在研究中根据起落架减摆器的设计需求,通过参数化建模及有限元仿真的方法,设计了一种叶片式结构、基于磁流变效应原理的减摆器。首先根据理论公式推导出了磁流变减摆器磁路主要结构参数之间的数学关系方程组,为之后的建模和仿真提供理论支持。将此关系方程组导入利用Proe建立的参数化模型。更改参数化模型中的一个参数,将导致其他参数随之变化,从而使模型能够随着结构参数的变化而相应改变。利用ANSYSworkbench对此参数化模型进行三维仿真与优化分析,从而得到较为合理的磁路设计参数,为以后的结构定型奠定了基础。
In the research, according to the design requirements of the gear reducer, a vane structure and a damper based on the principle of magnetorheological effect were designed by means of parametric modeling and finite element simulation. First of all, based on the theoretical formula, the mathematical equations of the main structural parameters of the magnetorheological fluid damper are deduced to provide theoretical support for the subsequent modeling and simulation. Import this relational equations into a parametric model built using Proe. Changing one of the parameters in the parameterized model will cause the other parameters to change accordingly, allowing the model to change as structural parameters change. By using ANSYSworkbench, this parametric model is simulated and optimized three-dimensionally to obtain a more reasonable magnetic circuit design parameters, which lays the foundation for future structural shaping.
