Abstract Forced vibration analysis is an indispensable process for the design of a rotating component. However, rather expensive nonlinear static and linear frequency response analyses are usually accompanied by domain analysis. The traditional mode-superposition method (MSM) effectively reduces cost earlier processes remains as computational bottleneck. In this paper, application hyper-reducti...

Abstract This work focuses on transient forced vibration response characteristics of a radial turbine passing through the resonant frequency at different speeds. The structure analysis based modal superposition method is used to calculate impeller, and sweep tests are carried out verify calculation results. experimental results in good agreement with simulation impeller curve becomes steeper as...

Abstract In this paper, a self-developed solver is used to numerically simulate the isolator section under complex inlet conditions, and influence of forced panel vibration on shock flow field in conditions investigated. The results show that has certain conditions.
