Angular displacement sensor is taken as object of rearch to discuss influence of sensors installation error on super-elevation measurement. The error analysis models are established by using analytic geometry method. Experimental data are required under the condition of 25 ℃ and 50 % relative humidity( RH) to verify effectiveness and reliability of the simulation models. The result shows that the installation error should not more than 1°
if the requirement of super-elevation measurement precision shoule meet ± 0. 5 mm.
