摘　　要：针对目前我国机载导弹普遍采用的冷弹射和热弹射发射的缺陷,提出了一种利用EHA(电静液作动器)压缩弹簧来蓄能的新型弹射方案;利用动力学仿真软件ADAMS对其弹射机构性能影响因素进行分析;结果表明,当弹射行程在120~170 mm,弹射杆直径为50 mm或60 mm,弹射间隙小于30 mm,悬挂物质量小于200 kg时,此弹射装置可以满足悬挂物分离的技术要求。该研究与论证工作对于机载弹簧蓄能弹射装置的设计与优化有着较大的参考价值。Aiming at the shortcomings of cold and hot ejection launching commonly used in airborne missiles in our country,a new ejection scheme using EHA(electro-hydrostatic actuator)compression spring to store energy was proposed.On this basis,the factors affecting the performance of ejection mechanism were analyzed by using dynamic simulation software ADAMS.The results show that when the ejection range is between 120 mm and 170 mm,the diameter of ejection rod was increased.When the ejection clearance is less than 30 mm and the suspension mass is less than 200 kg,the ejection device can meet the technical requirements of suspension separation.This research and demonstration work has great reference value for the design and optimization of the airborne spring energy storage ejection device.
