本文对美国贝尔直升机公司在主减速器与机身的独特连接形式——波节梁(或叫节点梁)进行结构和受力分析,并通过两种同一型号直升机(贝尔212和贝尔214ST)振动对比试飞所获得的曲线,说明波节梁是一种降低直升机振动的有效措施。
In this paper, the structure and force analysis of Bell-Beam (or called node beam), which is the unique form of connection between the main reducer and the fuselage, is analyzed by Bell Helicopter Co., Ltd. and vibrated by two helicopters of the same type (Bell 212 and Bell 214ST) Contrast the curves obtained by test flight, indicating that the knot beam is an effective measure to reduce the helicopter vibration.
