Özet:

In this study, the dynamic modeling of a single-cylindrical four-time diesel engine's piston, biel, sick and block examined the rotative angle speed changes of the sick mill and the bloc vibrations. The created dynamic model has four freedom degrees and consists of the angle movement of the sick mill, the angle movement around the sick mill axis of the bloc, the linear movements in the downward and horizontal directions of the bloc.The analysis used the experimentally obtained gas pressure profiles for four different motor loads. Changes in angle speed have been observed by the engine load. It has been determined that the angle vibrations around the sick mill axis are caused by the gas forces, the linear vibrations in the downward and horizontal directions are caused by the isepiston mass and the imbalance of the sick mill. The balance weights used to reduce the vibration from the mass atalets of the piston have been found to increase the vibration in the horizontal axis. This is why it is necessary to use the balanced weights that will decrease the weight to half instead of re-seting the vibration width in the river axis. From the tacho strengths obtained depending on frequency; the optimal values of the tacho's foam and deforestation stages are determined by 100 kN/m and 1000 Ns/mol respectively.
