| 摘要: |
| 为了探究战场威胁下多轴特种车辆轮胎系统的生存概率,对轮胎系统的抗毁伤能力进行量化表征,提出了一种基于等毁线的轮胎系统抗毁伤能力表征方法。针对轮胎毁伤状态下对整车的影响,基于车辆动力学对轮胎系统的力学特性进行量化表征,建立了轮胎系统功能毁伤的计算模型；采用毁伤理论对冲击波超压场进行弹目交会和量化分析,建立了轮胎系统物理毁伤的计算模型；根据爆心与车辆的位置关系,采用面向车辆全面域的计算特征线,建立了轮胎系统等毁线计算模型。以某型五轴特种车辆为例,进行了表征方法验证。研究结果表明:该表征方法可应用于战场威胁下多轴特种车辆轮胎系统的抗毁伤能力表征,为后续机动规避和防护能力提升奠定模型基础。 |

| Abstract: |
| In order to explore the survival probability of multi-axle special vehicle tire system under battlefield threat and quantitatively characterize the anti-damage capability of tire system, a new method based on isodamage curves was proposed to characterize the battlefield anti-damage capability of the tire system. Aiming at the influence of tire damage on the whole vehicle, the mechanical characteristics of tire system were quantitatively characterized based on vehicle dynamics, and the calculation model of tire system functional damage was established. Based on the damage theory, the collision and quantitative analysis of shock wave overpressure field were carried out, and the calculation model of tire system physical damage was established. According to the position relationship between the burst core and the vehicle, the calculation model of the tire system isometric line was established by using the characteristic line for the vehicle in the whole area. A five-axle special vehicle was taken as an example to verify the characterization method. Results show that this characterization method can be applied to the characterization of the anti-damage capability of the multi-axle special vehicle tire system under battlefield threat, which lays a model foundation for the improvement of maneuvering avoidance and protection ability in the future. |
