应用ADAMS虚拟样机软件对滑梯释放过程进行研究,分析了滑梯释放过程中滑梯包与飞机平行外开式舱门运动协调的设计技术。建立仿真模型,将滑梯释放过程中滑梯包与机身结构之间的关系考虑为接触碰撞模型,仿真过程较好地模拟了滑梯释放过程;对影响滑梯释放的参数进行仿真分析,仿真结果表明通过增长释放拉索长度或增大舱门开启速度可达到滑梯顺利释放的优化目的,并着重分析了滑梯包掉在门槛外时舱门开启速度与围布所受载荷的关系。
The ADAMS virtual prototyping software is applied to study the commercial aircraft emergency evacuation slide release process, and the motional coordination design technique of slide pack and aircraft translational open cabin door during slide release is analyzed in this paper. The simulation model of slide release is established with the restraints between slide pack and the fuselage structures which are considered as a contact-impact model. Slide release process is preferably simulated. Parameters that affect the slide release are simulated. The result shows that smoothly slide release can be achieved by lengthening release cable or increasing cabin door opening speed and the relationship between cabin door opening speed and the load on the girt when the slide pack falls outside of the sill is analyzed.
