Big businessman user and relevant unit pay attention to.Crane carries very numerous in daily work as large-scale lifting appliance
The task of weight.The article usually hung is all heavy expensive article, so guaranteeing the device security of crane especially
It is important.According to statistics, the annual crane injury accident death toll in China accounts for 15% left side of the dead sum of whole industrial enterprises
The right side, the annual crane accidents number of casualties rank first in all mechanical accident death tolls.From the hoisting machinery occurred in the past
Crash analysis, the reason of causing crane accidents, are mainly segmented into 3 aspects, i.e. hoisting machinery itself, human factor and pipe
The factor of reason.Wherein mechanical factor itself is mainly that mechanical equipment itself has design, manufactures that not good enough, working service is improper makes
At defect, make other factors in the state of very intact, it is also possible to great personal injury occur.
The mechanical analysis of structure sound is carried out to crane at present and mainly uses finite element analysis.Finite element analysis used
Software has ANSYS etc..By modeling and simulating method, realize to hoisting machinery, especially its metal structure intensity, rigidity, stabilization
Property and fatigue life etc. numerical analysis, realize the cross validation to security evaluation scheme and field test data.In order to meet
Hoisting machinery finite element analysis needs to carry out a large amount of d solid modeling and finite element modeling work.Due to (1) 3D solid
Modeling work amount is big, and under normal circumstances, the modeling period of high pedestal jib crane is 30 days；(2) the repetitive operation ratio in modeling
More, the every place's minor variations of structural parameters all may cause the reconstruction of entire model, waste plenty of time and energy；(3) it builds
Mould Software Specialty is strong, and to the more demanding of user, user is difficult to grasp in the short time and skillfully use, these are all
It is not high to will lead to security evaluation working efficiency.Therefore, to improve three-dimensional modeling speed, further improve the effect of security evaluation work
It is particularly important to carry out corresponding modeling method technical research for rate and quality.
Summary of the invention
It is an object of the invention to for modeling period in the high pedestal jib crane security evaluation work being previously mentioned in background
