This paper investigates design, modelling, and test issues related to
piezoelectric energy transducer. The model analyzes a rail-borne “seismic”
energy harvester that is designed to generate electrical energy from local
variations in rail acceleration. The energy harvester analyzed in this model
consists of a piezoelectric PZT film clamped at one end to the rail with a tip
mass mounted on its othe... hiện toàn bộ
In the big data background, the accuracy of fault diagnosis and recognition has
been difficult to be improved. The deep neural network was used to recognize the
diagnosis rate of the bearing with four kinds of conditions and compared with
traditional BP neural network, genetic neural network and particle swarm neural
network. Results showed that the diagnosis accuracy and convergence rate of the

The active car suspension system is presented here to suppress the vibration of
the car by applying proportional derivative (PD) and positive position feedback
(PPF) controllers with time delay. The control signal output of the controller
is applied electrically to the magneto-rheological (MR) damper or
Electrical-rheological (ER) damper which is attached parallel to the passive
components to impr... hiện toàn bộ
