With the rapid development of science and technology, material products have been growing in increasing diversity. The current society has entered the cultural and spiritual consumption era. People's product demands have exceeded the boundary of "serviceability", and emphasized more on interactive experiences between humans and products. As a product category, furniture has transformed from...
In recent years, with the urbanization process speeding up unceasingly, more and more people flow into the city, and traffic jams become one of the main factors restricting people's fast rhythm life. Urban viaduct appears at this background. The building method and application in construction of BIM-based urban viaduct family library is introduced in details, like classification of members in urban...
A dynamic analysis model of the novel lander is created, and all possible landing conditions at touchdown are considered. Through analyzing the landing process of free-fall landing mode, some shortcomings are found. To improve the landing stability of the novel lander, low-speed landing mode is proposed, namely, the main engine and attitude control engines are switched off soon after the lander is...
As a kind of semi crystalline thermoplastic engineering plastics, Polyetheretherketone (PEEK) has excellent mechanical properties and chemical stability. Aiming at the high temperature properties of PEEK, test and analysis of PEEK fused 3D printing performance was carried out by the fused deposition modeling(FDM), the experimental research date has been obtained by the effect of temperature on the...
In order to enhance operation safety of unit, at present, state monitoring of large-scale rotary machine has been universally applied. Failure diagnosis technology receives universal emphasis and it is continually developing from machine maintenance at fixed time to maintenance according to actual condition. With the development in communication and network technology, people are no longer satisfy...
This paper aims at proposing an improved generalized dynamic rollover threshold of multi-axial vehicles based on lateral load transfer ratio (LTR) and providing the foundation for rollover prediction. The study is carried out by utilizing vehicle handling dynamics to build a vehicle rollover model, which takes into account the characteristics of suspension and limit equilibrium of tires' lifting-off...
Internet of Vehicles is a special application of Internet of Things. In recent years, it has become an important symbol of the Smart City and Intelligent Transport System construction with increasingly attention from all circles at home and abroad. This paper is aimed to make an analysis and summary of the existing Internet of Vehicles technology, and expound the latest results and the product of...
In order to meet the need of terrain model in a ship driving simulation training system, a method of terrain modeling based on S-57 electronic chart is proposed to solve the existing problems. This method integrates three-dimensional terrain data generation technology, GPS positioning technology and GIS geographic information technology, and proposes a method of 3D terrain data generation, radar terrain...
More than 1 million people die from traffic accidents each year around the world, which has arose public concerns to the vehicle safety. This paper examines improvement plan on the existent system of avoiding automobile rear-end collision. Based on the distance measurement millimeter-wave radar, the paper make predictions about relative distance and speed of the vehicle and the external substrate...
In this paper, we provided a selective maintenance model for complex system with multilevel structure. Our selective maintenance model is so special that we consider the fact when a specific component is maintained so that the subsystems must be removed. We consider that the components have two kind of status, working or failed. We consider three different maintenance actions for the components with...
The driving mechanism of the control rod of the nuclear reactor is the only moving part, and the hook grippers are the key parts for the driving mechanism. Being in the trial production stage for domestic, the hook grippers' geometry size and the surface geometrical morphology need to be tested out for making sure whether it has met the requirements of the use of nuclear power plant reactor, whether...
The opening of the museum enriched the people's daily cultural life, and the way of exhibition also experienced the process of static, dynamic and interactive experience. In the Internet+, high-tech electronic information age, museum interactive design is an inevitable trend. From the perspective of the audience, interactive design combined with the psychological and physiological characteristics...
