Study on Friction of Bearing Cable and Saddle with Different Material in Freight Ropeways

Abstract:

The contract model of the freight ropeways bearing cable and the saddle is established by FEM software, and the simulation calculation is carried out. The calculating formula for total contact pressure is fitted from the analysis result. According to setting requirement of the freight ropeway, simulation calculations of the different bearing cables are carried out under different operation conditions, and the relationships are obtained between contact pressure and influent factors, such as curvature radius of the saddle, the envelope angle and the drawing force. The results shows that contact pressure is in inverse proportion to the curvature radius of the saddle, in direct proportion to envelope angles and drawing force of the cable. Friction force between the bearing cable and the saddle made of nylon, bronze and steel three different materials are summarized through field test, and the friction coefficients applicable to the saddle of different material are obtained in combination with simulation results of the touch models.
