摘　　要：为探究轻型高机动火箭炮在行驶过程中不平整路面对车辆悬架的影响,基于两轴连通式油气悬架,计算推导了五种不同连通形式的非线性刚度公式,并由3种不同维度下的刚度位移关系推导位移刚度特性。基于液压仿真软件AMESim,探究了不同连通形式在不同激励作用下对悬架性能的影响。以对角连通式油气悬架为例,使用Recurdyn和AMESim联合分析,对比分析了不同等级路面、不同速度的情况下,各个悬架臂输出力的变化。通过研究,直观体现了不同连接方式的特点和工作性能,可为油气悬架连通形式的适用领域提供参考。In order to explore the influence of uneven road surface on the vehicle suspension during the driving process of light high-mobility rocket launchers,the nonlinear stiffness formulas of five different connected forms of light high-mobility rocket launchers were calculated and deduced based on the two-axis connected oil and gas suspension,and the stiffness displacement relationship under three different dimensions was analyzed to obtain its displacement stiffness characteristics.Based on the hydraulic simulation software AMESim,the influence of different forms of connectivity on the performance of the suspension under different excitation actions was explored,and the diagonally connected oil and gas suspension was taken as an example,and the joint analysis of Recurdyn and AMESim was used to compare and analyze the changes of the output force of each suspension arm under different grades of road surface and different speeds.Through the summary of this study,the characteristics and working performance of different connection modes are intuitively reflected,and theoretical guidance is provided for the applicable fields of oil and gas suspension connectivity.
