Arch tensile force adjustment method based on multiple regression analysis

The present invention provides a method for adjusting tensile force Arch multivariate regression analysis, comprising the steps of: measuring the boom internal force before adjustment; the regulated tensile force vector calculation, calculate the tensile force of impact matrix to calculate the sensitivity coefficients boom ; the sensitivity coefficient boom descending order, excluding the minimum sensitivity coefficient boom, boom remaining to be tensioned as the present boom; calculated using multivariate regression analysis method to be applied tension boom adjustment vector all boom and boom tensioning force error; repeat the above steps when one-out relatively minimal sensitivity coefficient boom, a jib boom when a tensile force error is 5% or more, then the last calculated determination applied tensile force adjustment vector as the boom to be applied tensile force is adjusted. The present invention utilizes differences in the sensitivity of Bridge boom, can effectively reduce the amount of adjusting the boom, high efficiency.
