基于动态灵敏度分析的版辊磨床床身结构参数修改

Modification of Design Parameters for the Printing Roller Grinding Machine Bed Based on Dynamic Sensitivity Analysis

以床身的模态频率的大小作为衡量结构动态特性优劣的性能指标,通过对版辊磨床床身的有限元参数化建模,进行了床身参数对床身动态特性的灵敏度分析。在分析结果的指导下,对床身设计参数进行了修改,获得了具有良好动态性能的床身结构。

The values of the model frequencies for the printing roller machine bed are defined as the target to examine the dynamic performance of the structure. Based on parameterized finite element model of the bed, the sensitivity of the structure parameters for the bed to the dynamic performance are carefully analyzed. According to the results of computotions, the design parameters of the bed are modified and the good performance for the machine bed is obtained.
