ABSTRACT: Because of their technical advantages over ordinary metal springs, gas springs find usage in wide range of applications from furniture to aerospace industry as lifting, lowering or damping assists. Their integration to the tailgate operations in automotive industry is a challenging area, where not only the fundamental gas spring characteristics but also the mounting settings, working environment and tailgate body structure should be considered. The design and integration of these components will determine manual force exertion of operators thus the consideration of ergonomic characteristics of different populations is crucial. This paper introduces a recent visual academic software package, entitled TEM-SOFT, which is developed as a part of this research to perform ergo-mechanic simulations of tailgate operations with a fast, reliable and contemporary engineering approach and it is suitable for engineers and under-post graduate level students of mechanical and industrial engineering programs in the universities. The software developed and presented in this paper features all aspects of tailgate-gas spring operations considering the assembly scheme, tailgate mass center, gas spring type and working temperature in order to compute the required manual forces and the individual and combined impacts of acting parameters. Sufficient amount of scenarios were considered and the results were evaluated and discussed extensively. In addition to the other key findings, conducted research has shown that stronger gas springs, more effectively tend to move the critical tailgate position angle—where no operator force is needed to keep the tailgate opening—to the initial phases of the opening operation. A trade-off of this benefit is a superior initial manual force during closing.
