The Control Strategy to the Integral Lifting Project of the National Digital Library's 10000-ton Steel Construction Roof

摘要

In the assembling process of the constructions of wide span and large space, ydraulic synchronizing integral lifting technology has been used more and more widely, and it is a vital subject to improve the reliability. In this paper, a successful application, that the integral lifting project of the national digital library's 10000-ton steel construction roof, is taken as a background. Against this background, the influence to the integral lifting caused by the construction's stiffness and stiffness coupling will be analyzed, and based on which an analyze of different control strategy will be taken furthermore.
