复合材料缠绕压力容器缠绕过程模拟

The simulation of winding process of filament wound pressure vessel

为了提高复合材料缠绕压力容器缠绕工艺效率及优化缠绕过程,研究并设计了复合材料缠绕压力容器缠绕过程的模拟软件.模拟软件主要包括两个模块:缠绕设计模块和模拟模块.模拟模块中,通过在几何空间和色彩空间,描述纤维缠绕压力容器成型工艺的芯模、落纱点、悬纱、丝头的运动规律和运动轨迹,形成动态画面,直观地反映出缠绕过程中落纱、纱线排布、悬纱、芯模和丝头运动以及线形变化,显示出纤维缠绕成型的全部过程.该模拟软件的建立,有利于加深对复合材料缠绕压力容器缠绕工艺过程的理解.

A simulative software for the process of fiber wound reinforced plastics was introduced to improve the efficiency and optimize the process. The software was produced by researching the law of fiber wound rein- forced plastics. There are two main modules in this simulative software： the winding design module and the simulate module. In the simulate module, the software includes the description of the mandrel, the fiber-tou- ched point, the suspend-fiber, the kinematics track and the law of delivery point using geometry and color in- struments, and then form dynamics screen. So, it can reflect fiber-touching, arrange of fiber, suspend-fiber, kinematics of mandrel and delivery point, and the variety of line type during winding process intuitionally. And show the entire procedure of filament wound molding. This software is useful for understanding the process of fiber wound reinforced plastics.
