以HTY-8座椅为原型,建立了具有轨迹发散作用的仿真模型,通过仿真,比较分析了发散火箭在不同冲量和不同弹射条件下对弹射轨迹的影响。仿真结果表明,在零速度或速度较低的弹射条件下,采用发散火箭是必要的。在中高速弹射条件下,由于前后座椅弹射具有一定的时间差,X方向轨迹离散,前后座椅弹射轨迹发散,发散火箭的作用并不明显,尚需进一步分析人椅分离后先弹射的座椅的运动轨迹。在不利姿态弹射条件下,横滚时发散火箭作用并不明显,俯冲时则能够起到轨迹发散作用。

Knowledge representation is the core of artificial intelligence research. Knowledge representation methods include predicate logic, semantic network, computer programming language, database, mathematical model, graphics language, natural language, etc. To establish the intrinsic link between various knowledge representation methods, a unified knowledge representation model is necessary. According to ontology, system theory, and control theory, a standard model of knowledge representation that reflects the change of the objective world is proposed. The model is composed of input, processing, and output. This knowledge representation method is not a contradiction to the traditional knowledge representation method. It can express knowledge in terms of multivariate and multidimensional. It can also express process knowledge, and at the same time, it has a strong ability to solve problems. In addition, the standard model of knowledge representation provides a way to solve problems of non-precision and inconsistent knowledge.
