The refined theory provides the solutions of torsional deformation of a circular shaft without ad hoc assumptions. Exact solutions, including a Saint-Venant's solution part and a transcendental part, are obtaine
Therefore, only the torsional deformation of the shaft is considered. Figure 1 Physical model (This figure was created via Visio 2013, http://sj.njlhwlc.cn/pg/178.html, Figs. 2, 3, 4, 5, 12 and 21 were also created by Visio). Full size image Figure 1 shows a circular shaft ...
Wang Zhiqiao et al. theoretically analyzed the deformation angle of a solid circular rod and established the relationship curve between deformation and swift effect21. Jia H. K. et al. analyzed the error of the existing torsional deformation measurement methods and...
Thus, this quantity represents resistance to twisting deformation in the structural member. A solid circular shaft with a radius r For a solid circle of radius "r," the polar moment of inertia is given by the formula: {eq}J=\frac{\pi r^{4}}{2} {/eq} In terms of diameter (d), ...
(Barj et al., 2014). The torques to which the structure is subjected can also cause structural deformation. In response to this problem, more and more rotational inertia dampers are being focused on and developed. To address the problem oftorsional vibrationon offshore platforms,Ma et al. (...
The torque must not exceed the elastic deformation of the material. The shaft cross-section has to be circular. The length of the shaft must not change during loading. Torsional Stress vs. Bending Stress Both bending and torsional loads are moments, in which a force is applied at a distance...
From the angular displacement (ϕ) and known shear modulus, G, an approximation of Js (which is a strictly geometric parameter) was obtained using the below equation for the torsional deflection of a circular shaft:(3)ϕ=LTJsG From the resulting surface profile of Js values, the torsional...
A circular shaft of uniform cross section loaded at the end by a torque rotates about the longitudinal axis. The only deformation in the specimen is the rotation of the cross sections with respect to each other. This means that no longitudinal stress of any account are developed during ...
of rotation of said tortional vibration dampener, and wherein said apertures essentially have a circular ring sector configuration and are uniformly spaced apart; intermediate parts disposed in said apertures of said primary part, wherein said intermediate parts also have a circular ring sector ...
2) torsion of circular shaft 圆轴的扭转 3) Twist stress 扭转应力 1. The experimental results showed as follows: under the cyclic twist stress, the bottom of flat teeth of spline shaft fissured with stress concentration that it was due to machining and installing imprudence. ...
