Abstract This paper presents an electromagnetic energy harvester based on a unique nonlinear Kresling origami-inspired structure. By introducing the equilibrium shift phenomenon, reversible nonlinearity (i.e. mixed softening-hardening behavior) empowers proposed to work in broad frequency band, confirmed by both simulation using dynamic model and experimentation. The prototyped device can produce open-circuit root mean square (RMS) voltage from 0.09 V 0.20 reversibly response region (6.19...
It is known that piezoelectric material shunted with external circuits can convert mechanical energy to electrical energy, which so called shunt damping technology. In this paper, a stacks ring (PSR) designed for vibration control of beams and rotor systems. A relative simple electromechanical model an Euler Bernoulli beam supported by two resonant RL established. The equation motion such simplified system has been derived using Hamilton’s principle. more realistic FEA developed. numerical...

6_PUS parallel mechanism is a new type manipulator which has two guide rails, along six sliders connected with tie rods by hooke joints are driven linear motor and then motion platform rods. In order to obtain precision loci of platform, should be controlled exactly. During the modeling mechanism, RBF NN selected approach nonlinear this manipulator, neuron PID controller used regulate object. paper, regulating rules control system introduced in detail, efficiency proved experiments show...
In this paper, the surface morphology method is improved and bit-rock interaction model between rock PDC bit studied, considering influence of blades’ shape cutters’ arrangement. Based on model, dynamic deep drilling system equipped with arbitrary established, stability prediction proposed. method, characteristics four different types (an actual bit, a Tian blades, traditional bit) are comparing based polygon clipping. The results indicate that arrangement nonlinear vibration cannot be...
A new kind of parallel mechanism used for faster response and higher maneuverability test wind tunnel is introduced. Based on static equilibrium analysis screw theory, the equation motion platform established, then kinematic Jaccobian matrix achieved by use force matrix. By means singularity 6_PUS analyzed three kinds their conditions are identified.
Several crucial parameters to a new type of 6PUS parallel mechanism is introduced in this paper. In order select optimization kinematics performance index, evaluated method for index concluded and it’s full working field loci sample arithmetic built calculate condition number Jaccobian matrix that was proved important performance. Based on theory study according Kinematics optimized are obtained. The research results show the preferable range length motion platform from 0.45m 0.50m width...
Most research about using piezoelectric stacks to suppress vibration of mechanical structures didn’t involve the similarity problem for stacks. The goal this paper is investigate dynamic between a prototype piezo stack and scaled up or down stack, whilst discussing feasibility predicting structure which use control. To illustrate concisely, single-DOF system consists proof mass shunted with series RL circuit considered. Firstly, governing equation such piezo-electromechanical in frequency...
