FIELD: helicopter industry. ^ SUBSTANCE: method includes increasing the natural vibration frequency of members to exceed the blade frequency of helicopter vibration by determining conventional weights of members to be damped, KG and (K-1)G, where K>=1.8, G is the actual weight of the member. The values of conventional weights determine the size of bottom and top dampers. When assembling, the top dampers are preliminary compressed to provide increasing the resonance frequency. ^ EFFECT: simplified method. ^ 2 cl, 3 dwg, 2 tbl |
