提出了用模态综合手段进行组合机身压力机动态特性分析的新方案。并以Ｊ５８－１６０型电动螺旋压力机为具体模型，采用双协调自由界面模态综合法对组合机身压力机进行了具体分析计算。
A new scheme to analyze the dynamic characteristics of combined body press with modal synthesis is proposed. Taking J58-160 type electric screw press as a concrete model, the combined body press was analyzed and calculated by a double coordinated free interface modal synthesis method.
