A hybrid model is constructed to illustrate the process of updating energy state and topology structure. Based on the model, a consensus algorithm for BMS is proposed. It’s useful for evaluating optimal utilization of battery management at design phase. Related analysis reveals that the energy state of discharge process in battery modules converges to balance. A prototype of simulation was developed according to the constructed model. Simulations results are presented that demonstrate the effects on the speed of consensus algorithms and cooperative control of battery modules.

Authors: Cheng Jin Xia
Published: June 2014

On the base of green design concept, multi-functional product design is given a new meaning. It is no longer simply a combination of multi-functional functions, but to extend product function on the bases of no extra cost and no waste of materials. Through fuzzy functional design, integrated design of related functions, developing the secondary function of product, as well as enhancing the product spiritual function and other ways, we can achieve multi-functional design of products.

The wind power is increasingly developed, and the tropical weather condition is a challenge for flexible wind turbine structure. It is essential to get the structure response of wind turbine under typhoon conditions, and then solutions to reduce the load should be found. This article firstly discusses characteristics of typhoon suitable for wind turbine loads calculation, and then a simplified model with two degrees of freedom is got in two directions separately, according to the experiences of high-rise structure to mitigate vibration and theory of vibration absorber, passive TMD systems are put to the wind turbine structures in longitudinal and lateral direction. After that a medium complicated aero-elastic software FAST-SC is used to simulate transient and also fatigue conditions, the tower top displacement and tower base bending moment are evaluated, TMD systems can help reduce the transient load and fatigue loads of flexible wind turbine structures.

Published: June 2014

To obtain the concise relationship between the dynamic load and its influence factors, the single degree-of-freedom system was applied to simplify the crane working mechanism. Based on the sloping load, this paper analysed the main influence factors on the dynamic load and two relations were obtained:the relation between the dynamic load coefficient and the loading time;the other between the dynamic load coefficient and the natural vibration period. Due to the previous calculation and analysis, the suitable loading time and the dynamic load coefficient within the engineering permissible range were also obtained. The stiffness formula based on the loading time of the system’s elastic component was originally put forward. The result provided not only reliable basis to obtain the geometric parameter of the elastic component, but also feasible measures to prevent the dynamic load from increasing. Hence, it is effective to ensure the stable running of the equipment.
