新型电流变缓冲器抗冲击特性试验研究

利用火药在密爆腔燃烧的能量产生高冲击载荷,检验所设计的电流变缓冲器抗冲击性能,并验证控制系统和控制算法的可行性。在Simulink环境中建立电流变缓冲系统模型,并对控制算法进行了仿真分析。对不同固定电压加载阻尼力、不同控制加载方式及控制策略性能进行了分析比较。结果表明:模糊控制能够很好地达到缓冲系统提出的控制要求,具有最优的减振控制效果。研究结果为优化电流变缓冲器结构设计及其系统控制算法提供参考。

Theoretical Study and Structural Design of ERF Shock Absorbers

Electrorheologica (ER) technique is a developing technology. In a wide range of engineering applications of ER fluid, shock absorbers employing ER fluids, whose damping force can be controlled continuously and promptly through electric signals, is one of the most prospective applications of ER fluid. In this paper, the theoretical midel and method to predict the damping force of ERF shock absorbers are established.
