【摘要】 在研究基本误差前向反馈(BP)算法和模拟退火(SA)算法的基础上,提出了基于模拟退火优化的Resilient Back Propagation(RPROP)算法,并利用该算法建立了废旧聚丙烯制备板材重要工艺参数与成品板材的压制成形性能、力学性能之间的模拟及预测模型。与单纯的BP算法比较,数值计算结果表明,RPROP-SA混合优化策略具有较高的速度和精度。更多还原

【Abstract】 Based on the research of Back Propagation algorithm and Simulated Annealing algorithm,this paper proposed the Resilient Back propagation(RPROP) algorithm which is optimized by Simulated Annealing algorithm.Then,it was applied to establish the simulation and forecast model which is based on the relationship between the technological parameters of Board Preparation from Waste PP Material and the shaping property,mechanical properties of the board.Compared with single BP algorithm,the value calculation result demonstrates that RPROP-SA mixing and optimizing strategy has a higher speed and accuracy.更多还原
