Design and modeling using finite element analysis for the sitting posture of computer users based on ergonomic perspective.

COVID-19 all over the world has given an option to employees to work from home. As a result, the number of computer users has increased drastically. According to international market tracker Data Corporation, in 2020, the sales of computer devices exceeded 302 million. The survey conducted on computer users indicates that there was increase in neck pain and back pain. The increase in musculoskeletal disorder is mainly due to bad ergonomic design of computer workstation. The present work is focused on design of computer user chair based on Indian anthropometric standard data. Three different kinds of chair have been modeled in CATIA V5. The bio-mechanical analysis and rapid upper limb assessment analysis were carried out. The structural analyses of chairs have been carried out in ANSYS. The results showed that the chairs were structurally strong for static condition.
