To meet this challenge, a research project was supported by ministry of communication and bv shanghai zhenhua port machinery co. ltd. focusing on analysis of tdtcd ( traditional design theories of crane drums ) the paper has studied the impacts of features under the binding force of wire ropes, the end - plate and rope slot. this study is based not only on the thin shell theory and viscoelastic mechanics to calculate the strength and stability of drum, but also on an experiment with technology in " state of act "
本文結合交通部重點科技項目「港口起重機鋼絲繩傳動件高性能技術研究」和上海振華港機股份有限公司委託項目「起重機焊接捲筒極限壁厚研究」 ，針對起重機捲筒傳統設計方法偏於保守的情況，以薄殼理論和近代力學為基礎，以現代試驗技術為研究手段，對鋼絲繩緊箍力作用下的外載特性、端板、繩槽等因素對捲筒強度和穩定性的影響進行了系統的理論研究，在深入開展捲筒強度、穩定性和實驗模態分析等試驗的基礎上，提出了有別于傳統方法的捲筒強度、穩定性計算方法。 -
In theoretical analysis, finite element method is firstly used to solve the mechanical - electric coupling problems in a flexible plate with piezoelectric elements and to obtain structural vibration modal shapes. focusing on collocated type of piezoelectric sensors / actuators, the maximum determinant of fisher information matrix criteria is chosen as the optimization function and then simplified to determine an optimal principle for the best location of piezoelectric elements
本文研究柔性板振動控制中壓電元件的位置優化設計問題，針對壓電傳感器和驅動器的同位布置結構型式，將壓電元件的有限元分析方法與d優化設計準則相結合，直接利用結構的模態振型確定壓電元件在柔性板上的最優位置。
