The YL-1 has a performance of 4.2 tons for 500 km sun-synchronous orbit and 6.5 tons for low Earth orbit. The success of YL-1 has further enriched China's launch vehicle spectrum, and will facilitate the launch of medium and large satellites and satellite constellations. In this paper, the flight ballistic solution of YL-1 is introduced. The flight trajectory consists of seven flight segments. The trajectory design comprehensively considered the characteristics and safety requirements of the vehicle to achieve effective utilization of the performance. Through comparative analysis of the flight trajectory and the predicted trajectory, the result confirmed that the flight trajectory was consistent with the design results, the design methodology was correct, and the flight test met the expected requirements. Subsequently, the vehicle will be employed for commercial application launch services.展开更多

Currently there are only a few approved designing guidelines that practicing engineers can use to easily design industrial floors. Rather the best practice is that the manufacturers of certain products (concrete fibre reinforcement, dilatation joints) carry out the more or less professional designing. In addition, there are numerous incurring questions in connection with applying the internationally approved guidelines in terms of applicability and reliability. Our paper is based on years of experience in designing industrial floors. In the first part the main guidelines, their characteristics and opportunities of application are discussed. In the second part we take a closer look at the most common TR34 British guideline, presenting its most significant designing formulas, which support engineering practitioners in carrying out the design of industrial floors on their own. In the third part we demonstrate advanced finite element analyses, comparing results with real sized experiments and with results of the guidelines.展开更多

User centered design is a growing research field for product innovation which needs support from both design knowledge and research methodologies. Both TID and UCD focus on user＇s perspective when doing multi-disciplinary work. They take care of style, usability, and balancing the users need and reality. The skills from TID help design expression and realization to communicate effi- ciently with other participants by informative images and real prototypes. The methods from UCD help the idea generation and op- portunity discoveries by facilitating workshops and conducting interview with participants. TID and UCD represent different per- spectives of the subjective and the objective respectively.展开更多

As individual spontaneous behavior can sent especial meaning for industrial design, there is a great necessity for creating design guided by this behavior. The design method carries out in four steps, first step is to focus on the analysis of individual action phase, pay attention to the explora- tion of the relationship between actions and tool ,and then list the importance order in the action phase, the third step is to take out the in-depth anatomical analysis of the stage, analyze the reason of the operational difficulty .and at last carries out the design concept to resolve the problem. All in all, this method revolves around the main stage of spontaneous behavior, and analyzes it in interim and solves the problem in stage.展开更多
