摘　　要：以电子词典下盖为例,运用数值模拟技术,通过Moldflow流动分析,对注塑工艺参数影响ABS制品沉降斑进行了敏感性分析。引入敏感度因子来衡量各项工艺参数的独立作用对沉降斑的敏感程度,从而确定影响制品沉降斑的主次因素。结果表明,保压压力、熔体温度和注射时间是影响ABS制品沉降斑的主要工艺参数,而模具温度和保压时间为次要参数。根据参数水平影响趋势图,分析得出最优组合方案,并对该方案进行了模拟验证。The sensitivity analysis of injection process parameters which influenced the sink marks of ABS injection parts in electronic dictionary lower cover was performed using numerical simulation technology based on Moldflow analysis.A sensitivity factor was introduced to evaluate the sensitive degree of every process parameter on the sink marks,in order to find the principal and secondary determining parameters on the sensitivity degree.The results showed that influence of the packing pressure,melt temperature and injection time on the sink marks of the ABS product were comparatively higher than that of the mold temperature and packing time.Through analyzing the diagrams of influential factors,the optimized process parameter scheme was obtained and further verified by simulation test.
