Abstract


With the growing of the tower crane production and ownership , various security incidents increasing number of this paper, in order to meet the requirements quickly and easily assess the security status of the large tower crane tower crane safety based on Web and SMS technology assessment management system solutions. Tower crane with the use of broad areas , long running time , the traditional method can only be evaluated to determine the security status of a single tower crane , it is difficult to achieve large-scale unified assessment . The system for these features , the Web, SMS and finite element technology at all times of the tower crane , full geographical and safely state assessment . The main work and results are as follows : 1 . Starting from the theory of fatigue analysis , fatigue life as a tower crane safety assessment based on the selected tower crane . SMS transmission has a full time , the full geographical reliable characteristics , the system uses SMS technology as a means of transmission , will be collected at the scene of the tower crane to the data stored in the system , as the fatigue life calculation basis . The system uses a Web site platform as a data input means , and the announcement of the results of the safety assessment of channels . The system uses parametric modeling thought , the actual structure of the tower crane abstract and APDL parametric modeling of the finite element model of the tower crane and the development of the entire system and the C # language . The system uses the finite element model of the tower crane , SMS data and the SN curve of the material , calculate the fatigue life of the tower crane . 6 . Pointed out the shortcomings of the system and areas for improvement . Finally, run and test the entire system , the results show that the present system the initial realization of the expected targets and design requirements , to achieve the requirements of the present research purposes .
