Abstract

The invention relates to an integrated optimization method and an integrated optimization system for a static model of a fully-extending boom of a crane. The integrated optimization method comprises the following steps of 100, performing optimization integrated by virtue of ANSYS software and ISIGHT software, and parsing an input parameter in an input file required by the establishment of a fully-extending boom model; 200, establishing the static model of the fully-extending boom by virtue of the ANSYS software; 300, performing joint simulation analysis to obtain an optimal solution to the static model of the fully-extending boom by virtue of the ISIGHT software and the ANSYS software. According to the method and the system, a global optimal solution capable of ensuring stronger structural strength of the fully-extending boom can be finally obtained, the overall size of the fully-extending boom is reduced, and good effects in practical engineering are achieved.

Description

technical field [0001] The invention belongs to the field of mechanical design and automation, and in particular relates to an optimization method and system for a full-reach arm integrated with ANSYS finite element analysis software using an ISIGHT multidisciplinary optimization platform. Background technique [0002] With the rapid development of industrial technology and the needs of social infrastructure construction, the use of truck crane booms is becoming more and more common. When the telescopic boom is fully extended, in its conventional design, the telescopic boom width, height and various The parameters such as the thickness of the jib are selected within a range of values ​​based on experience, which brings problems such as excessive cost consumption, waste of materials, long time consumption, and unreliable strength performance. The optimization of the telescopic boom should be designed with the goal of high load and light weight under the premise of satisfying ...
