Texto completoPercussive drilling is a technology that consists in applying a series of dynamic impacts leading to the rock fragmentation by two main mechanisms: crushing and chipping. These mechanisms are highly influenced by many factors on which experimental and numerical investigations were carried out in this thesis. An experimental set up was developed to carry out dynamic impact tests. Several series of tests were realized and their results were measured using a precise measurement system which was also developed during the thesis. As for the numerical work, a virtual laboratory was built based on an elasto-viscoplastic constitutive model validated on laboratory tests to describe the granite behavior and a contact mechanism to simulate the insert-rock interaction during a dynamic impact. First, several parametric studies were carried out on a homogeneous material. Secondly, a new heterogeneity modeling approach was developed to describe the distribution of minerals in the granite. These studies have provided essential elements for understanding the physical mechanisms of hard rocks destruction in percussion, for evaluating the effects of the main drilling parameters and factors and for optimizing the drilling tool

Texto completoThe recent progress in power electronics and power drives enable the development of electromechanical actuators that become attractive when price and control easiness are considered. Subsequently, they can replace hydraulic actuators in applications requiring medium efforts (few kN) and a friendly environment. On the other hand, certification and qualification, of aeronautical or automobile actuators, request performance tests covering their domain of operation. This requires high performance actuators to generate the loading efforts. The main objective of this research work is evaluating the limitation of electromechanical actuators used for force control, with respect to power performance, control and life expectancy. It is organized in order to provide advanced knowledge to test bench designers and users when high performance load simulation is required

Texto completoFriction Stir Welding (FSW) is an innovative welding process for materials with a low melting point (aluminium, copper…). It was patented in 1992 by the English organization The Welding Institute (TWI). For many years, an effort is done to reduce the investment cost for industrial applications. FSW process involves a rotating tool advancing along a path. Currently, gantry-type CNC systems are using for FSW manufacturing. These machines offer a high stiffness and can tolerate the forces during FSW in order to carry out a good weld quality. Industrials robots can reduce the investment cost; however they are not design for these applications. The main limitation is the low stiffness of the robot structure. Consequently, the robot deformation under the high process forces causes tool deviations about several millimeters. The robot path has to be compensated in order to obtain a good weld quality. The aim of this thesis is to develop a robust robotized process. The first goal is to realize a robust force control. During FSW, a constant axial forging force should be applied. Axial tool deviation is compensated with the force control approach. In this way, a modeling and identification method is done in order to design a force controller. The force controller is robust because no tuning is required, even if welding parameters or robot paths change. An experimental validation in FSW is done. The second goal is to realize a compensation of the lateral tool deviation. Unlike the axial deformation, there is no force to maintain for compensate this deviation. In industry, the lateral tool deviation could be compensated with a camera or laser sensor in order to track the weld seam path during welding. However, the cost of a seam tracking device, the aluminium reflexion and the lack of visibility in lap joint configuration are significant drawbacks. In this chapter, a compensation algorithm is designed. An elastostatic model of the robot is used to estimate in real time the deflection of the robot TCP. The compensation algorithm is coupled with the force controller defined previously. Compare with others research works about this topic, identification methods don’t need a 3D measurement system (CCD camera or laser tracker). The cost of such system is a main drawback for industrial applications. In this thesis, identification methods are easy to implement in an industrial robot and available for others processes like machining or polishing
