Test study of infection of rust damnification to vibration frequency for leaf of propeller

This paper shows us the test of simulation part of propeller leaf at different rust damnification condition on the electromagnetic table, and got the change rule of vibration frequency which following the ratio of damnification depth, damnification length and damnification area. The test also show us that damnification area Amacr and damnification depth Hmacr has more infection to vibration frequency of propeller leaf, the most limit depth ratio is 0.14, the most limit damnification depth of simulation part is 0.7 mm. the ratio of damnification area is 0.015, the most limit damnification area of simulation part is 3.006 mm².
