Thin-walled workpieces frequently appear to chatter during milling, causing the creation of vibration patterns on surface workpiece, which affects machining quality and workpiece performance. Identification online is important for thin-walled parts. The signal associated with changes dynamically throughout milling process due in tool position, removal material, transmission-related attenuation characteristics, making reliable identification difficult. This research proposes a unique approach...
Due to the synthetic effect of hydraulic force and magnetic force, chains in magnetorheological fluid (MRF) squeeze mode appear bending even fracture, especially latter which has a potential influence on macroscopic yield MRF. Thus fracture mechanism is investigated. As an important factor leading fractrue, between particles modelled. Based model, criterion established that when horizontal component turns zero, fractrue phenomenon happens. this criterion, angle position are analyzed. At...
Magnetorheological fluid is a novel functional material, of which quasistatic squeeze behavior needs to be quantitatively controlled in industrial applications. Since the has close relation with microstructure variations, thus it modeled from microscopic approach. By analyzing compression single chains, aggregation chains BCT structure and structure, initial stress [Formula: see text], yield strain post-yield stage text] are respectively modeled. It found that they have an exponential...
A shallow spherical shell is a typical weak-stiffness aerospace structure, which always expected to have less or no deformation in machining. To control the deformation, magnetorheological fluid (MRF) introduced support since it has high controllability with help of external magnetic field. minimize adopted MRF should be determined according varying loads, but optimal not been designed and modeled. In this paper, generate field controllable strength/region, an array-type device...
A flexible supporting configuration based on magnetorheological (MR) effect for thin-walled part was designed. In this configuration, two crucial issues need to be concerned. One the force needed support thin-wall efficiently when fluid (MRF) solidified in certain magnetic field, other layout method of magnet array arrange field reasonably. Firstly, relationship MRF elastic modulus and induction intensity obtained experimentally. And then, distribution exciting analyzed numerically, which...
Magnetic source configuration plays an important role in flexible fixturing based on magnetorheological fluid (MRF). In this article, a novel magnetic connected to spindle of machine tool is designed generate specific field machining region. The can follow trajectory real time, solidifying under current region and constituting mirror support axial milling force. makes work squeeze mode, thus providing stronger supporting capability the same field. has self-cooling function, permitting very...
