WC35Y drainage pump truck is an emergency rescue equipment designed for poor drainage in mines. The design of its steering mechanism is the premise to ensure the normal use of the stuck pump truck. Through Adams analysis of the load change of each connecting rod when the drainage pump turns, it is concluded that the maximum load of KL is 168000 N. The strength of each knuckle arm and steering rod of steering mechanism is analyzed by Abaqus. The stress of the center knuckle arm and the end knuckle arm are 106.5 MPa and 44.7 MPa, respectively,and zhe deformation is small. The stress of the steering rod TS under the ultimate load is 312 MPa,which basically meets the application requirements.
