摘要
某机载导弹发射装置挂弹飞行时,多次出现减振机构中防振片收起的故障现象,文中通过对减振机构的设计原理和结构尺寸链进行分析,找出问题的原因是工作斜面上的干膜润滑剂使摩擦系数变小以及防振片的预压量大,使飞机在机动飞行时易产生防振片收起从而导致减振失效。通过清除工作斜面上的干膜润滑剂并将防振片高度尺寸进行削减,解决防振片收起的问题,试验证明改进措施正确有效。
Repetitious failure occurred as the snubber uplifting in a snubbing mechanism during captive flight loading missile for a aircraft-missile launcher. Design theory for a snubbing mechanism and dimension chain were analyzed to discover the reason. It was figured out that dry film lubrication on the working incline make frictionfactor small and beforehand press dimension of snubber is larg,it make the snubbing mechanism failure of the snubber uplifting during the aeroplane maneuvering flight. Clean out dry fihn lubrication on the working incline and minify the high dimension of the snubber,it solved the question of snubber uplifting. The results of validation tests show that the measures are right ang effective.
