Design and verification of repair process for wind turbine blade with penetrating damage
摘要
Abstract
In order to study the repair process of wind turbine blade composite material shell with penetrating damage,a 50 m level blade was selected with artificial damage to its shell and a repair process method was de-signed.The repaired blades were subjected to full-scale fatigue tests and post fatigue static tests to verify the relia-bility of the repair process,and the impact of the repair on the blade structure was evaluated.The results indicate that for blade shells with extensive penetrating damage,it is necessary to make lining plates on the corresponding blade production molds as the repair basis to ensure that the repaired surface of the blade shell remains consistent with that before the damage;in cases where manual repair is not feasible due to limited space,the repair method of opening a window can be used;the repaired blades were subjected to fatigue tests and post fatigue static tests to ver-ify the reliability of the repair process.The experimental results indicate that the repaired blade structure has little impact.关键词
