An Experimental Investigation About Cable Efficiencies in Current Automotive Door Systems

Based on experimental and analytical research, a design tool was developed to estimate engineering parameters for side door latch inside release cables, given a pre-determined operating range. This design tool accurately estimates the cable efficiency for a set of parameters, thus significantly reducing the design time for latch and cable related engineering issues. Through testing and data analysis, the study determined the relationship between performance factors such as cable efficiency and effort losses, and design factors such as cable type, routing and loading conditions. Experimental data was used to generate curve fit equations that predict the cable efficiency for side a door latch system level development.
