• Abstract:
  Cable guardrail systems have been increasing in popularity in recent years due to several perceived benefits over the ; commonly used W-beam guardrail. A non-proprietary design was desired as an alternative to the many proprietary designs ; available. A non-proprietary, high-tension, cable end terminal was necessary to accompany the non-proprietary, hightension, ; cable guardrail system under development. The objective of this research project was to develop design ; recommendations for a non-proprietary, high-tension, cable end terminal. An analysis of several cable guardrail end ; terminals was undertaken to identify any common features that may prove to be beneficial or detrimental to end terminal ; designs. Next, a study of the non-proprietary, low-tension system was conducted to determine the cause of vehicle ; instabilities in full-scale testing. Since the high-tension and low-tension, cable end terminal designs are similar, it is likely ; that any issues with the low-tension design will also be evident in testing of the high-tension design. ; LS-DYNA modeling of current cable terminal anchor hardware was then accomplished and compared to bogie ; testing results. The anchor model proved to be sufficiently accurate to preliminarily analyze alternative cable anchor ; designs. A final, optimized, high-tension, cable anchor design was produced along with alternative terminal post ; recommendations for continuing development of the non-proprietary, high-tension, cable end terminal.
