Based on ANSYS finite Pop element software and combined with the physical properties of piezoelectric materials, the actuating properties of the new piezoelectric ceramic tubular actuator was simulated.In addition, the maximum displacement, output and response frequency characteristics of the actuator were obtained.The results shown that the actuat
Routing systems for outdoor space have become the focus of many research works.Such routing systems are based on spatial road networks where moving objects (such as cars) are affected by the directed roads and the movement of traffic, which may include traffic jams.Indoor routing, on the other hand, must take into account the features of indoor spa
This research devoted to studying the properties of sliding wear ofthree groups of copper alloys chosen to this study.They are Brass (70/30),Silicon bronze and Silicon-Brass.These three groups have been examinedby using (pin on Disc) apparatus under different wear conditions includingapplied loads and disc ceramics hardness is constant (35HRC).This
With the aid of disturbance observer strategy, this article aims to investigate Energy Supplements the disturbance rejection and stabilization problems for periodic piecewise time-varying systems that are subject to time-varying delays, parameter uncertainties, nonlinear perturbations and exogenous disturbances.To be more specific, the periodic pie
