摘　　要：针对非高斯随机路面条件开展了八轮重型装甲车辆悬架的减振控制策略研究。当前随机路面通常采用基于功率谱密度法的高斯信号进行表征,难以准确描述装甲车辆行驶的复杂路面工况。建立了八轮重型装甲车的整车悬架模型,实现了对起伏路面非高斯性能的准确表征,提出了针对非高斯随机路面的模糊自适应悬架振动控制策略。仿真结果表明:所提出的控制策略可在装甲车所行驶的实际路面工况下对整车起到良好的减振效果,为八轮装甲车辆的减振控制奠定了理论基础。In this paper,the damping control strategy of eight-wheel heavy armored vehicle suspension was studied under non-Gaussian random road conditions.At present,the random road is usually characterized by Gaussian signal based on power spectral density method,which is difficult to exactly describe the complex road conditions of armored vehicles.First,the suspension model of the eight-wheel heavy armored vehicle was established;Second,the accurate characterization of non-Gaussian performance of undulating road was realized;Finally,a fuzzy adaptive suspension vibration control strategy on non-Gaussian random roads was proposed.The simulation results show that the proposed control strategy has a good damping effect on the armored vehicle under the actual road conditions,and lays a theoretical foundation for the damping control of the armored vehicle.
