In response to the poor adaptability of existing harvesters complex operating conditions in field, this study took a three-row four-wheel-drive (4WD) corn harvester as research object, designed traveling transmission system layout, proposed control strategy driving torque distribution, simulated, and analyzed each four states drive wheels slippage. The results showed that under slipping conditi...

In this study, we investigate the relationship between the skill level of subjects and their utilization of joint torque components, i.e., muscular torque, interaction torque and gravity torque. Results show that the subjects whose scores are high utilize the interaction torque of the elbow joint without shoulder displacement. Keywords— darts throwing, motion capturing, interaction torque

I . Introduction Multi-phase machines offer several key features, such as high reliability, high torque density, and high efficiency . Therefore, they are obtained wide applications from automotive to aerospace [1][2] . One of them is the five-phase PM machine, where the torque density can be improved by injecting third harmonic current . However, in order to maintain high torque density and re...

Rheology of the solid and melted cheese depends upon their functional properties. Farinograph is used for quality determination of wheat flour dough. Determination of the rheological properties of dough and dough like food materials from Farinograph is easy while study of cheese characteristics is very difficult and complicated. The present study is therefore designed for the possibility of qua...

Title of dissertation: THE IMAGE TORQUE OPERATOR FOR MID-LEVEL VISION: THEORY AND EXPERIMENT Morimichi Nishigaki, Doctor of Philosophy, 2012 Dissertation directed by: Professor Yiannis Aloimonos Department of Computer Science A problem central to visual scene understanding and computer vision is to extract semantically meaningful parts of images. A visual scene consists of objects, and the obje...

Torque-saturated control laws for spacecraft attitude control are considered. These control laws require no knowledge of the mass distribution of the spacecraft and thus are inertia-free. We examine two specific problems. In the first problem, the spacecraft has an arbitrary initial attitude and angular velocity, and the objective is to bring the spacecraft to rest with a specified attitude. In...

in this paper, a new field oriented control scheme with maximum torque for permanent magnet hysteresis synchronous (pmhs) motor has been presented. vector control method provides significant improvement to the dynamic performance of ac motors but in this method d- axis current is controlled such as the ratio of motor torque to motor current is a maximum, then the dynamic performance will be ver...

In this paper, at first, a 24/16 three-phase switched reluctance motor is designed, then the rotor poles shape tips corrected for reduction ripple of single-phase torque waveform. By doing this, the single-phase torque waveform has a flat surface and consequently, the single-phase torque ripple is reduced. Also, due to the commutation between the machine phases, the torque drops during this tim...

Tightening of the screws in implant-supported restorations has been reported to be problematic, in that if the applied torque is too low, screw loosening occurs. If the torque is too high, then screw fracture can take place. Thus, accuracy of the torque driver is of the utmost importance. This study evaluated 4 new electronic torque drivers (controls) and 10 test electronic torque drivers, whic...
