Analysis of the Behavior of a Cross-Type Hydraulic Outrigger and Stabilizer Operating Under Determined Loads

In this study, behavior of a fully opened cross type hydraulic outrigger and stabilizer of an aerial ladder fire-fighting device which is on determined static load is analyzed. This hydraulic outriggers and stabilizer are designed via SOLIDWORKS 2017 software and then analyzing process is run at SIEMENS NX 11.0 NASTRAN software. The location of the center of gravity of the firefighting device and its mass at several use cases is used as input for analysis. Standard equipment’s which can work with harmony are chosen for model, since design of a commercially producible model is aimed. Stress, strain values and forces acting on mills are obtained by analysis and then interpreted. When displacement of mass against gravity is 13 mm, displacement of outrigger and stabilizers system is ±4. The maximum stress at system is obtained as 190 MPa when singular values are filtered. Factor of safety is determined as 1,9 for this system. The system is decided as durable according to this study.
