ABSTRACT
The use of structural calculation software based on finite element analysis is nowadays a common practice when designing new industrial products processed from thermoplastic materials like polyamides or ABS. in order to make an adequate Prediction of the service behavior of the plastics component, it is Essential to carry out appropriate analysis when working with the software. This requires both the correct mechanical characterization of the materials used for inputting the required properties in the calculation code, and the specification of the different solution characteristics. In this work, two materials (polyamide and ABS) have been studied for the analysis of single disc machine. The single disc machine includes top cover and bottom cover. Where the top cover consist of motor, pulley and the provision provided for inserting the handle of the machine. The analysis of the top cover is to increase the contact force between the brush and surface. for that a mass of 12kg is Placed on the space provide for the top cover and The structural analysis should be carried out in the top cover in order to reduce the maximum stress and deformation level within the safe limit. Whereas The linear impact analysis is carried out on the bottom cover in order to find a good stiffness level and the minimum hand force at an angle of 60 degree is required for the machine avoid to hitting the wall. for that to make a slot on the bottom cover and place a rubber bush in the slot to reduce the deformation level as well as life time of the machine will also increased. This simulation tests are conducted in the finite element code ANSYS and stress deformation is calculated to achieve the efficient material.
