| Abstract [eng] |
The paper analyzes the possibility to use automatic slide-gate type fire dampers with multiple blades superposed with the linear induction motor secondary elements in dust explosions localization systems with large cross-section ductworks. Sheet metal type blades stress-strain state computations by means of finite element method and studies of dynamics of fire dampers linear electric actuators by means of Matlab Simulink computer model were performed. It was obtained that the dampers blades thickness minimization reduces their response time about two times, closing force – near 30 %. |
