In order to study the effects of steam curing system, silica fume and steel fibre on impact resistance UHPC, split Hopkinson pressure bar tests were used in study. Two regimes considered test, at 90 ℃ for 3 days standard curing. The amount replacement cement was 0 % 20 %, volume content 1 %. crystal pore structure XRD MIP utilised. test results demonstrate that failure mode UHPC after SHPB can be studied by concept fineness modulus residue (). Silica has little influence integrity impact,...
Self-oscillating systems possess the ability to convert ambient energy directly into mechanical work, and new types of self-oscillating are worth designing for practical applications in harvesters, engines actuators. Taking inspiration from four-stroke engine. A concept a self-rotating engine is presented on basis photothermally responsive materials, consisting liquid crystal elastomer (LCE) fiber, hinge turnplate, which can self-rotate under steady illumination. Based...
The achievement and control of desired motions in active machines often involves precise manipulation artificial muscles a distributed sequential manner, which poses significant challenges. A novel motion strategy based on self-oscillation offers distinctive benefits, such as direct energy harvesting from the ambient environment elimination complex controllers. Drawing inspiration automobiles, self-moving automobile designed for operation under steady illumination is developed, comprising...
The synchronization and group behaviors of self-excited coupled oscillators are common in nature deserve to be explored, for motions have the advantages actively collecting energy from environment, being autonomous, making equipment portable, so on. Based on light-powered composed liquid crystal elastomer (LCE) bars, two is theoretically studied. Numerical calculations show that oscillations system modes, in-phase mode anti-phase mode, which mainly determined by their interaction. time...
Self-oscillating systems can directly convert ambient energy to mechanical work, and new type self-oscillating are worth designing for applications in harvesters, engines, actuators. Taking inspiration from the hand drill, we have developed a novel self-rotating drill system, which is consist of turnplate liquid crystal elastomer (LCE) fiber under steady illumination. To investigate behaviors LCE proposed nonlinear theoretical model illumination based on well-established dynamic model....
A polymer fiber can spontaneously move and deform continuously when it is placed on the top of a hot surface, driven by its rapidly varying inhomogeneous thermal expansion. The erratic movement usually very complex hard to be controlled modeled. In this article, introducing small kinks end straight fiber, we created an energy barrier system rolls, consequently, roll unidirectionally surface or shuttle back forth, determined kinking angle size kinked segment. We have further developed...
The self-oscillating systems based on stimuli-responsive materials, without complex controllers and additional batteries, have great application prospects in the fields of intelligent machines, soft robotics, light-powered motors. Recently, periodic oscillation an LCE fiber with a mass block under illumination was reported. This system requires illumination, which limits self-sustained systems. In this paper, we creatively proposed liquid crystal elastomer (LCE) spring oscillator...
For complex micro-active machines or micro-robotics, it is crucial to clarify the coupling and collective motion of their multiple self-oscillators. In this article, we construct two joint liquid crystal elastomer (LCE) spring oscillators connected by a theoretically investigate based on well-established dynamic LCE model. The numerical calculations show that coupled system has three steady synchronization modes: in-phase mode, anti-phase non-phase-locked mode more easily achieved than mode....
