前襟操纵拉杆开裂分析及改进措施

Cracking Analysis and Improvement Measures of Front Flap Pull Rod

通过普查和典型件分析，查明了拉杆开裂是结构设计不当、制造未达到要求、装配预紧力控制不严及服役期间条件较差造成的。据此，在设计和生产中采取了改进措施。

By general investigation and typical piece analysis, the unsuitable structure design, manufacture not meeting requirement, assembly pretightening force not controlled strictly, and bad service condition are found to give rise to the crack of pull rod. Corrections have been made in design and production.
