Abstract

Abstract A new inverse kinematic-optical-thermal (IKOT) model is introduced to control the process temperature in laser assisted tape winding and placement processes. The optimum time-dependent laser power distribution is obtained by employing a grid of independent laser cells while keeping the temperature of substrate and tape at the target temperature. Multi-layer cylindrical hoop winding with laser grids of 1 × 1, 28 × 1, and 28 × 11 and helical winding of a pressure vessel with laser grids of 22 × 1 and 22 × 11 are considered. It is found that the optimized laser power distribution pattern remains the same during the consecutive hoop winding process while the total power reduces to compensate the heat accumulation. A more non-uniform laser power distribution is obtained for the helical winding because the substrate curvature changes drastically at the dome section of the pressure vessel. The change in the optimum total laser power is found to be almost constant for the helical winding case. Finally, the IKOT model is evaluated by analyzing the effect of the computational parameters on the optimized process temperature. Graphical abstract

基于逆运动学-光学-热模型的激光辅助卷绕工艺优化

摘要提出了一种新的逆运动学-光-热(iot)模型，用于控制激光辅助胶带缠绕和贴装过程中的工艺温度。在保持衬底和带的温度为目标温度的情况下，采用由独立激光单元组成的网格，获得了最佳的随时间变化的激光功率分布。考虑了激光网格为1 × 1、28 × 1和28 × 11的多层圆柱环形缠绕和激光网格为22 × 1和22 × 11的压力容器螺旋缠绕。结果表明，在连续绕圈过程中，优化后的激光功率分布模式保持不变，但总功率减小以补偿热积累。螺旋缠绕时，由于压力容器圆顶处衬底曲率的剧烈变化，使得激光功率分布更加不均匀。发现在螺旋缠绕情况下，最佳总激光功率的变化几乎是恒定的。最后，通过分析计算参数对优化后工艺温度的影响，对iot模型进行了评价。图形抽象
