Taguchi Robust Design for the Stroking of a Clamping Mechanism

为保证某企业注塑机合模机构的使用性能的稳健性,提出一种将Taguchi稳健设计理论和虚拟样机技术相结合的稳健设计求解方式。详细介绍了Taguchi三次设计方法的原理和步骤;应用ADAMS建立该合模机构的参数化模型;在参数化模型基础上,通过参数设计、容差设计先后得到了最佳参数组合和噪声因素下的最佳组合。优化结果表明:该方法提高了合模过程中开合模位置的重复精度。

To ensure the performance robustness of clamping mechanism of an injection molding machine,a solving method com-bining Taguchi robust-design theory with virtual-prototyping technology was proposed. The principles and steps of Taguchi three-stage design were described in detail. ADAMS was applied to build a parametric model of the clamping units. Based on the parametric mod-el,parameter design and tolerance design were developed to obtain the best parametric combination and the best combination of noise factors respectively. The optimal results show that the repeatability of the clamping process of the mold on opening and closing position is improved through the method.
