摘　　要：]修理工程船的特点决定了多功能加工机床基座振动问题的重要性 ,机床产生过大的振动会直接影响机床加工精度和质量。本文基于三维空间板梁结构分析模型 ,用有限元计算了基座及其连接结构的固有频率 ,并根据计算结果提出不同的修改方案 ,以期错开结构固有频率和加工机床的工作频率。最后根据本船的实际情况选择其中一方案。For the repair boat, the vibration of the seat of the multi-function processing machine is most important. Large vibration will effect the precision and quality of the machine operation. Based on the three-dimensional beam-slab structure model, this paper calculates the inherent frequency of the seat and its connecting structure with finite element method, and proposes various modification plans according to the calculation result to differ the structure inherent frequency to processing machine working frequency. Finally, it selects one plan from the two according to this ship's situation. And the plans can be a reference for the future design.
