三自由度并联式波浪补偿平台建模与仿真     

唐刚  胡超  胡雄 《上海海事大学学报》2020,41(1):20-26

鉴于船舶在波浪中的六自由度运动中,其升沉、横摇和纵摇运动对船舶工作平台上的设备影响较大,设计一种三自由度并联式波浪补偿平台来减少这种影响。通过对平台进行运动学分析,得到平台的运动学模型。利用ADAMS和Simulink建立带有控制系统时间延迟参数的虚拟样机模型,依据平台的运动学模型设计对船舶运动进行补偿的控制策略,并利用虚拟样机进行仿真,验证平台机构和相应控制策略对船舶运动的补偿效果。结果表明:当控制系统的时间延迟参数取值为1 ms时,平台对船舶升沉、横摇和纵摇运动的补偿效果分别为88.81%、95.44%和91.97%;当控制系统的时间延迟参数取值为0.1 ms时,平台对船舶升沉、横摇和纵摇运动的补偿效果分别为96.04%、99.07%和97.65%。由此可见:平台对误差有一定的包容性;可利用具有船舶运动预测功能的算法为平台提供超前的船舶运动数据或者提高控制系统的实时性来提高补偿效果。  相似文献

The role of a digital engineering platform in appropriating the creation of new work-related mind-set and organisational discourse in a large multi-national company     

《International Journal of Information Management》2019

This paper reports on a case study involving a strategic and innovative approach to creation of an in-house multifaceted digital engineering platform (the DEP) in overcoming a number of organisational problems at a multinational engineering company. The DEP was to be used strategically for simplifying the operational complexity and to create and appropriate new work-related mind-set and new organisational discourse to achieve homogenous working across the organisation, which is a huge challenge. The need for this system emerged from the need to resolve many organisational services related problems that carried phenomenal amount of processes, health and safety risks and to regulate, and, control the running of engineering project. Research data were collected using a longitudinal case study approach over a period of six months. In order to make sense of how the DEP helped the organisation, the study used certain elements of Extended Structuration Theory as a lens to assess the case study. This research discovered that the DEP succeeded in creating and appropriating work-related mind-set and organisational discourse. It also had real influence on working processes and employees at all levels while encouraging transparency, responsiveness, agility and accountability. It continues to help the organisation to govern, manage and maintain good standard of service but many barriers still remain.  相似文献   

Decoding digital transformational outsourcing: The role of service providers’ capabilities     

《International Journal of Information Management》2021

The business process outsourcing industry has got disrupted, first by the significant shift in value creation activities from the clients to the service providers, and second by pervasive digital penetration, resulting in the emergence of Digital Transformational Outsourcing (DTO). Service providers now play a more significant role, making their capabilities important. In the new context, service providers require a uniquely different set of dynamic capabilities to handle end-to-end business functions on behalf of their clients while delivering digital value propositions.We study 26 of the largest global business process outsourcing providers to conceptualise and identify six dynamic capabilities of service providers salient in the new context, i.e., consultative, orchestration, insights, network management, knowledge access, and standardisation. Interviews conducted with industry experts provided evidence in support of the identified dynamic capabilities. A novel firm capability dataset was created using secondary data, and using fuzzy-set Qualitative Comparative Analysis (fsQCA), we identify configurations for high and low performance and find them to vary by the firm's broad/narrow scope.  相似文献

Postural balance and rifle stability in a standing shooting position after specific physical effort in biathletes     

Dorota Sadowska  Justyna Krzepota  Andrzej Klusiewicz 《Journal of sports sciences》2019,37(16):1892-1898

The aim of the study was to evaluate the effect of maximal specific physical effort on postural balance and rifle stability in biathletes in a standing shooting position. The study included 10 junior elite biathletes. The measurements were taken with the Vicon system and AMTI force platform. Postural balance and rifle stability characteristics were determined at rest as well as 1 and 5 min post maximal specific physical effort which was performed on a ski ergometer and continued until exhaustion. Maximal physical effort exerted a significant effect on all examined postural sway and rifle sway characteristics. The duration of the post-exercise changes was longer than 5 minutes. Higher post-effort rifle sway was observed in the vertical direction than in the across the shooting line direction. Post-effort postural balance impairment in the shooting line was much greater than in the across the shooting line direction. Moreover, a strong correlation was found between postural balance and rifle stability. Maximal physical effort influenced postural balance and rifle stability during aiming. Rifle sway during aiming in a standing shooting position seems to be coordinated with the postural sway of the biathlete’s body. Thus, an increase in postural sway contributes to greater sway and lesser stability of the rifle.  相似文献
