Embodiment Construction
[0036] Below in conjunction with accompanying drawing and example the present invention will be further described.
[0037] Establishment of Optimal Model for Telescopic Boom
[0038] The present invention takes the SQS500A telescopic boom as an example, and the initial values of the parameters mainly involved are shown in Table 1;
[0039] Table 1 List of optimized front boom parameters
[0040]
[0041] During the working process of the boom, it is mainly necessary to consider the force of three parts: the vertically downward lifting weight F3, the maximum lifting weight of the design model in this embodiment is 20 tons, so take F 3 =200000N; The tension F of the rope along the direction of the boom to the tail of the boom 4 =F 3 / 6≈33333.3N; the weight of the boom itself G=ρvg, ρ is taken as 7800kg / m 3 , the input direction of the acceleration of gravity g in ANSYS is opposite to the actual direction of gravity. The modeling of the boom is as follows figure 1 As ...

The invention discloses an integrated optimization method of a telescopic lifting arm static model. Integrated optimization is carried out by means of an ISIGHT multi-disciplinary optimization platform and ANSYS finite element analysis software. Different analysis problems can be solved by integrating the ISIGHT optimization platform and the ANSYS analysis software, and solution strategies can be nested and combined at will. By means of intelligent exploration of design problems, novel design initial values are selected continuously, and simulation and optimization are automatically carried out. In the circulating and analyzing process each time, real-time monitoring can be achieved through ISIGHT, design parameter input and performance parameter output of products can be displayed in the process, and design personnel can conveniently monitor the input and the output. By means of optimization, a global solution which allows strength and rigidity of the telescopic lifting arm to be better is finally obtained, the size of the whole lifting arm is further reduced on the premise that bearing capacity of the telescopic lifting arm is guaranteed, and the method has a good effect in actual use.
Description
technical field [0001] The invention relates to an integrated optimization method of a telescopic boom by using an ISIGHT optimization platform to call ANSYS finite element analysis software, and belongs to the field of mechanical design and automation. Background technique [0002] With the social progress and the rapid development of science and technology, and driven by the needs of most industries and the high efficiency of operations, the use of telescopic booms is becoming more and more common. In the conventional design method of the boom, the width and height of the boom and various Parameters such as the thickness of the joint arm are selected within a range of values based on experience, which brings problems such as excessive power consumption, waste of materials, poor condition, and unreliable performance. The optimization of the telescopic boom should be designed with the goal of high load and light weight under the premise of satisfying the strength and stiff...
