| Abstract: | A brief introduction was given to the rocket ejection seat connected on the head lug fracture failure, installation position and role the main factors, such as raw material, size, production process, fracture surface, design and working condition, which may lead to the failure of the connecting lugs are systematically investigated, analyzed and verified. The failure mechanism of the parts was identified and accurate positioning. By effective verification, it would play a positive guidance and reference significance for the design and application of aeronautic products to improve fatigue resistance. |
