Verification of Humanoid Robot Model Considering Stick/Slip Friction
Abstract: Biped locomotion created by referring to ZMP criterion to keep a robot stable during walking have contributed to promising humanoid’s walking strategies, having realized stable walking of real humanoid robots. However the walking strategies having been proposed so far including ZMP-based stabilization method seem to be constructed on assumption that the slippage doesn’t occur. In this...
متن کاملAnalytical Approach to Vibration Analysis Of the Wheel-rail contact
Wheel/rail contact simulation is one of the most complicated problems in the modeling of railway vehicles. The wheel/rail interaction plays a unique role in rail vehicle dynamics. In this paper, the dynamic response of the wheel on irregular rail track is analyzed with analytical approach using the method of Multiple Scales (MMS). The Hertzian contact theory is used to obtain the relationshi...

متن کاملVibration of Train-Rail-Bridge Interaction Considering Rail Irregularity with Arbitrary Wavelength
A generation method for the rail random irregularity with arbitrary wavelength interval (WI) is developed, and its accuracy and efficiency are demonstrated. Then a moving wheel-rail-bridge interaction element is derived to establish the finite element equations of motion for the train-rail-bridge interaction system, and the flow chart of assembly and calculation for the system equations is give...
متن کاملinvestigation of rail track vibration due to fractured sleepers
in this paper effects of fractured sleepers on rail track vibration under moving wheelset have been investigated. two parallel rails of the track have been modeled as euler-bernoulli beams on elastic points as rail pads. also sleepers have been modeled as visco-elastic euler-bernoulli beams. it is assumed that, some sleepers under the rail track have been fractured and modeled by two beams. the...
