牵引火炮稳态转向特性研究

对牵引火炮列车转向行驶中的稳态转向特性进行了分析和研究，建立了牵引火炮列车稳态转向的力学模型，到了表征列车转向稳定性的数学表达式，提出了对列车稳态转向特性的评价方法，认为列车的稳态转向特性是由主车稳定性因数K1决定的，只有当K1＞0时，列车才能实现稳态转向。火炮质量m2及火炮与牵引车之间的牵引距离L对K1有一定影响，在牵引火炮设计时要协调m2与L，以保证K1＞0。

A Study of Steeringstability of Towed Howitzer

The steering-stability of the train of towed howitzer is analysedin this paper. A dynamic model,the mathematic expression of steady turnability of towed howitzer and an evaluation method for turning stability are presented. It is considered that the turning stability of the train lies on the stability factor K1 of towing vehicle ,that is,only if K1 is greater than 0 the train can turn stably. The result shows that the weight of howitzer m2 and the distance L between howitzer and towing vehicle have some effects on factor K1.In designing towed howitzer,the compromise between m2 and L should be considered to keep K1 less than 0.
