摘要: 短距离起飞产生的过载加速度可能对飞行员的安全操作造成极大隐患。本文建立飞行员-座舱系统的多刚体模型,仿真分析了胸-背方向的加速度载荷(Gx)对飞行员驾驶状态下的人机动力学响应。首先,根据第3百分位的男性人体测量学数据,通过三维CAD软件建立了飞行员的虚拟假人模型;并根据设计参数的要求建立了包括座椅和操作杆(油门杆与驾驶杆)在内的飞机座舱模型。然后,以标准的短距离起飞的加速度模拟曲线为载荷条件,利用多刚体动力学软件ADAMS模拟了飞行员在短距离加速起飞过程中的动力学响应及飞行员与操作系统之间的力学相互关系。仿真结果表明,过载加速度会经飞行员身体传递给操作杆,5G加速度载荷产生的传递力作用在驾驶杆和油门杆上的值分别为128 N和211 N,两者均已超过了通常操作杆所设计的有效阈值,因此存在误操作的可能。另外,本文结合仿真结果和国外现有战机设计,提出了短距离起飞下飞行员避免误操作的可行方式,结果显示该方式可以有效地转移加速度传递所带来的影响。本文方法将为在短距离起飞作用下避免误操作的分析提供技术途径,得到的结果将为驾驶部位的人机设计提供参考。

Abstract: Acceleration overlord during short-distance takeoff might affect the operation performance of pilot. To avoid potential risks, a pilot-cockpit multi-rigid-body model was established to simulate the man-machine dynamic response under chest-to-back (Gx) acceleration loads. Firstly, using 3D CAD software, the multi-body pilot dummy was established according to the 3% male body measurement data. Also, the cockpit model including human-seat and control system (throttle stick and steering axle) was established according to the design parameters. The dynamic response between pilot and control sticks under a standard simulated Gx acceleration curve is simulated using the multibody dynamics simulation software ADAMS. The simulation result shows that the overload acceleration can transmit through the human body to the sticks. The transmission force generated by 5G acceleration acting on the steering axle and throttle stick are 128 N and 211 N, both of which have exceeded the designed effective force threshold, leading to a potential risk of misoperation. Further, considering the simulation results and the existing foreign fighter design, we proposed an effective posture for the pilot to avoid misoperation, which was validated by the simulation in this paper. In conclusion, the proposed method provides an effective technology to avoid the misoperation in short-distance takeoff. The results would give a reference for the man-machine safety design.
