The dynamic parameters including the angular displacement, angular velocity and angular acceleration under the action of torque were analyzed. ... Z Ji,H Hong,X Yuan,... - 《Journal of Physics Conference》 被引量: 0发表: 2021年 METHOD FOR MEASURING ANGULAR VELOCITY AND ANGULAR ACCELERATION ...
The Reynolds stress gradient is substantially larger than the torque associated with the bulk ion viscosity and ion orbit loss in deuterium and helium, but not in hydrogen. The ultimate goal of this work is to link differences in the microscopic turbulence-flow interaction to the resulting ...
aThe frictional forces after 5000 rotations were measured by a friction torque transducer and transferred to a personal computer (PC) by a special data system at 100, 150, 200, 250, 300 and 350 C, respectively. 摩擦力,在5000自转由摩擦扭矩变换装置测量并且转移了到一台个人计算机的 (个人计算机...
In the past, much attention has been given the cutting action of polycrystalline diamond compact (PDC) bits to explain and mitigate stick-slip, without much emphasis on the frictional torque. However, it is important to understand that the torque generated on the remaining drillstring accounts for...
In particular, values of EMCA are calculated by using the torque method, which was recently adapted to VASP21,22. To show the quality of our results, the calculated ez-dependent ETotal and EMCA for a configuration of Fe81.25Ga18.75 are presented in the inset of Fig. 2(a). It is ...
This can be understood also from the power balance point of view. Motor mechanical power is speed * torque, while input power is voltage * current. At low speeds net mechanical power is ~ 0, therefore most of the energy is essentially converted into losses. Only ...
Landscheidt used one single dataset to produce this forecast which follows the solar torque readings that result from the changing solar orbit shape directly influenced by the planet positions. Once again he was in the ball park but I believe through Carl’s graph we can now drill down much ...
Once you have ways to measure lengths, time intervals and mass, you can get numbers for "force", and calibrate devices to produce given amounts of force (or torque, in the case of engines). You can then predict the effect that such devices will have on other object...
In this paper, a robotic knee-ankle orthosis (KAO) with SMA actuators is developed, and the estimation method is proposed to determine the joint torque. First, based on the analysis of human lower limbs structure and walking patterns, the mechanical design of the KAO that can achieve various...
