对一种四杆机构展开机构进行了成功的失效分析。分析了材料热膨胀系数失配、铰链摩擦过大、限位开关干扰、温度梯度引起的阻性预紧力等可能的失效原因。描述了最终结论和采取的纠正措施。最后，讨论了在调查过程中吸取的宝贵经验教训。
A successful failure investigation of a four-bar linkage deployment mechanism has been performed. Possible failure causes such as the mismatch of material coefficient of thermal expansion (CTE), excessive hinge friction, limit switch interference, and thermal gradient induced resistive preload were investigated and are discussed. The final conclusions and corrective actions taken are described. Finally, valuable lessons learned during the investigation are discussed.
