This paper reports results of the authors’ studies on the virtual design method used in the development of low noise intake system of I.C. engine. The resulting high pass-by noise at level above the legislative target at full throttle when engine speed was around 5200 r/min necessitated a BEM-aided redesign task, following the typical process of design and development of an intake system. During the initial design, based on the acoustic theory and the requirements (1. The air flux of the redesigned should equal to or exceed the value of the original flux; 2. The filtering area must not be degraded), and considering the constraint of space in the engine compartment, total volume and rough internal dimensions were determined. During the detailed design, the exact internal dimensions of the air cleaner were determined, and an effective method was applied to improve the acoustic performance at low frequency. The predicted sound power of the intake system indicated that the objective of reducing the overall engine noise by minimizing intake system noise was achieved. 展开更多

A good cooling circle should ensure that the system can work at an appropriate temperature in the requirements of power increase,engine compartment constraint and working demands for modern engineering machinery,which asks for a thorough understanding of system thermal loads before practical production.However,traditional experiment method spends a long time,costs a huge resource but lacks efficiency,whereas virtual design can avoid the shortcomings of traditional method and can analyze operating states adequately with variable loads on engine,generator,drives,battery pack and HVAC systems.Therefore,this paper focuses on a new virtual design method based on multi-dimension coupled simulation adopting Flowmaster software for initial prediction and CFX tool for further optimization.The simulation results in different operating conditions are compared and validated with experiments.Orthogonal experiment and range analysis are used to explore key parameters of cooling system.The research will be helpful in guiding future design and optimization of engineering machinery. 展开更多

To support modular fixture assembly design in virtual environment,a multi-view based modular fixture virtual assembly model is proposed.Instead of squeezing all assembly related information into a single model,three complementary views of assembly model,element information,function and structure,and assembly relationship are proposed to be used.The first view contains the detailed element information,while the other two explicitly capture the hierarchical function relationships and mating relationships respectively.These views are complementary in the sense that each view only contains a specific aspect of assembly related information while together they include required assembly related information.The proposed assembly model is specialized to accommodate the features of modular fixture virtual assembly design and applied in our developed prototype system. 展开更多

The architecture,engineering,and construction(AEC)industry is undergoing a substantial change,and the tech-nological advancements are shaping the future of this industry.Over years,numerous tools have been developed based on building information modeling(BIM)and the Internet of Things(IoT)to manage a variety of tasks and activities within different construction and operational phases in the AEC industry.Recently,with the advent of novel internet-enabled technologies in providing the ability of real-time connectivity,researchers have started to develop virtual design and construction(VDC)and digital twin approaches to remotely monitor,control,and optimize different work progresses and activities in real-time at any work level in the AEC industry.This paper presents a reference model to illustrates the main advantages and applications of VDC and digital twin,and to demonstrate their trends and anticipated cost savings in the AEC industry at a global level.These technological advancements along with augmented reality(AR)and virtual reality(VR)can offer the unique benefit of real-time monitoring of the current status as well as predicting the future of any physical structure at any level of work.The global demand and usage of these technological advancements will lead to great cost savings in the AEC industry which would be US$950 million in design and construction and US$400 million in operation and maintenance phases in the non-residential AEC industry in 2025.This paper also discusses the future challenges of VDC and digital twin in the industry.As a main line of future research,these technologies can simultaneously be utilized with artificial intelligence to enable human-centered decision making to automate and optimize work progresses.Such integrations of VDC,digital twin,artificial intelligence,and human-centered approaches will shape the future of the AEC industry and provide numerous research opportunities in this domain. 展开更多

Ongoing global architectural agendas span climate change,energy,a carbon-neutral society,human comfort,COVID-19,social justice,and sustainability.An architecture studio allows architecture students to learn how to solve complicated environmental issues through integrated thinking and a design process.The U.S.Department of Energy’s Solar Decathlon Design Challenge enables them to broaden their analytic perspectives on numerous subjects and strengthen their integrated thinking of environmental impacts,resilience,sustainability,and well-being.However,the unprecedented impact of the global COVID-19 pandemic transformed the physical studio-based design education system into an online-based learning environment.Mandatory social distancing by the global COVID-19 pandemic restricted interactive discussions and face-to-face collaborations for the integrated zero-energy building design process,which requires features of architecture,engineering,market analysis,durability and resilience,embodied environmental quality,integrated performance,occupant experience,comfort and environmental quality,energy performance,and presentation.This study emphasizes the educational effectiveness of virtual design studios as a part of the discourse on architectural pedagogy of zero-energy building(ZEB)design through integrated designs,technological theories,and analytic skills.The survey results of ten contests show educational achievement with over 90%of the highest positive tendency in the categories of embodied environmental quality and comfort and environmental quality,whereas the positive tendency of educational achievement in the categories of integrated performance,energy performance,and presentation were lower than 70%.The reason for the low percentage of simulation utilization and integrated performance was the lack of a proper understanding of and experience with ZEB simulations and evaluations for undergraduate students.Although VDS is not an ideal pedagogical system for the iterative design critique process,it can support the learning of the value of architectural education,including integrative design thinking,problem-solving skills,numerical simulation techniques,and communicable identities through online discussions and feedback during the COVID-19 pandemic. 展开更多

Natural products（NPs） have long been recognized as a valuable resource for drug discovery, and bringing NP-related features to virtual libraries is believed to be an effective way to increase the coverage of druggable chemical space. Here, deep learning-based molecule generative model, which is a recent technique in de novo molecule design, was applied to generate virtual libraries with NP-like properties. Results demonstrated that the model was effective in generating molecules that highly resemble NPs. Moreover, the model was also found to be capable of generating NP-like molecules that were also easy to synthesize, significantly increasing the practical value of the compound library. 展开更多

Engineering design is a resource intensive process with over half of a product’s total cost being attributed to design stage decisions. Developing product designs often involves creating complex 3D models in a 2D environment, a non-trivial task. This paper details a proof of concept VR environment displayed in a commodity HMD, specifically the HTC Vive. The environment allows a user to create full-scale, 3D, product geometry at the conceptual phase of the design process. The conceptual design environment contains a World-in-Miniature (WIM) model for enhanced usability. This method allows a user to efficiently manipulate full-scale geometry by adjusting the corresponding parts on a WIM model. Free-form mesh deformation was also implemented to provide designers with flexibility and efficiency not found in traditional design packages. Vital design metrics (e.g., cost, weight, and center of mass) were incorporated to allow a user to perform preliminary design analysis to assess product feasibility. Throughout the development process, the unique challenges and affordances associated with commodity HMDs were identified, explored, and discussed in this paper. Ultimately, the VR application discussed in this paper allows the user to easily create, assess, and view conceptual 3D designs without the constraints of traditional CAD software. 展开更多
