“…There are mainly three types of sensors in the aforementioned or other researches used in WIM systems: strain sensor [8,13], piezoelectric sensor [4], and quartz sensor [18]. Among the available sensors, piezoelectric sensors have been attracting increasing interests due to their ability of self-powering and fast response to impact loadings [19][20][21][22][23], and, hence, have been widely applied in health monitoring systems for infrastructures [24][25][26][27]. Tang et al [28] used integrated Lead Zirconium Titanate (PZT) sensors for comprehensive structural health monitoring.…”

More and more researches have been carried out recently on Weigh-In-Motion (WIM) technology for solving the traffic safety problems caused by overload. In this article, we aim to study the measurement accuracy of the WIM system. Based on the electromechanical theory and elastic half-space method, we establish a theoretical model of multi-layer structure to investigate the correlation between the output voltage of the piezoelectric sensor and the applied force. In addition, we performed cyclic and moving load experiments to verify the accuracy of the analytical calculations. The load magnitude identified by this theoretical model matched the experiments very well, which shows that this model is effective for the WIM system. In addition, we proved that the load frequency is an important factor affecting the measurement accuracy of the sensor, which further enables us to design more suitable sensors for certain use scenarios.

To make sure the safety, durability, and serviceability of structures in-service, health monitoring systems (HMS) are widely used in management of civil infrastructures in recent years. Compared with traditional force sensors, lead zirconium titanate (PZT) sensor performs better in smart sensing in HMS with advantages of high sensitivity, self-powering and fast response to highly dynamic load. Here, we propose to utilize PZT sensor arrays to identify the position and magnitude of external loads that are applied on a simply supported beam. An identification method is proposed based on experimental tests and theoretical electromechanical analyses, which is proved effective by comparing the identified parameters with the actually applied loading conditions and signals recorded by commercial force sensors. Experimental observations also reveal that PZT sensors respond faster to loading process than commercial force sensor, which makes it qualified in identification of transient loading such as impact processing in loading history. Results also demonstrate the applicability of the method to identify multiple concentrated load and the average moving speed of the applied load. The current method may provide a useful tool for identifying load conditions on various beam structures.
