Many beam - arch combination system bridges ( bacb ) , as their good mechanical behavior , low cost , constructibility and beautiful appearance , have been built all over china in these years 梁拱组合体系桥梁近年来在我国发展迅速,由于其受力合理、造价低廉、施工简便、造型美观等特点,在公路建设中得到广泛应用。
Through a lot of simulation experiment and a brief theory inference , we conclude the character and quality of the combination system . the combination system has some great advantages , which is proved by the simulation experiment 主要通过计算机仿真实验的方法并结合了简化的理论推导,验证了此串级- smith混合系统实现的可行性,同时,对串级- smith混合系统的性能进行了深入的讨论。
This thesis mainly discusses the devices based on crystal optics and polarization , which includes polarization interference filter ( pif ) used in the separation and combination systems of lcos , achromatic wave plates based on the similar principal of pif and the crystal polarization beam splitter 本论文将主要讨论晶体偏振光学器件:用于lcos分合色的偏振干涉滤光片( pif ) ,基于pif原理的消色散延迟片和偏振分束器。
It ameliorates the disadvantages of the smith predictor from control method combinations , and then improves the robust - quality to parameter change . we also have a research about the combination system between the cascade control and the fuzzy control 模糊控制器是解决控制系统中大纯滞后问题的一个新的控制策略,本文提出了将模糊控制引入串级控制系统来优化串级控制系统控制品质的方案,即用模糊控制器来替代常规的pid控制器。
Cable stayed arch bridge as arched bridge with cable stayed bridge of combination system , its stability is an important link of design and construction . this paper studies the stability of cable stayed arch bridge , combined the main bridge model experiment of the fourth bridge of xiangtan xiangjiang river 斜拉拱桥作为拱桥和斜拉桥的组合体系,其稳定性是设计、施工中的一个重点环节,本文结合湘潭湘江四大桥主桥模型实验,对斜拉拱桥的稳定性作了一些具体研究。
