The design of intermittent-motion linkages using traditional methods is usually complicated. In this paper, (1) a new method for realizing intermittent motion, using linkages with a slight difference in length between links, is studied; (2) some new types of intermittent-motion linkages and their software for visual analysis and design are developed; and (3) influences of some design parameters on intermittent-motion characteristics are clarified. Results confirmed that the theory and the software are useful, making the synthesis of intermittent-motion linkages clear and easy.

我国海洋温差能资源量巨大,主要分布在广东省和南海海域,是区域能源结构优化以实现碳达峰、碳中和的有效支撑,也是未来我国南海、 21 世纪海上丝绸之路沿线诸多岛屿能源补给保障的重要途径;目前海洋温差能发电( OTEC)技术和装备尚处于实验阶段,兆瓦级试验电站建设成本巨大,整体技术成熟度不及商业级利用规模,亟待发展突破。本文总结了国内外 OTEC 及综合利用的发展模式、技术装备所面临的挑战,针对南海温差能资源开发困境、广东省液化天然气( LNG)冷能资源浪费等情况,提出了以 LNG 气化的低温海水替代深层海水进行温差能发电的新途径。建议以珠海 LNG 气化站为例,探索 LNG 冷能回收 – 温差能发电、低温冷海水综合利用示范基地的发展模式;通过初步概算示范基地的投资与收益,完成了相应模式的经济与技术可行性论证。相关发展模式建议、应用案例论证过程,可为我国温差能与低温海水资源综合利用提供技术借鉴和应用参考。

The objective of this study is, to interpret the influence of reinforced concrete walls addition in reinforced concrete frame structures considering behavior laws that reflects the actual behavior of such structures, by means of Castem2000computer code (pushover analysis). A finite element model is proposed in this study, using the TAKEDA modified behavior model with Timoshenko beams elements. This model is validated initially on experimental model. Then the work has focused on the behavior of a RC frame with 3 levels and three bays to better visualize the behavior of plastic hinges. Once the plastic hinge control parameters are identified (plastic rotation, ultimate curvature), a strengthening by introduction of reinforced concrete walls (RC/wall) at the ends of the reinforced concrete frame (RC/frame) has been performed. The results show that these RC walls significantly improve the behavior, by a relocation of efforts towards the central part of the beams.
