Abstract


All-terrain crane is a kind of high-performance products for both truck cranes and rough terrain cranes characteristics , superior maneuverability , all-terrain crane also large tonnage development, in order to meet the additional demand for lifting conditions . The Chinese market all all-terrain crane in 2003 , relying on imports since 2003 XCMG launch 25 tons all terrain crane , XCMG and 2008 Shanghai BUMA engineering machinery exhibition launched QAY400 and QAY500 all terrain crane , the 2010 Shanghai BUMA Chinese enterprises have XCMG , Sany exhibited kiloton all-terrain crane , Zoomlion Heavy Industry launched 400 tons , 500 - ton all-terrain crane , so far , China's all-terrain crane large tonnage has reached international advanced level . In the context of the rapid development of all-terrain crane , how to ensure the safety of products , stable and higher requirements on the technical aspects of foreign products can provide a reference to us , but the core technology of the product design still need to study . Large tonnage products in the scale of the boom structure , results on the complexity of the form and lifting conditions far from small tonnage cranes can be compared , the accurate calculation of the structural strength of the large-tonnage all terrain crane is an important step to ensure the quality of the product . This paper discusses the method is the use of the simplified beam model to calculate the crane boom structure , the limit load of equipment work considered in the calculation , consider the equipment under load deformation impact , its calculation accuracy is verified by experiments . In addition, in the previous analytical method performance calculation method based on the use of finite element model to calculate and extract performance control , lifting performance computing corresponding models under design , in order to achieve a multi- condition batch performance computing effectively improve the accuracy and speed of the design calculations . This set of programs has been applied in the development of large tonnage all terrain crane XCMG , and its effectiveness has been verified . In addition , the method of this set of procedures conducive to achieve parametric and parametric procedures in this program based on the finite element analysis for large tonnage all terrain crane has been completed and has been applied .
