Research on the simulation methodology of micro/nano wood fiber processed by nanosecond laser

设计了微纳米木纤维的形状仿真和检测系统,描述了该系统的工艺流程,并对系统中各个组件的配置和参数做了具体说明,模拟六边形细胞模型加工的木纤维仿真结果。分析了纳秒激光头的直径和微纳米木纤维切削厚度设置的影响因素,找出完全破坏细胞结构时这两个参数的最佳设置,并以柳杉为例,按此设置确定其激光束直径理论值应设置在0.008到0.016mm之间。

In this paper, we design a micro/nano wood fiber shape simulating and testing system, and describe the technology process of it. We explain the components＇ configuration and parameters of the system specifically as well as simulate wood fiber of the hexagonal cell model. Then the diameter of the nanosecond laser and the influence factors of micro/nano wood fiber cutting thickness are analyzed to find out the optimal settings of these two parameters when the cellular structure are destroyed completely and taking the Cryptomeria fortunei as an example, we determine the theoretical value of its laser beam diameter should be set between 0.008 to 0.016 mm according to this setting method.
