Abstract: Applying the fault tree analysis to hydraulic pumping system of concrete pump truck, the fault tree failure model is set up. Through the qualitative analysis of the fault tree, the minimum cuts are obtained. With the quantitative analysis, we calculate the top event probability and the importance degree of bottom event occurrence. Combining analytic hierarchy with fault frequency of hydraulic pumping system, the fuzziness of assessment of bottom event probability is estimated. With reference to the qualitative analysis and the quantitative analysis, we formulate the measures of preventing the concrete pump hydraulic system failure.
