Contact rigidity of a joint is one of the main criteria of operability of forest cars. It defines vibration activity and durability of the tightened bolted connections therefore its assessment will allow to predict behavior of technical systems. In work the technique of an assessment of contact rigidity by means of the nerocomputer modeling allowing to consider parameters of quality of a blanket is presented. Results of re-searches allowed to receive mathematical models for contact rigidity. In the paper there is presented a procedure of contact rigidity estimate with the aid of neurocomputer modeling. A contact rigidity of a joint is one of the basic criteria of machine and mechanism capacity for work. It defines vibration activity and strength of tightened bolted connections therefore its estimate will allow forecasting the behavior of technical systems. Neurocomputer modeling is a promising method allowing taking into account quality parameters of a surface layer of machinery at the analysis of a deformed state.
