Operation-condition transfer path analysis method based on Landweber iteration method

The invention discloses an operation-condition transfer path analysis method based on a Landweber iteration method. Based on test operation condition designing and test operation condition data measurement, a transmissibility functional matrix is reversely solved through observed reference-point response signals and target-point response signals. The operation-condition transfer path analysis method includes the following steps that 1, reference-point and target-point response signals under a test condition are collected by arranging sensors, and observed signals are subjected to fast fouriertransform; 2, an iteration scheme suitable for the ill-posed Landseber iteration method is selected and used for estimating the transmissibility functional matrix; 3, the obtained transmissibility functional matrix is reciprocally multiplied by reference point responses measured in actual conditions, and the contribution quantity and the total contribution quantity of all transfer paths are calculated. According to the op
