Finite element modeling and strength analysis of boom system of concrete pump truck

摘要

Concrete pump truck plays an important role in national economic development and infrastructure construction. The boom system is one of the most critical parts of concrete pump truck, so it is important to analysis the strength. In this paper, the research is on the concrete pump truck of 37 meters. The three-dimensional model is established in PRO/E. Then the model is imported to MSC.PATRAN/NASTRAN and the strength is analyzed. The results show that the maximum stress on the boom is far less than the yield limit of the material, the structure meet the strength requirements.
