摘要:

针对摩托车油箱外壳成形缺陷,采用Dynaform软件对油箱外壳双片组合成形(Double-Cover Forming,DCF)过程进行了数值仿真分析,仿真结果表明侧壁起皱和局部破裂是主要缺陷。利用数值模拟与正交试验设计(Orthogonal Experimental Design,OED)相结合的方法分析和优化了拉延筋高度和压边力参数,分析表明适当增大拉延筋高度和压边力可有效抑制起皱缺陷。采用优化后的参数进行制件压延成形试验,结果表明制件成形均匀性有了较大改善,成形质量得到提高。

For the drawing defects of the motorcycle fuel tank cover, the forming process of Double-Cover Forming (DCF) was simulated by Dynaform software, and the results show that sidewall wrinkling and local rupture are main defects. Two forming parameters of draw- bead height and blank holding force were analyzed and optimized by combining numerical simulation with Orthogonal Experiment Design (OED), and the analysis results indicate that it is effective to suppress the wrinkling defects by increasing the above two parameters properly. The part is formed with optimized parameters, and the results show that the overall forming uniformity is improved considerably. Therefore, forming quality is enhanced.
