摘要

针对双轨火箭滑橇动力试验中制动失效、液压制动解体、滑橇体和制动严重变形等问题，提出了水阻力分析方法。利用液压制动阻力和动力方程建立了计算方程，并利用水阻力计算公式对制动距离进行了二次估计。估计结果与实测结果一致。验证了制动距离计算方程的正确性。通过增大滑车的滑行距离，减小滑车进入水中的速度和分段来减小制动力。设计了高速双轨火箭滑车的水制动方案。可指导双轨火箭滑橇动态试验。

Design of Brake Scheme of Double Track Sled Rocket sled

The method of water resistance was gained aiming to brake failure, hydraulic brake disintegration, sled body and brake serious deformation in double-track rocket sled dynamic test. The calculation equations were gained with hydraulic brake drag force and dynamic equation and braking distance was estimated twice with calculation formula of water resistance. The estimation results were consistent with the measured results. The correctness of the calculation equation of braking distance was verified. By increasing the sliding distance, reducing the velocity and segmented of rocket sled into water reduced brake force. The water brake plans of high speed double-track rocket sled are designed. That could guide double-track rocket sled dynamic test.
