For large structure, to detect the effect of vibration isolation, the technique of structural dynamic analysis based on the frequency response method has presently been formed. But for midget structure such as aircraft instruments, to detect their effects of vibration isolation, there have been no ideal measuring means. According to the laser interference principle, holography has been used in detecting the effect of vibration isolation in midget structure such as integrated circuit plate on different supports and with different exciting frequencies. The effect of vibration isolation of simulated structure has also been detected under different exciting frequencies with different isolation materials. These experiments have shown that the technique has several advantages, such as high accuracy, noncontact and whole field analysis. This article also describes the recursive formula of the structure displacement field derived from the character of Bessel's function. The relative error caused by this formula is less than 10~(-4). We have also made necessary qualitative and quantative analyses to the experimental result.

对于大型结构隔振效果的测定,目前已形成了以频响方法为基础的结构动力分析技术。但对于小型仪器、仪表那样的结构,由于传感元件小型化的限制,其隔振效果的检测,还没有理想的测试手段。本文根据激光全息测振原理,对小型集成电路板在不同支承条件下的隔振效果作了全息测定;还用不同隔振材料,在不同激振频率下,对模拟结构的隔振效果作了测定。实验表明上法对非接触全场检测隔振效果是可行的。本文还给出了计算位移场的递推公式,并对实验结果作了定性和定量的分析。

This paper provides a computer modelling method Simulating a destructive test of 0.5-scale 4-storeyed building for calculating the elasto-plastic shear-wall structures by using the "continuum approach" model as its mathematical model of analysis which in the past could only be used for elastic structures.Besides,in order to have better result of analysis, the first storey of the analyzed building is kept in its prototype without using the continuum approach model. The main points of this method is to employ the equivalant continuous medium replacing the connecting beams between those coupled walls associated with the equivalent constant stiffness of all components (beams or walls) which are located at the same vertical row.This equivalent constant stiffness is used to replace the real stiffness of different components.The variety of real stiffness at the same row is caused by the fact that some components have already been destroyed (or have yielded)under loads while some of them are still kept within the elastic range.Here, the equivalent constant stiffness is counted in accordance with the equivalence of the def ormational energy stored up at the same vertical row.After knowing the general deformation of the whole structure the internal stresses of different components will be distributed according to their real stiffness and then the new lots of destruction will be determined and used for another round of loading.

本文是将过去仅用于弹性结构计算的连续化分析法,推广应用于弹-塑性结构计算,用以利用计算机模拟结构试验,计算出结构破坏过程,并为提高计算精度,对首层采用原型(非连续化)分析。本文方法与现有的离散化有限元法相比,具有输入数据简单,运算速度快,大大节省计算机内存与机时的优点。本文方法的要点在于采用连续化分析的同时,辅以结构已局部破损部位的刚度退化修改,再进行按同一竖列内部变形能量等效的再度刚度连续化,进入下一级荷载下的分析,并在求得整体变形后,还原到非连续化的实际刚度,进行各部位的内力分配计算,求出新一轮的破损位置。如此步步计算,直到最后阶段。
