A virtual prototype model of wall finishing robot is developed and the force situation in the working process has been analyzed. Applying SolidWorks and its CAE packages, operating characteristics under the real project condition are shown by simulation analysis so as to provide a reliable basis for the design and manufacture of the prototype.
In order to improve fuel economy and reduce exhaust gas emissions, hybrid and electric vehicles use the electric motor as a generator for regenerative brake during deceleration, which converts kinetic energy of the vehicle into electrical energy. To maximize the recovery of braking energy, special brake system is needed to blend control the regenerative brake force and hydraulic brake force. This...
This paper presents dynamic modeling for cross-spring pivots, based on the Beam Constraint Model (BCM) and Lagrangian method. The effect of vertical force is included in this model. The first natural frequency of the cross-spring pivot under vertical force is derived. The effects on the first natural frequency imposed by manufacturing errors are studied. The model predictions of the first natural...
The frame three-dimensional entity model of a formula racing car is established on CATIA software platform, and is analyzed by finite element through the ANSYS software. Through the analysis of the static typical working conditions of the frame (bending and torsion conditions of the frame), find the affluent parts of the strength and stiffness of the frame, reduce the number of pipe fittings and diminish...
In this paper, a 3 degree-of-freedom bearingless permanent magnet motor with axial active suspension is proposed. The structure and suspension principle of this novel bearingless permanent magnet motor are described in detail and its suspension mathematical models are constructed. Based on the mathematical models, a control system is designed for the new type bearingless permanent magnet motor. The...
