Low-Cost Monitoring System of Sensors for Evaluating Dynamic Solicitations of Semitrailer Structure 2016 Access copy available to the general public Unrestricted Analysis of the fatigue life of a semitrailer structure necessitates identification of the loads and dynamic solicitations in the structure. These forces can be introduced in computer simulation software (multibody + finite element) for analysing the response of different design solutions to them.These numerical models must be validated and some parameters need to be measured directly in a field test with real vehicles under various driving conditions. In this study, a low-cost monitoring system is developed for application to a real fleet of semitrailers. According to the definition of the numerical model, the guidance of a virtual vehicle is defined by the three-dimensional kinematics of the kingpin. For characterisation of these movements, a monitoring system having a lowcost inertial measurement unit (IMU) and global positioning system (GPS) antennas is developed with different configurations to enable analysis of the best cost-benefit (result accuracy) solution, and an extended Kalman filter (EKF) that characterises the kinematic guidance of the kingpin is proposed. A semitrailer was equipped with the experimental low-cost monitoring systemand high-precision sensors (IMU, GPS) in order to validate the results obtained by the experimental low-cost monitoring system and the inertial-extended Kalman filter developed.The validated system has applicability in the low-cost monitoring of a fleet of real vehicles. info:eu-repo/grantAgreement/ES/MINECO/TRA2012-38826 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 1.704 2016 INSTRUMENTS & INSTRUMENTATION 26 / 58 = 0.448 2016 Q2 T2 ENGINEERING, ELECTRICAL & ELECTRONIC 126 / 260 = 0.485 2016 Q2 T2 0.273 2016 Control and Systems Engineering 2016 Q3 Instrumentation 2016 Q3 Electrical and Electronic Engineering 2016 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Mantaras, D.A.
