**Title: **The Dynamic Performances Analyses of Main Clutch Servomechanism that Equips some Tracked Vehicle

**Author(s): ***Radu VilÄƒu*

**Abstract: **The working way of a system can be analyzed using the mathematical model. The mathematical models are built up based on the equations that describe the working modes of each component of the system, or the whole system as well. These are actually the variations of the output parameters as functions of the input parameters. They are graphically plotted by the typical characteristics. The mathematical model can be used to analyze the dynamic performances of the system or a proper way to improve them, as far as the actual evolution of the system is accurately enough described. As far as the validation of the mathematical model is concerned, the modeling error should be kept under tight control. Therefore, the researcher has to permanently determine the difference between either the simulated and measured output parameters. Eventually, the validated mathematical model can be used to analyze the dynamic performances of the system or a proper way to improve them, as far as the actual evolution of the system is accurately enough described. Some of dynamic charts are presented and improvements of the dynamic performances methods are given.
