基于SimMechanics的飞行员操作仿真

Simulation and analysis of pilots' manipulation based on SimMechanics

利用中国男性飞行员人体尺寸和中国成年人人体测量数据,建立飞行员上肢的刚体模型.参考GJB飞机座舱布局和HB飞行品质规范要求,运用Matlab运动仿真模块SimMechannics对飞行员推杆和拉杆操作进行动力学仿真.在给定末端运动规律和负荷水平时,通过仿真可获得上肢各关节力矩,根据舒适性准则可求解上肢的三维舒适操作域.仿真结果表明负荷水平相同时推、拉杆操纵的舒适域并不相同,舒适操作范围大小与操作特征相关,在进行飞行员的工效分析和座舱的优化布局时必须根据操作特征具体分析.

According to human dimensions of chinese male pilot and the chinese manhood anthropometric data, the rigid model for the pilot＇s upper limbs was established. Referring to the requirement about cabin layout in GJB and flight quality criterion in HB, Two operation movements of the pilot, pulling and pushing stick, were simulated using SimMechannics which is a simulation module of Matlab. Analysis type is inverse dynamics. When work load and athletic rule of end effectors are given, the actual joints＇ torques could be ciphered out by simulation, and then the three-dimensional comfortable manipulation area could be acquired according to given comfort criterion. The result suggests that workload isn＇t changed, but the calculated area in the case of pushing stick is different from that of pulling stick. Therefore, there is a correlation between manipulation characters and the range of comfortable manipulation area. When dealing with pilots＇ ergonomics evaluation or optimizing cockpit layout design, It is necessary to analyze matters with an eye to manipulation characters.
