摘要
针对磁流变减振器示功特性出现畸形的问题,首先采用Hypermesh软件建立磁流变减振器的液体模型和固体模型,将模型导入ADIAN液固耦合软件并建立流固耦合模型,并通过减振器台架示功特性试验验证了流固耦合模型的正确性;采用该流固耦合模型分析了不同速度、不同磁场及不同氮气压力下的内部速度分布和压力分布,通过对不同氮气室压力的减振器内部压力场仿真,合理选择了磁流变减振器内的氮气压力,避免了减振器示功特性出现畸形。这一磁流变减振器特性分析方法为避免磁流变减振器示功特性出现畸形提供了理论依据。
In order to solve the problem of abnormal force-displacement characteristics of magneto-rheological(MR) damper, firstly, the fluid model and solid model of MR damper were established by Hyper mesh software, the model was imported into ADINA fluid-solid coupling software to establish the fluid-solid coupling model, and the correctness of the fluid-solid coupling model was verified by the bench test of the force-displacement characteristics of the damper. The fluid-solid coupling model was used to analyze the internal velocity distribution and pressure distribution under different velocity, magnetic field and nitrogen pressure. Through the simulation of the internal pressure field of the MR damper with different nitrogen chamber pressure, the nitrogen pressure in the MR damper was reasonably selected to avoid the deformity of the force-displacement characteristics of the MR damper. The characteristic analysis method of MR damper studied in this paper provides a theoretical basis for avoiding the deformity of the force-displacement characteristic of MR damper.
