The subject of the research is an opportunity to increase the efficiency of vibration diagnostics of hoisting cranes through the use of simulation of the vibration signal. In the article the basic approaches developed by the authors to construction of the type diagram of a mechanism and modeling of a vibrating signal of the crane mechanism with operational defects are resulted. The basic design dependences for the description of a vibrating signal of the mechanism with defects at presence of amplitude and frequency modulation are obtained, approaches to modelling of stages of acceleration and braking of the mechanism are formulated, the technique of modelling of a noise component of a signal is identified. The possible areas of application of simulation modeling during vibration diagnostics are shown and a brief description of the results obtained is given. Pre-imitation modeling will improve the detection of defects during the vibration diagnostics of cranes and reduce the time spent on the analysis of the obtained results.
