FEM and Discomfort Analysis of Different Muscles and Joints During Welding Operation

SUMAN DAS, Debamalya Banerjee, Sabarni Chakrabarty, Shankarashis Mukherjee


Discomfort and injuries are highly associated with different joints and muscles in welding operation. Knee, wrist, hip, elbow and glenohumeral joints are the most complex and maximum used joints in human anatomy. Stabilities of these joints are the critical aspects which are provided by the different muscles and ligaments. The behavior of the different joints and muscles during operation is the major concerns for discomfort and injury analysis. The objective of this present research work is to obtain the intensity and distribution of stresses and discomfort level in the different joints and muscles during welding operation. The three-dimensional (3D) CAD model of the entire human body is developed in solid works software and FEM is used for stress analysis. The maximum von Mises stresses are also notice. It is observed that the intensity of stresses and the von Mises stresses are good injury indicators for the body muscles and joints independent of load direction. NIOSHs discomfort survey method is used for mapping the different areas of pain, dissatisfactions during the operation. This present research work provides a broad information’s to the researchers for better understanding about the most stressed muscles and joints during welding.
