摘要

数字液压是一种离散技术,集成了先进的动态系统控制、数字电子和机器学习,以提高流体动力系统的性能、整体效率和可控性。提出并设计了一种机械驱动直列三柱塞变量数字泵。直列三柱塞泵结合复杂的机械和液压子系统和高度耦合的机构。在评估概念设计的可行性时,所使用的子系统的复杂性提出了挑战。因此,这项工作的重点是设计、开发和实现一个协作虚拟平台,该平台涉及一个利用混合现实(MR)技术展示数字泵内部机械结构的数字化模块。磁共振技术被认为是利用计算机和可穿戴设备在真实虚拟环境中人机界面的未来发展。这项技术允许运行模拟来检查高耦合系统的复杂性,比如数字泵,在这些系统中,理解物理现象太复杂了。开发的MR平台允许多个用户在同步沉浸式MR环境中协作,研究和分析泵设计的适用性和操作机制的充分性。协同磁共振平台是在Unity游戏引擎上设计开发的,采用Microsoft Azure和Photon Unity Networking搭建同步磁共振环境。该平台在数字泵设计上包含一个完全交互式的虚拟模块,使用微软的混合现实工具包(MRTK)进行开发,分多个阶段进行,并通过HoloLens 2 MR耳机部署在同步MR环境中。普渡大学进行了一项涉及71名参与者的研究。该研究的目的是探索协同MR环境对理解数字泵的复杂性和操作的影响。它还试图评估MR在促进流体动力利益相关者在同步数字现实环境中进行协作以研究、诊断和控制其复杂系统方面的有效性。71名参与者在体验了MR平台后设计并完成了调查。结果表明,大约75%的参与者对他们的整体MR平台体验表达了积极的态度,特别是对其身临其境的性质和它提供的同步协作环境的赞赏。超过70%的参与者认为,泵的协同MR平台对于研究和理解数字泵机械结构的复杂性和复杂性至关重要。总体而言,结果表明,MR平台有效地促进了复杂泵内部结构的可视化,检查了各个子系统的装配情况,并测试了复杂机构的适用性。

Mixed Reality: A Tool for Investigating the Complex Design and Mechanisms of a Mechanically Actuated Digital Pump
Digital hydraulics is a discrete technology that integrates advanced dynamic system controls, digital electronics, and machine learning to enhance fluid power systems’ performance, overall efficiency, and controllability. A mechanically actuated inline three-piston variable displacement digital pump was previously proposed and designed. The inline three-piston pump incorporates complex mechanical and hydraulic subsystems and highly coupled mechanisms. The complexity of the utilized subsystems poses challenges when assessing the viability of the conceptual design. Therefore, this work focuses on designing, developing, and implementing a collaborative virtual platform involving a digitized module showcasing the internal mechanical structure of the digital pump utilizing mixed reality (MR) technology. MR technology is acknowledged as the forthcoming evolution of the human–machine interface in the real–virtual environment utilizing computers and wearables. This technology permits running simulations that examine the complexity of highly coupled systems, like the digital pump, where understanding the physical phenomenon is far too intricate. The developed MR platform permits multiple users to collaborate in a synchronized immersive MR environment to study and analyze the applicability of the pump’s design and the adequacy of the operated mechanisms. The collaborative MR platform was designed and developed on the Unity game engine, employing Microsoft Azure and Photon Unity Networking to set up the synchronized MR environment. The platform involves a fully interactive virtual module on the digital pump design, developed in multiple stages using Microsoft’s Mixed Reality Tool Kit (MRTK) for Unity and deployed in the synchronized MR environment through a HoloLens 2 MR headset. A research study involving 71 participants was carried out at Purdue University. The study’s objective was to explore the impact of the collaborative MR environment on understanding the complexity and operation of the digital pump. It also sought to assess the effectiveness of MR in facilitating collaboration among fluid power stakeholders in a synchronized digital reality setting to study, diagnose, and control their complex systems. Surveys were designed and completed by all 71 participants after experiencing the MR platform. The results indicate that approximately 75% of the participants expressed positive attitudes toward their overall MR platform experience, with particular appreciation for its immersive nature and the synchronized collaborative environment it provided. More than 70% of the participants agreed that the pump’s collaborative MR platform was essential for studying and understanding the complexity and intricacy of the digital pump’s mechanical structure. Overall, the results demonstrate that the MR platform effectively facilitates the visualization of the complex pump’s internal structure, inspection of the assembly of each of the involved subsystems, and testing the applicability of the complicated mechanisms.
