The measurement of thermal cycle curves of a high-strength low-alloy steel (HSLA) subjected twin-wire submerged arc welding (SAW) was introduced. The thermal simulation test was performed by using the obtained curves. The impact toughness at −50 °C temperature of the simulated samples was also tested. OM, SEM and TEM of the heat-affected zone (HAZ) of some simulation specimens were investigated. The...
Instructions of wireless remote control is difficult to receive. A method is proposes in this paper. Wireless Intelligent Control based on GSM uses phone as its master controller, sends various control instructions through the voice or message. It has many advantages such as wide coverage, good reliability, easy maintenance and low cost and so on. It needn't specialized communications equipment and...
Mechanical products normally consist of multi-parameter mechanisms. The uncertain factors resulted from the quantity of parameters and complicity of inter-relations shall give rise to problems of large dimensional arrays. Moreover, optimal models often contain functions of distinctive property, therefore feasible optimal methods are hard to find. On the basis of analyzing the optimal design methods...
Along with the development of Internet and WEB Technology, Many academic journals have established their work Website on the Internet, using WEB-based contribute system to deal with manuscripts. But many small academic journals which affiliates to higher education of the local government have no enough financial resource. They cannot afford to purchase or develop such system. In addition, to go over...
The virtual driving safety warning system is employed to remind the driver of dangerous operations in virtual driving, which can help to form good habit in real driving. The system can be divided into the hardware and software system. The hardware system is used for collecting, processing and transferring the driving operations from the driver. And the software platform is constructed by Visual C++...
The paper presents a distributed interactive vehicle simulation system for driving training based on the distributed interactive simulation (DIS) technology. It describes the system requirements, presents the system design particularly the vision subsystem design, and discusses the key techniques for the implementation of the proposed system including real-time communication, model partition, and...
