Analysis for the damage of track switch rocking arm in one launcher and the improved methods

The rocking arm of the lower rail track switch was broken during one test of certain type of launcher.In aim to this problem,the careful analysis was carried out and the design deficiencies were found out.Thus,the interlock protection can be realized for the equipment in special operating position by increasing proper amount of position signal transmitters and collecting operating condition signals of spring-loaded rocking arm system.Additionally,the man-machine operating interface of the launcher can be improved by providing condition display signals and acoustic and optic warning signals for the spring-loaded rocking arm system in special operating position.
