Every mesh bar is modeled by a linear bar clement. The lumped mass point is set at the ends of each element. The net can be simulated by a discretized model consisting of many point masses and elements without mass. 3D shapes and the distribution of tensions of the net at different moments can be found from time integration of a set of motion equations with a computer program. Two nets are simulated according to reference experiments. Calculated results are in accordance with experimental results. The method is applicable and can be applied to improving design of, and research into other flexible structures, such as net cages.展开更多

Using bioenergy effectively and setting up a perfect bioenergy industry chain are the premises for bioenergy to be well developed. The main applications of bioenergy in China are electric power generating and fuel refining. But there is still some gap between Chinaand other countries in bioenergy’s development, not only in the technology, but also in government policy support. First of all, this paper briefly introduces the concept and the basic condition, the development and utilization of bioenergy inChina. Secondly, this paper makes an analysis and comparison of supply chain for the biomass and coal. Finally, this paper gives some suggestions to the further research orientation of the biomass supply chain based on its characteristics.展开更多
