军用履带车辆越野平均速度预测模型研究

Research on Prediction Model of Average Cross-Country Speed of Military Tracked Vehicle

建立军用履带车辆越野平均速度预测模型,为越野平均速度这一综合指标论证提供量化分析方法。模型采用动态预测法将行驶路线划分为若干典型路面,根据各路面对车辆速度的主要制约因素,综合运用牵引计算模型、冲击振动模型以及转向临界速度模型等动态计算速度变化过程,进而得到越野平均速度。应用该模型对某型履带车辆越野平均速度进行了分析,结果表明:该模型能全面反映影响越野平均速度的多种因素,可为履带装甲车辆机动性分析提供综合性的量化手段支持。

An integrative matchematical prediction model on the average cross-country speed of military tracked vehicle was presented in order to provide quantification analyzing method for demonstrading average cross-country speed as an integrated index. The prediction model is based on calculation of velocity variation, in which the maneuver route is divided into several uniform terrain units of ground character and the speed variation of vehicle across every unit is dynamically calculated according to the main factor of the unit through acceleration model, ride dynamical model and swerve limitation model and etc. The average cross-country speed for a certain type tracked armored vehicle was analyzed by the model. The analyzed results show that the model can fully reflect the influences of multi-factors on average crosscountry speed and provide an integrated and quantification method for military tracked vehicle mobility analysis.
