摘　　要：为满足轮式装甲车辆对高机动越野性能的要求,提出了将滚珠丝杠惯容器与双筒式油气弹簧集成的技术方案,构建了惯容式油气悬架装置。通过剖析该悬架装置弹性力、阻尼力和惯性力的产生机理,揭示了各参数之间的耦合关系,提取出3个相互独立的关键结构参数,采用正交试验法,结合惯容式悬架系统非线性动力学仿真,确定了上述3个关键结构参数的最优值。力学特性试验和1/4悬架试验的结果表明,与传统油气悬架相比,采用惯容式悬架使车体振动加速度降低了13.89%,大幅提高了车辆的乘坐舒适性。For meeting the requirements of wheeled armored vehicle on high mobility and cross country performance,a technical scheme of integrating ball screw inerter and double cylinder oil-gas spring is proposed to construct an inerter-oil-gas suspension device.By analyzing the generation mechanism of elastic force,damping force and inertia force in that suspension device,the coupling relationship between parameters are revealed,with three independent key structural parameters extracted.By adopting orthogonal experiment method,combined with nonlinear dynamic simulation on inerter-based suspension system,the optimal values of three key structural parameters mentioned above are determined.The results of mechanical characteristics test and 1/4 suspension test show that compared with traditional oil-gas suspension,the vibration acceleration of the vehicle body with inerter-based suspension reduces by 13.89%,greatly enhancing the ride comfort of vehicle.
