Model Analysis of Offset Cylinder Based on Finite Element Method

摘要：

According to the structural characteristics of blanket cylinder in the three-point suspended independent and dependent impression mechanism in offset,the 3-D solid finite element model was established using ANSYS under hypothetical conditions by finite element model method.The intial five order model and the corresponding critical speed is gotten by the Block Lanczos characteristic value method.The calculation result shows that the maximum offset speed is less than first-order model critical speed,resonance can be avoided to meet printing quality requirements.The method is of highly significant in verifying reliability of blanket cylinder structure,forecasting response characteristic in certain circumstances in order to avoiding resonance and noise which cause mechanical defect.
