基于有限元和Modelica的柔性梁振动控制仿真

Vibration Control Simulation for a Flexible Beam Based on FEM and Modelica

柔性梁在快速定位过程中容易产生长时间的瞬态振动而影响定位速度和精确度。采用有限元法和Modelica语言对非理想柔性悬臂梁的振动控制问题进行了计算机仿真研究。采用的仿真方法具有建模工作量小 ,重用性好的特点。

Flexible beams can have a long transient vibration when positioned quickly, which is harmful to their positioning speed and accurate tracking ability.A study on the simulation of vibration control problem of a non-ideal overhung flexible beam by a new method based on the finite element method(FEM) and Modelica language is introduced. This method can reduce the modeling difficulties and make the model much more reusable. Simulation results show the effectiveness of the new method.
