摘要

本文致力于研究一种新型结构小动态弯曲变形测量仪。与以往测量可变形体表面上某一点的伸长或压缩应变的应变计不同，本文提出的应变计测量的是可变形体表面上某一点的曲率变化，对伸长-压缩应变没有反应。该量规是由压电材料和弹性材料制成的分层棒。它利用直接压电效应发挥作用。为了有效研究表面上各点结构的变形状态，必须确定应变张量的所有分量。目前使用的测量仪只能测量伸长应变或压缩应变，无法全面反映应变状态。用新量具测量的弯曲应变来补充这些变形是非常重要的。

Piezoelectric Gauge of Small Dynamic Bending Strains

This paper is devoted to a new gauge of small dynamic bending deformations of structures. Unlike previously existing strain gauges that measure elongation or compression at a certain point on the surface of a deformable body, the proposed gauge measures the change in curvature at a point on the surface of a deformable body and does not respond to elongation–compression strains. The gauge is a layered bar made of piezoelectric and elastic materials. It functions using the direct piezoelectric effect. In order to competently study the deformed state of a structure at points on a surface, it is necessary to determine all components of the strain tensor. The gauges currently used measure only elongational or compressive strains, which does not provide a complete picture of the strain state. It is very important to complement these deformations with bending strains measured by the new gauge.

期刊介绍： BUILDINGS content is primarily staff-written and submitted information is evaluated by the editors for its value to the audience. Such information may be used in articles with appropriate attribution to the source. The editorial staff considers information on the following topics: -Issues directed at building owners and facility managers in North America -Issues relevant to existing buildings, including retrofits, maintenance and modernization -Solution-based content, such as tips and tricks -New construction but only with an eye to issues involving maintenance and operation We generally do not review the following topics because these are not relevant to our readers: -Information on the residential market with the exception of multifamily buildings -International news unrelated to the North American market -Real estate market updates or construction updates
