Abstract
An industrial safety helmet is used to protect our head from the objects that are falling on the helmet by absorbing mechanical energy. The number of workers getting head injuries in the construction and industries are increasing every year. The risk of injuries can be reduced significantly by wearing an appropriate safety helmet. At present, the helmet used in the industry has low stiffness because of improper filling of material and uneven pressure distribution. In this paper, an effort has been taken to improve the stiffness of the industrial safety helmet by modifying the existing design. The stiffness of the industrial safety helmet is determined by doing the finite element analysis in ABAQUS. Acrylonitrile butadiene styrene (ABS) and natural fiber are preferred as the materials for the helmet. CATIA V5 is used for modeling the helmet, and the analysis is carried out using ABAQUS software. The standard design and modified design are analyzed, and the results are noted and also the suggestions are given for changing the design to improve the stiffness. The standard designed helmet is modified, and the analysis is done for the modified designed helmet. At last, the results of both the helmet are compared, and it is found that the newly designed helmet has better stiffness than the standard designed helmet.
