Gearboxes are important parts of mechanical transmission systems, so that it is very pivotal for avoiding future catastrophic failures to detect faults in gearboxes at the early stage. Various vibration analysis techniques have been proposed and successfully applied to detect faults in gearboxes. The outputs of these techniques are used to identify the signal changes caused by defects. Because of...
Multi-loop model of asynchronous motor contains lots of parameters, which leads to problems such as complex calculations, difficulty in equations solution and so on. In this paper, a simplified asynchronous motor model is set up on the basis of MATLAB®/Simulink environment to imitate health states of stator inter-turn short and broken rotor bars by simulating and studying their asymmetric fault features...
Propellant filling system is one of the key components of liquid rocket engine test bed and improving its reliability and security is very necessary. However because of the shortage of failure data and high expense and risk of test experiments, modeling and fault simulation are urgently needed. Based on the modular modeling, a new method using the objected-oriented language Modelica in Dymola is proposed...
