Force control system is used in robots with different types of application. Force control systems are used in operations that there are not enough vision data and may be including unforeseen manipulator errors. In this machine, motion speed of end effector is being changed by certain rate of contact force in software. In this paper, at first manipulator operation and end effector of robotic pruning machine with force control system are described. Then the effect of sensitivity coefficient of force control system, rotating speed of cutting tool, diameter of wood bar and separate and interface effects of them on cutting time and power consumption are analyzed by Duncan’s test. Finally, with investigation of comparison means and results of analysis of variance, the effect of force control system on time and power consumption, and method of suitable usage of the force control system in robotic pruning machine are investigated.<\div>

In this research the finite element method (FEM) is applied to analyze the composite drillstring vibration. The capability of the developed computational scheme for dynamic response calculations has been investigated in comparison with the steel drillstring. Comparisons are made wherever possible with other recorded results available in the literature<\div>

Lack of understanding of the dynamic behavior of drillstring is the major factor of drillstring failure and wells destruction,that financial losses and a lot of time on the project will impose. Commercial software dedicated to the drillstring to the string's natural frequencies are calculated and could not provide dynamic analysis. Therefore in this research with the aid of modeling ADAMS software to analyze the dynamic behavior of the drillstring,first the design of a drillstring in the Solidworks software according to the standard model and its various components are carried out,then the designed model imported in ADAMS software,in this phase the important parameters and their influences are considered. Comparisons are made wherever possible with recorded results available in the literature. Modeling and analysis has shown the validity of the proposed model.<\div>
