基于受迫振动试验和有限元分析方法，研究了一种新型压电传感器在传统木结构动力特性评估中的适用性。新的传感器被开发用于结构健康监测的目的和一系列的强迫振动试验的五分之一规模的木制原型进行评估传感器的响应。原型结构对应于框架木结构，柱和梁之间的传统连接不使用钉子。这些节点由梁端组成，梁端相对于构件的其余部分变窄，并插入柱中的孔中。新的传感器被安装在选定的接头结构。从新的传感器测量获得的强迫振动试验的结果进行了讨论，在有关的分析过程中采用估计的振动特性和动态响应的目标结构，并获得良好的一致性，两者之间的结果。分析过程和测量结果吻合良好，验证了所采用方法的可靠性和所提出的新传感器的适用性。
The applicability of a new type of piezoelectric sensor to evaluate the dynamic characteristics of traditional wooden structures is investigated based on forced vibration tests and finite element analysis procedure. The new sensor was developed for structural health monitoring purposes and series of forced vibration tests on a one-fifth scale wooden prototype were performed to evaluate the sensor response. The prototype structure corresponds to a framed wooden construction with traditional connections between columns and beams where nails are not used. These joints consist of beam-ends narrowed with respect to the rest of the piece and inserted into a hole cut in the column. New sensors were installed in selected joints of the structure. The results of the forced vibration test obtained from new sensor measurements are discussed in relation to the analytical procedure adopted to estimate the vibration characteristics and dynamic response of the target structure, and good agreement was obtained between both results. With this good agreement of the analytical procedure and the measurement results, the reliability of the employed methodology and the applicability of the proposed new sensor were verified.
