The capacitive ultrasonic transducer (CMUT) was initially proposed for temperature measurement. A simple CMUT structure and the corresponding matching circuits were designed. Then the effects of vibration modes and bias voltage on sensitivity were analyzed by the finite element method. The results showed that the resonant frequency varied almost linearly with the temperature over the range of 45 °C...
In this paper, T-type adhesively bonded joint peel test is served as simulation object, to explore a efficiently approach to model T-type adhesive bonded joint and to predict it's failure. Firstly, T-type adhesively bonded joint peel tests were conducted. Base on the measured data, load-displacement curve were plot. Secondly, on the basis of DYNA, a finite element model of T-type adhesive bonded joint...
Aiming at the difficulty of force control in impedance control lies in the unknown parameters of the environment, a reference trajectory generation approach for impedance control is presented, which uses neural networks to estimate the environment parameters. In this method, the environment parameters are estimated by a neural network (NN1), which constructs the relationship between the environment...
