  • The influence of traction rod arrangement modes on locomotive running safety was researched to develope new bogies with single traction rod for 200 km·h-1 locomotive with six axles(i.e.2C0), a dynamics model of locomotive with driving equipment flexibly suspended on frame and six axles was established by SIMPACK.Under the conditions of traction, braking and passing through irregularity track, when traction rods acted at the middle or two ends of car body, locomotive behaviors through tangent or curved tracks were analyzed.Analysis result shows that the positions of the rod have tiny effect on the dynamics performances of locomotive, and the plan of traction rod acting at two ends of car body is suggested to simplify the design and manufacture of car body.The locomotive can pass safely through the S shape curves with R400 m and R1 600 m radii; lateral force passing through the curve with R400 m radius is larger than that under driving and braking conditions, and wheel unloading ratio on braking condition is larger; lateral force under passing or tracting through the curve with R2 800 m radius is larger than that on braking condition.
