【摘要】 拦阻索的安全性是舰载机在航母上安全着舰的关键因素之一。针对舰载机拦阻着舰过程,提出了一种通过舰载机着舰拦阻过程中机体加速度求解拦阻索张力的方法。首先,根据舰载机拦阻钩挂索后的受载情况,确定拦阻索载荷的传力路径,实现拦阻索索力的间接识别。然后,通过考虑拦阻索的弯折波特性,对索力识别方法进行了改进和优化。最后,采用多体动力学软件MSC.ADAMS建立了离散拦阻索模型,对基于加速度的索力识别方法进行了分析和验证。分析结果显示,拦阻索索力识别的平均误差可以控制在5%以内。更多还原

【Abstract】 The safety of arresting cable is one of the key factors for carrier based aircraft’s safe landing on aircraft carrier. Aiming at the arresting and landing process of carrier based aircraft, a cable force identification method based on acceleration of carrier aircraft is proposed. Firstly, according to the dynamic relationship between the carrier aircraft and the arresting cable, the transmission path of arresting cable load is determined to realize the indirect identification of arresting cable force. Then, the cable force identification method is improved by considering the kink wave characteristics of the arresting cable. Finally, a discrete arresting cable model is established by using multi-body dynamics software MSC. ADAMS, and the acceleration based cable force identification method is analyzed and verified. The results show that the average error of arresting cable force identification can be controlled within 5%.更多还原
