a large aerial platform showed that the geometric nonlinear effect resulted in a non-negligible additional bending moment and a significant reduction of working space. The method provides practical experience for the structure calculation of telescopic boom system in engineering application.
