Finite Element Analysis and Experiment Study on the Lorry Crane Telescopic Arm

摘要

Traditional mechanics calculation and finite element analysis are performed to estimate the stress and distribution for each section of the telescopic arm in the operation of lorry crane. Through theoretical analysis, the working strength of the lorry crane telescopic arm can be obtained. Meanwhile experiment study is performed to verify the rationality of the finite analysis results, The results show that the telescopic boom has higher security, thus to provide theoretical support for design of the lorry crane telescopic arm.
