Abstract This paper presents an investigation on bifurcation of railway bogie behavior in the presence of nonlinearities which are yaw damping forces in longitudinal suspension system and the friction creepage model of thewheel/rail contact including clearance...

Abstract Robotic rovers equipped with articulated rocker-bogie suspension have aroused great interest after the explorations on Mars; this has also shifted to different types of terrestrial applications such as in agriculture, military, and rescue fields. The can be designed so that, when rover is flat horizontal ground, weight evenly distributed among wheels; way, all wheels same traction capa...

En la presente investigación se diseña y valida una geometría de suspensión tipo Rocker-Bogie basados en el análisis grados libertad para su futura implementación dentro del sector industria exploración espacial. Ello tiene como finalidad principal recolección, transporte basura desperdicios a sectores estratégicos las instalaciones, sorteando obstáculos diferente nivel, aunque también podría a...

4. Leg piece?Length to measurement from middle of popliteal space to 1 in. beyond heel. Breadth, 5 ins. at knee sloping to 4J ins. at foot end. 5. Foot piece?9 ins. by 4A i?s. This is fixed to leg piece by two 1-inch mortise and tenon joints. It is also nailed to the extension piece. 6. Extension piece?18 ins. by 6 ins. sloping to 5 ins at the top. A pulley (an empty thread reel on a stout nail...

Three current paths are proposed, and theoretical analysis laboratory tests carried out to investigate the root causes of bearing failure in IGBT inverter-fed locomotives EMUs. The three types that run through drive unit bearings axle box used on EMUs electric classified as primary side path, main traction system path between vehicles EMU or locomotive it hauls. research found EDM caused by com...
