Ergonomic risk assessment in an injector subassembly workstation using the RULA method

Abstract

Ergonomics is the science that studies the relationship between humans and their work environment. It analyzes how work is performed and takes into account the tools and movements that are executed. Ergonomic studies have shown the importance of evaluating work environments to propose solutions that benefit both the health of workers and the economic well-being of companies. This project was carried out in an automotive manufacturing company, where an ergonomic analysis was performed. The RULA method was applied to evaluate risks, identifying three main postures that compromise the safety and physical integrity of workers due to the high level of risk. The results obtained allowed the proposal of an improvement, which consists of the implementation of a collaborative robot, which not only mitigates the risk but also provides an economic benefit for the company.
