摘　　要：深入分析了国内外一维弹道阻尼修正机构优缺点,优化设计了一种新型可控阻力系数的一维阻尼机构;通过对该机构进行气动特性模拟和修正能力计算,验证机构平均增阻系数达到2.677 5,其修正能力强;阻尼片能随意展开指定大小,便于实现多次修正。This paper in-depth analyzed the basis of the one-dimensional trajectory correction advantages and disadvantages both at home and abroad,and a flexible and variable drag coefficient of correction mechanism was optimized and designed,and mechanism of the aerodynamic characteristics and correction ability was verified by simulation. This mechanism gained an average resistance coefficient to 2. 677 5 and correction ability is better. Damping can be arbitrarily specified size,which makes the multiple corrections be realized.

关 键 词：阻尼机构 可控阻力系数 多次修正
