摘要: 建立了一种基于经验的剪切阀式磁流变(MR:magnetorheological)阻尼器简化设计方法,在阻尼器磁路设计中先参考已有设计预设阻尼通道长度和修正系数,并将结构设计的基本方程与各磁场通道同时饱和原则相结合确定阻尼器结构的基本参数。分析了MR阻尼器各主要性能指标和设计参数间的关系,提出一种针对剪切阀式MR阻尼器的体积最优的3变量优化模型,并对设计的阻尼器进行了数值模拟和试验研究。结果表明,此简化设计方法简便、有效,可作为剪切阀式磁流变阻尼器工程设计的一种实用方法。Abstract: This paper presents a simplified method of designing the shearing valve type magnetorheological(MR) fluid damper based on experience. To design its magnetic circuit, it uses the existing design to preset a damping channel length in the first place; then according to the basic equation of damper structural design and the magnetic field channel saturation principle, the basic parameters of the structure of the fluid damper are determined. The paper also analyzes the relationship among the main performance parameters, designs the parameters of the MR fluid damper and puts forward a three-variable optimization model for the optimal size of the MR fluid damper. The results on comparing numerical simulation results with experimental results show that the simplified design method is simple and effective and can be used as a practical method for designing a shear valve type MR fluid damper.
