【Abstract】 In this paper, a gyroscopic mode synthesis technique with Lanczos reduction is suggested. Lanczos Vector and tridiagonal matrix can be computed by real number calculation in configuration space, the complex eignproblems solution and dynamics response analysis of complex largescale damped structral systems can be obtained efficiently. Research shows that, it is suitable for rotor dynamics, dynamic analysis of helicopter rotor blades fuselage systems and piping systems contained flow fluid.更多还原
