Study on Stress and Deformation of an Elevator Safety Gear Brake Block Using Experimental and FEA Methods

Abstract

It has been seen that Cylindrical Type Instantaneous Safety Gear, which is one of the most important element of an elevator system, during safety gear operation is being exposed to high stresses and brake accelerations. The stress and deformation distribution of a cylindrical type safety gear’s brake block was investigated using finite elements and experimental methods. Results found with FEM by using ABAQUS/CAE software were compared to experimental results. It is clearly seen that the element type and boundary conditions used in finite element modelling give satisfactory results.
