FEA modeling method of stamping machine has been carried out using "Yoshimura Yoshitaka" method for studying its dynamic characteristic, it provide an easy method for dynamic characteristics analysis to determine characteristic parameters. To validate the FEM results, modal parameters of the beam under the work conditions were tested based on the theory of modal analysis. The FEM results...
Taking the roof space truss structure of Shenzhen Citizen Center as the engineering background, a novel finite element model updating method for the large space steel truss structure is proposed in the paper. Among all the components, the numerical model's accuracy depends on the joint rigidity of the nodes. Thus the main purpose of updating is to determine the proper joint rigidity of all nodes....
Based on damage modes of container cranes under earthquake and the characteristic of over-span flexible structures, the anti-seismic design of such machines was investigated. Taking the first crane equipped with isolating device as an example, through dynamic analysis and simulating to anti-seismic crane flexible system under the earthquake and validating analysis and results though the earthquake...
In order to study damage of ancient buildings by the Wenchuan earthquake in China on 12th ,may 2008, we took Da-Xiong Palace which is 189 km far away from the epicenter as an example for analysis. Columns of the palace inclined very much by the earthquake. We used time-history method to simulate response of the palace to find out the main reason for the large inclination. According to characters of...
