摘要

本文的目的是使用联合仿真方法来预测发射过程中假人的速度。以ELI公司的PL-40发射装置为研究对象，采用Adams建立了机构模型，Hypneu建立了气动模型。在10 kg假人和10 巴的油箱压力，初步的联合模拟结果与发射试验进行了比较，速度误差为-3.7%。摩擦力不是一个常数，在发射过程中很大程度上取决于航天飞机的拉力。结果与航天飞机的动力学方程和联合模拟结果一致。轮子和轨道之间的摩擦力会显著影响发射装置（LD）的假人速度。LD在发射过程中，阻力对虚拟速度的影响为0.4%。同时将联合仿真结果与所有条件下的参考结果进行了比较，最大发射速度误差为-3.8%。

Co-simulation method of pneumatic UAV launching device based on Adams-Hypneu

The purpose of this paper is to use the co-simulation method to predict the velocity of the dummy during the launching process. Taking the PL-40 launching device of ELI Company as the research target, Adams is used to establish the mechanism model, and Hypneu establishes the pneumatic model. At the launching conditions of the 10 kg dummy and 10 bar tank pressure, the preliminary co-simulation result is compared with the launching test, and the velocity error is −3.7%. The frictional force is not a constant and depends strongly on the shuttle’s pull force during the launching process. The results are coincident with the shuttle’s kinetics equations and co-simulation results. The frictional forces between wheels and rail significantly affect the dummy’s velocity of launch devices (LDs). The effect of drag force on dummy velocity is 0.4% for the LD during launching. While the co-simulation results are compared with the reference of all conditions, and the maximum launching velocity error is −3.8%.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
