To solve the defects of control vertices distribution which was one of the basic issues in CAD free curve fitting, a new interactive fitting technology of free curve fitting was presented. The density and distribution of the control vertices, which decided the shape of free curves, were planned manually with interactive processes, so that the quality of the control vertices distribution was guaranteed. The position of control vertices was adjusted automatically and iteratively to satisfy the approximation criteria. Applications show that both efficiency and quality of the fitting operation were satisfied very well.

In this paper, an optimized method of orthogonal experiment design is studied to determine the processing parameters in order to minimize the warpage of the supporting-foot plastic part. Considering the injection processing parameters such as melt temperature, mold temperature, injection time, packing pressure and packing time, a series of CAE simulation experiments are applied to reveal the warpage. The relative significance of each processing parameter on warpage is also acquired based on the range analysis of the results. Finally, verification test with the optimal levels of the processing parameters is also carried out. © (2013) Trans Tech Publications, Switzerland.

Traffic congestion are prevalent in worldwide cities. The imbalance between demand and supply of urban traffic is the root cause of this problem. So taking effective measures to regulate traffic demand, and guiding the traffic problems of the supply and demand balance is the best way to solve traffic congestion. This paper improves the TDM measure, and combines with intelligent information platform for the design of a new urban transport demand management adaptability of dynamic traffic data analysis platform. The platform supported by the technology of wireless sensor communications, intelligent terminals, the Internet and cloud computing is facing with the dynamic needs of traffic flow and traffic congestion state to carry out the operations of spatiotemporal data mining, clustering, and track detection, and to apply it into the traffic hot spots, abnormal driving track, traffic congestion trends and traffic flow detection and analysis, which has a good reference value for the improvement of management and service level of traffic intelligent systems. © (2014) Trans Tech Publications, Switzerland.

In this paper, the research object is cycling equipment which is common fitness equipment. The dynamic characteristics of the cycling equipment were optimized in a virtual prototype, and analysis was carried out on its structural mechanical characteristics and dynamic performance, etc. The dynamic characteristics of this cycling equipment were obtained through modal, random response and harmonic response analyses, and the structural reasonability after optimization was verified. This can avoid unreasonable design of the cycling equipment, and an effective analysis and assessment method for cycling equipment design was proposed. © Zhuang Min.

For a construction engineering project, the management of cost control is the most important thing and it throughout each part of the construction engineering. Effective cost control of engineering project can bring great benefits for engineering project in terms of economy, but with the improvement of people's requirements in buildings' function, appearance and comfort, the additional information on the construction project is growing, especially for some large-scale projects, there are more construction units, long construction period and large amount of information. Using the cost control of traditional model can lead to workload and can easily lead to loss of control, resulting in unnecessary waste. In this paper, on the basis of reading a lot of literature and referencing previous research results, a project is regarded as a study object. It combines the cost control and BIM technology to analyze the different roles of BIM technology at the different stages of engineering project. Through comparing with the cost control of traditional mode, it illustrates the advantages of BIM technology. Finally, it concludes the application status of BIM technology in the current engineering project cost control, hoping to strengthen the combination of BIM technology and engineering project cost control.
