In its working process, a high-speed motorized spindle bearing-rotor system is affected by variety of vibration excitations, which severely affect the machining precision and reliability. view problems in active control current smart-material-based systems based on structural layout piezoelectric device controlled system, bearing was directly connected to actuator via sleeve, improved efficiency stack actuator. Furthermore, improve robustness system’s performance under different external...
The motorized spindle is the core component of CNC machine tools, and vibration it reduces machining precision service life tools. Owing to fast response, large output force, displacement piezoelectric stack, often used as actuator in active control spindle. A self-sensing (SSA) can reduce cost system simplify structure by eliminating use a sensor, because SSA have both actuating sensing functions at same time. signal separation method based on bridge circuit widely applied its simple...
With the development of global economy, demand for manufacturing is increasing. Accordingly, human–robot collaborative assembly has become a research hotspot. This paper aims to solve efficiency problems inherent in traditional human-machine collaboration. Based on eye–hand and finite state machines, method proposed. The determines human’s intention by collecting posture eye data, which can control robot grasp an object, move it, perform co-assembly. robot’s automatic path planning based...
Mitigating collision is a fundamental issue in contact problems, and required to ensure the safety of robotic cell. Research into problem between robots their environment divided two parts: one uses environmental model parameter estimation, other robot force control method. There are main problems with this research One that levels not effectively combined form complete solution for practice. The on excessive phase has been studied depth control. In paper, sensing-executing bionic system...
Hydraulic vibration exciter (HVE) is an important basic equipment for modern industrial production and scientific experiments. However, when HVE working, the inevitable alternating pressure in its hydraulic system could give rise to unreliable work of pilot-operated relief valve (PRV). The present paper aims determine abnormal opening mechanism PRV under pressure. In this work, a mathematical model was presented validated, essential reason discovered. influence characteristic parameters on...
Conventionally, the influence of guy wire and wind load on derrick was often ignored in static strength analysis truck-mounted workover rig, it does not accord with actual working conditions. This paper made finite element for one Truck-mounted rig through ABAQUS software. The author derive maximum hock which can bear, reasonably shorten projective radius wire, under different load, determining weakest position derrick. rigs are widely used filed drilling operation, due to their...
In this paper, a new heuristic algorithm for the two-dimensional rectangular packing problem (2drpp), Improved Lowest-level Best-Fit with Memory (ILBFM) algorithm, is presented. Three rules (ILBF) which belong to class of procedure that preserve lowest-level best-fit first, proposed. By combining ILBF rule Particle Swarm Optimization (PSO) local best sequence remembered, and retained in next generation particle swarm. our study, we compare hybrid terms solution quality on number problems...
Human activity recognition based on wireless signals emerges as a research hotspot recently. Though tremendous efforts have been devoted and significant progresses achieved, one fundamental issue still remains open, i.e., theoretical modeling between signal dynamics human activities. This paper fills in the blank by addressing several issues providing insightful mathematical analysis including signal-activity model. To validate such analysis, prototype system has built, where series of...
This study developed an unpowered knee exoskeleton which used the custom-built spiral spring to convert negative work assist extension during stair descent. The optimization of function angle and stiffness were conducted get optimal parameters. Six healthy participants descended fix-steps with without prototype, while rectus femoris (RF) biceps (BF) as selected muscle recorded sEMG signal. Results show that average mean normalized signals RF reduced by 6.12%-13.54%. use bilateral stores...
