In this paper, a novel three degree of freedom configuration platform is presented based on the 2UPS/RU parallel mechanism, which serves as an end-effector for industrial robots, enhancing their workspace and flexibility in confined areas. Utilizing mechanism topology theory screw theory, we calculate degrees coupling mechanism. Additionally, inverse kinematics equations velocity Jacobian matrix are also established. The correlation between structural parameters expounded, dexterity...
Abstract In this paper, a novel special structure derived from the double-slider mechanism is presented and apply it to design of parallel mechanism, endowing designed with reconfigurable characteristics. First, comprehensive analysis motion modes carried out. By ingeniously varying slider capable three distinct obtained. This then integrated into 3UPU mechanism. As result, redesigned exhibits reconfigurability can seamlessly switch among modes. Subsequently, inverse kinematics, workspace,...
The crack propagation process in single-crystal aluminum plate (SCAP) with central cracks under tensile load was simulated by molecular dynamics method. Further, the effects of model size, length, temperature, and strain rate on strength SCAP growth were comprehensively investigated. results showed that, increase rate, plastic yield point occurred advance, limit stress decreased, deformability material increased, but temperature had less effect sensitivity SCAP. size affected deformation...
This paper reports the effects of carbon fiber-reinforced polymer (CFRP) length on failure process, pattern and crack propagation for a strengthened concrete beam with an initial notch. The experiments measuring load-bearing capacity beams various CFRP lengths have been performed, wherein opening displacements (COD) at notch are also measured. application can significantly improve capacity, modes seem different lengths. stress profiles in material around tip, end interface between then...
A new theoretical-based constitutive model has been proposed in this study to concurrently predict the ageing and coupled creep-ageing behavior both micro macro ways of aluminum alloys under complex thermal mechanical loading histories. The nucleation, growth coarsening theories for age strengthening have modified with integration dislocation-based raised by plastic or creep deformation form modelling framework. Both key microstructures (precipitates, solid solutes dislocations) properties...
This paper presents an experiment investigation on the failure behavior of a notched concrete beam reinforced with CFRP, by exploring influences length, thickness, and CFRP bonding methods ultimate bearing capacity mode. The interfacial shear stress has first been analytically derived parametric analyses are then made to predict observation finds that mode significantly depends length. brittle fracture occurs only for nonstrengthened beams; I mainly when laminate is 100 mm long; II 200...
The effects of grain boundary misorientation angle (θ) on mechanical properties and the mechanism plastic deformation Ni/Ni3Al interface under tensile loading were investigated using molecular dynamics simulations. results show that space lattice arrangement at is dependent misorientations, while interfacial energy arrangement. varies in a W pattern as increases from 0° to 90°. Specifically, first decreases then both segments 0–60° 60–90°. yield strength, elastic modulus, mean flow stress...
Short rotation woody crops (SRWCs) are key renewable feedstocks for the emerging bioeconomy. A critical step in developing a bioeconomy is defining suitable regions commercial SRWC activities. The goal of this study was to estimate obtainable yield mean annual increment and economic returns on investment Populus deltoides hybrids 33 eastern states using 3PG model (Physiological Principles Predicting Growth). Yields ranged from 0.5 11.9 oven-dry tons (ODT) ac−1yr−1 with 3.9 ODT ac−1yr−1....
Pre-stress shot peen forming is a metal process widely used in aeronautical industry. The test parts of 7150 Al alloy different thickness were pre-stress formed. deformation rule those was investigated by means changing the peening coverage. results show that radius curvature will enhance gradually with increasing plate’s thickness. In addition, enhancing coverage could raise case and parameters are unchanged. Furthermore, minimum 8mm plate after saturation reach 499mm.
As a kind of novel material high strength and light weight, carbon fiber materials have been widely used in construction industry to repair the damaged bridges improving its mechanical performance. In this work, reinforced plates made (for short CFRP) are externally bonded bottom concrete beams enhance load capacity beams. The strain energy release rates calculated at interest crack based on virtual closure technology using FEM chosen as criterion determine whether properties strengthened by...
Unified creep-ageing constitutive equations for aluminium alloy 7050 (AA7050) determined from experimental data were implemented into the finite element (FE) code, ABAQUS, through user-defined subroutine, CREEP, creep age forming (CAF) process modelling. The outer contour and yield strength of a saddle-shaped component predicted, accuracy FE prediction was analysed with results. research results show that, stress relaxation deformation occur mainly in early stage CAF process. A close...
