Most do not consider there to be a risk in pushing on, bumping into or falling against an elevator door from the hallway side. However, the lack of the elevator cars presence alone, and the potential for severe injury or even death make this seemingly mundane situation potentially critical. Standards exist relative to such situations, and past and current designs attempt to account for this possibility, still people get injured interacting with these doors every year. In order to evaluate a real-world elevator door system's ability to withstand the quasi-static and impactive loads that can be placed on it by the general public during its life, both intentionally and unintentionally, a predictive tool is needed. This work represents the combination of empirical laboratory testing and numerical modeling of a typical elevator door system exposed to quasi-static and dynamic loading. The test procedures and methodology employed in this work provided repeatable and reliable results in quasi-static and dynamic testing. Numerical simulation using MADYMO established a robust and accurate quasi-static model of a primary door failure mode. The quasi-static MADYMO model can be used for quasi-static loading at any height of load application on the door and at any gib engagement depth up to full engagement with reliable and repeatable results. The dynamic MADYMO model showed accuracy at the 3 mm (0.12 in.) gib engagement depth at any contact height and any contact speed. A preliminary 6 mm (0.24 in.) gib engagement depth dynamic model has been verified for full-mass impacts of up to 1.5 m/s (4.8 ft/s).
