摘　　要：以某中型无人战车的初期方案设计的底盘选型为研究背景,将基于完全相同的上装和车身主体的战车分别搭配履带、6×6轮式和8×8轮式3种不同的行驶系统,形成不同的设计方案,采用多体动力学仿真分析方法,计算战车在平坦路面上静止状态下和25 km/h速度行驶状态下的纵向射击的车身俯仰角和侧向射击的车身侧倾角,以及C、D和E级路面上以10、25和40 km/h速度行驶时的车身俯仰角,通过仿真对比分析3种设计方案的战车射击稳定性和行驶稳定性。研究结果表明,在不考虑制造成本、可靠性和可维修性、长途运输等因素的前提下,履带式底盘在稳定性方面更有优势,且两种轮式战车之间的差距不大。研究结果为战车在初期方案设计过程中对行驶系统的选型提供了动力学方面的参考。Taking the chassis selection of the preliminary design of a medium-sized unmanned vehicle as the research background,three different driving systems-crawler chassis,6×6 wheeled chassis and 8×8 wheeled chassis-are used for the same weapon mount system and vehicle body to form three design schemes.The firing stability and driving stability of the three design schemes were analyzed by simulating and comparing the body pitch angle for longitudinal firing and the body pitch angle for side-to-side firing under the static condition,and the body pitch angle for driving at 10 km/h,25 km/h and 40 km/h on C,D and E class roads.The results show that the tracked chassis is superior in terms of stability without considering factors such as manufacturing cost,reliability,serviceability,and long-distance transport and that there is little difference between the two wheeled combat vehicles.The results of the study provide a dynamics reference for the selection of the driving system in the initial design stage of the combat vehicle.
