摘　　要：针对装甲车辆综合传动装置外接油管动态特性恶化导致的失效问题,研究不同车速动态激励下的外接油管动态特性和结构强度变化规律,提出外接油管有效优化改进措施。对综合传动装置上典型外接润滑油管和供油油管系统进行动态特性分析。利用试验测试获取油管关键部位的载荷激励,进行瞬态动力学仿真和理论动力学建模,探究关键参数对油管系统动态特性的影响规律。提出动态特性的优化改进方案,油管系统关键部位的振动幅值消减15%以上。For the failure caused by the deterioration of the dynamic characteristics of external oil pipe in the integrated transmission device of armoured vehicle,the dynamic characteristics and structure strength change laws of external oil pipe under the dynamic excitation of different vehicle speeds are studied,and the effective optimization and improvement measures for the external oil pipe are proposed.The dynamic characteristics of typical external lubricating oil pipe and oil supply pipe system on the integrated transmission device are analyzed.The load excitation of key parts of the oil pipe is obtained by test.The transient dynamic simulation and theoretical dynamic modeling are conducted to study the influence of key parameters on the dynamic characteristics of oil pipe system,and an optimization and improvement scheme of the dynamic characteristics is proposed.The vibration amplitude of key parts of the oil pipe system have decreased by more than 15%.
