The non-contacting measuring method for heat power using Cylindraceous Gardon type Sensor is proposed in this paper to meet the requirements of heat power measurement of heat source in cylindrical shape. A experimental testing device has been constructed. A series of experiments were carried out, and the relationships of output temperature difference, heat driven voltage, and input heat power are...
This paper established a simulation platform of intelligent fault diagnosis of traveling hydraulic system for multi-axle driving construction machinery using AMESim software. The corresponding parameter variations under the fault condition can be simulated by changing the parameters of related components in the simulation model, then the system response while the fault can be calculated so that fault...
The safe reliability assessment of coal mine safety system is a multifactor overall merit problem. In this paper, we firstly introduced the principle and method of coal mine safety assessment based on rough set - neural network - evidence theory. Secondly, we used rough set method to carry out the pretreatment of information. Thirdly, according to the information structure after treatment, we formed...
