某型航空发动机风扇增压级平衡工装采用悬臂支承结构,其支承跨距是该平衡工装的重要设计参数。针对该平衡工装的结构特点建立了最佳支承跨距的理论分析模型,给出了最佳支承跨距计算的解析表达式,并通过数值计算对最佳支承跨距进行了验证。结果表明:平衡工装最佳支承跨距的解析解与数值解一致,建立的最佳支承跨距计算方法可以为风扇增压级平衡工装的支承跨距的参数设计提供理论指导,提高平衡工装的平衡精度和平衡效果。
A type of aero-engine fan booster level balance tooling cantilever support structure, the support span is an important design parameters of the balance tool. According to the structural characteristics of the balanced tooling, the theoretical analysis model of the optimal support span is established, the analytical expression of the best support span is given, and the optimal support span is validated by numerical calculation. The results show that the analytical solution of the best span of balance tool is consistent with the numerical solution. The optimal method for calculating the span of span can provide theoretical guidance for the parameter design of the bearing span of fan supercharger, Balance accuracy and balance.
