Dynamic disturbance sources affecting the optical performance of the Thirty Meter Telescope (TMT) include unsteady wind forces inside the observatory enclosure acting directly on the telescope ...
A wave rotor constant volume combustor (WRCVC) was designed and built as a collaborative work of Rolls Royce LibertyWorks, Indiana University-Purdue University at Indianapolis (IUPUI), and Purdue Univ...
Video image sequences often give important information about dynamics of human motion in the field of rehabilitation or sports training. In order to understand dynamic analysis of the natural human mo...
This study presents a newly developed simple and cordless system, that consists of a gyro sensor and is connected to a small easily wearable personal computer (WPC) of a wrist watch type. The lithium ...
A radar uses the time elapsed between the transmission and reception of an electromagnetic waveform to locate targets present in the illuminated area. Different objects will reflect the radiation wi...
This paper is concerned with the earthquake analysis of suspension bridges, in which the effects of large deflections are taken into account. The first part of the study deals with an iteration scheme...
Instead of using the previous straight beam element to approximate the curved beam, in this paper, a curvilinear coordinate is employed to describe the deformations,and a new curved beam element is pr...
Relative carrying capacity of resources is an index to measure sustainable development through carrying capacity. Case studies of eleven cities in Zhejiang (Hangzhou, Ningbo, Wenzhou, Jiaxing, Huzhou,...
In our study, the nonlinear dynamics of mitral valve Doppler signals from 32 healthy and 28 patients with mitral valve stenosis was evaluated using by the computation of Lyapunov exponents, correlatio...
把机床传动丝杠简化为承受预拉伸力和移动力作用的旋转Timoshenko梁,综合考虑了陀螺效应、预拉伸力和移动力对丝杠振动的影响,以及丝杠两端轴承的支承作用,建立了弹性支承条件下丝杠的频率方程,利用拉格朗日方程建立了丝杠的动力学模型,利用振型叠加原理和隆格-库塔法求解,分析了系统参数对丝杠涡动转速和横向振动的影响。
In this study, a boundary element formulation having nonlocal boundary conditions is presented for the dynamic analysis of a two-phase composite. Nonlocal boundary conditions, used in the formulation,...
Energy consumption in buildings, in schools as well, in Serbia and Montenegro is significantly higher than is defined in world's energy standards. Heating energy is the biggest part of total energy co...
In this study, Eulerian and Lagrangian finite element formulations are given for the dynamic interaction problem of a fluid-structure system. Non-linear dynamic analyses of Karakaya arch dam were perf...
The horizontal coolant channel is one of the important parts of primary heat transport system in PHWR type of reactors. There are in all 392 channels in the core of Indian 540 MWe reactor. Each ...
在考虑物料非线性作用力基础上建立含有物料结合系数的倾角振动输送机力学模型,采用解析法对该模型进行求解与分析。分析结果表明:当工作面有倾角时物料结合系数比工作面无倾角时小;物料结合系数与阻尼系数随着振幅的增大而减小,其中物料结合系数减小较快;物料结合系数随着转速的增加而减小。
