raction power computer simulation software has changed in the last 20 years. The tool has evolved from simpler, DOS-based, energy management software to detailed, Windowsbased, user friendly, analytical software that can accurately model train performance, predict train voltages, and produce a train voltage profile for an entire rail system. Traction power computer simulation software is now us...

Fault diagnosis of downhole traction robot has characteristics special mechanical structure, complicated working condition and lack research data. In this paper, a method fault analysis tractor hydraulic system based on model is presented. The failure mode mechanism key components in telescopic are analyzed. proposed the mathematical component. Based AMESim, established, single multi-fault simu...

A hybrid electric vehicle (HEV) has two types of energy storage units, electricity and fuel. Electricity means that a battery (sometimes assisted by ultracaps) is used to store the energy, and that an electromotor (from now on called motor) will be used as traction motor. Fuel means that a tank is required, and that an Internal Combustion Engine (ICE, from now on called engine) is used to gener...

This paper presents a vertical vibration model for 2:1-roping traction elevator system. In this model, masses of suspension ropes are considered and their kinetic energy is calculated by applying Rayleigh method. Equations motion free derived. To verify the improvement an output dependent only modal test scheme using eigenvalue realization algorithm conducted to obtain natural frequencies from ...

Climbing on vertical concrete structures like bridge pylons or dams is still a great challenge for autonomous robots. This paper presents the forceand traction control system of the climbing robot Cromsci which uses a negative pressure system for adhesion and driven wheels for propulsion. Especially in vertical environments the propulsion system must be able to produce enough force for carrying...
