摘要
CDC减振器是一种通过对控制阀输入不同的控制电流实现阻尼力连续可变的新型减振器。在研究CDC减振器结构和工作原理的基础上,利用CATIA V5建立某CDC减振器的三维实体模模型,采用ICEM-CFD建立流场模型并进行网格划分,利用ANSYS FLUENT软件,分析求解低速复原行程的CDC减振器仿真模型,得到低速工况下的活塞与复原阀片的压力云图以及控制电流与复原阻尼力关系,将仿真结果与CDC减振器试件的外特性试验结果比对,验证CDC减振器低速复原行程流体仿真模型的正确性。
CDC damper is a new type of dampers which can achieve the continuous variable damping farce by inputting different control current to control valve. Based on researching the CDC damper structure and working principle, CATIA V5 is used to build a three-dimensional solid model of one kind of CDC dampers. ICEM-CFD is used to establish the fluid model and generate mesh. ANSYS FLUENT software is used to analyze and solve the CDC damper simulation model in low-speed rebounding stroke, then pressure nephogram of piston and rebounding valve and the relationship between control current and rebound damping force are got. The correctness of the CDC damper fluid simulation model in low-speed rebounding stroke is verified by comparing the simulation resets with external characteristics test results of CDC damper specimen.
