摘要

提出了一个数学模型,供工程师、技术专家和空间技术研究人员使用,机械科学必须在高温下运行。研究了粘弹性方板自由振动频率的二维热效应。在本文中,厚度在X方向上呈抛物线变化,热效应在一个方向上呈线性变化,在另一个方向上呈抛物线变化。采用瑞利-里兹法计算基频。利用最新的MATLAB计算技术,对锥度参数和温度梯度的不同取值进行了频率模态的计算。版权所有©www.iiste.org关键词:粘弹性,方形板,振动,热梯度,锥度常数,非均匀性。

A BRIEF REPORT ON SCALE INDEPENDENT QUANTUM COSMOLOGY
A mathematical model is presented for the use of engineers, technocrats and research workers in space technology, mechanical Sciences have to operate under elevated temperatures. Two dimensional thermal effects on frequency of free vibrations of a visco-elastic square plate is considered. In this paper, the thickness varies parabolic in X- direction and thermal effect is vary linearly in one direction and parabolic in another direction. Rayleigh Ritz method is used to evaluate the fundamental frequencies. Both the modes of the frequency are calculated by the latest computational technique, MATLAB, for the various values of taper parameters and temperature gradient.
