Design Analysis for Gear Motor System Assembly to Automate the Rolling Shutter Operation-FEA Results

Over the years roller shutters have been used for security purpose with opening and closing feature in every commercial as well as residential areas like doors for vans, garages, shops, schools, prisons and warehouses, if not maintained properly get rusted, and it takes lot of effort to lift them, usually this effort is so high that it can cause back injury to the operator. Even for large size shutters it is impossible to lift them without any mechanism. Considering these problems it is important to design a motorized system which can facilitate the opening and closing of shutter by the press of the button and thus reduce the back injuries. Thus it is important to design such mechanism for safety purpose. In this project keeping in mind those problems, we have designed Gear Motor system assembly to automate the Rolling shutter operation that can provide safety to the operator. First we have studied different types of shutters available in the market and accumulated the design specification for selected shutter from the manufacturer. Using this design specification a CAD model of Gear motor system assembly of rolling shutter modeled in CAD software solidworks. In fem software HYPERMESH mesh model of the Gear motor system assembly generated and processed to the linear static analysis using NASTRAN. From the results we concluded that stresses obtained in static analysis are within the limits, hence the design of gear motor assembly to automate the rolling shutter operation is safe.
