The mezquila brooklyn spectrum of probable emergency scenarios for escalators can be analyzed using a computational experiment based on a simulation model that describes the real properties (behavior) of an object in a number of key (reference) States.The reference points of the States of the object under study should be uniquely determined by the complexity of the boundary conditions, for example, by means of measuring tools.The adequately tuned model allows to interpolate intermediate and extrapolate probable States of the studied object.Such approach allows to refuse carrying out full-scale tests with loading of a design to a limiting condition, and thereby to save a resource on bearing capacity of a construction as a whole.
Purpose: risk Assessment in the operation of tunnel escalators type ET-2M, equipped with emergency brake with constant torque, without loading the structural elements to the limit state.Methods: vibration Portraiture using vibration measuring complex; modeling of dynamic processes using specialized modules SolidWorks Motion (complex kinematic and dynamic analysis of mechanisms) and SolidWorks Simulation software complex SolidWorks.Results, practical significance: improving the reliability of operation of tunnel escalators equipped with emergency pride empire bowling ball brakes with constant torque by extrapolating the technical condition on the basis of numerical experiment by means of computer aided design.
