摘要: 建立了空气弹簧等效模型、线性模型与非线性模型, 分析了3种模型对车辆直线平稳性和曲线通过安全性的影响。研究结果表明: 在计算车辆直线垂向平稳性时, 空气弹簧等效模型计算精度较差, 而空气弹簧线性模型和非线性模型计算精度较高; 由于空气弹簧线性模型比非线性模型简单, 建议在计算直线垂向平稳性时优先采用空气弹簧线性模型; 在计算车辆曲线通过安全性时, 空气弹簧非线性模型能反映空气弹簧的充排气特性, 计算精度较高; 由于模型自身的局限性, 空气弹簧线性模型和等效模型无法反映空气弹簧的充排气特性, 计算精度较差, 因此, 建议在计算曲线通过安全性时采用空气弹簧非线性模型。Abstract: The equivalent model, linear model and nonlinear model of air spring were established, and the influences of three models on the ride comfort of straight track and the safety of curve track were studied. Analysis result shows that the accuracy of equivalent model is smaller for the calculation of ride comfort of straight track, but the linear model and the nonlinear model can provide better accuracy. The linear model is simpler than the nonlinear model, therefore, the linear model is suggested to be adapted for the calculation of ride comfort of straight track. Since the nonlinear model of air spring can reflect the dynamic performance of air spring and provide better accuracy compared with the linear model and the equivalent model, therefore, the nonlinear model is recommended to be used in the safety calculation of curve negotiation.
