【摘要】 针对某型采用扭杆悬架的高机动履带车辆行驶平顺性和弹性元件可靠性不高的问题,提出了扭杆油气复合悬架的新构型。建立复合悬架的弹性特性、阻尼特性的数学模型,基于Simulink、RecurDyn分别建立复合悬架的单轮及半车动力学模型,与原履带车辆开展动力学对比仿真分析。结果表明:复合悬架具备高机动履带车辆所需的非线性弹性特性,能够明显提高原履带车辆的行驶平顺性、弹性元件可靠性及悬架缓冲可靠性,具有较大的工程应用潜力。更多还原

【Abstract】 The new configuration of combined suspension with torsion bar spring and hydro-pneumatic spring is put forward,as to solve the problem that the ride comfort and elastic elements of high mobility tracked vehicle are not high.The mathematical model of combined suspension’s elastic and damping characteristics are established.Based on Simulink and RecurDyn,the single wheel and half-body dynamics model of the combined suspension are established respectively,and its dynamic simulation and analysis are carried out compared with the original tracked vehicle.The results show that the combined suspension has the nonlinear elastic characteristics required by high mobility tracked vehicle,and can obviously improve original tracked vehicle’s ride comfort,spring elements and buffer reliability.It has great potential for engineering application.更多还原
