The nonlinear contact force between gears and bearings exhibits intricate dynamics. This paper focuses on the coupling relationship time-varying meshing parameters of gears, dynamic backlash, bearing clearance in gear-bearing transmission systems. A model a system considering is established. mechanism stiffness, gear clearance, vibration response systems analyzed. results demonstrate negative correlation gears’ geometric center distance stiffness amplitude. Gear can affect relative position...
In a dynamic wireless power transfer (DWPT) system for electric vehicles, bipolar transmitting rail is often implemented to improve the misalignment tolerance, but its constraint lies in fluctuating output. This problem can be mitigated by applying two-phase receivers which, due structural characteristics impedance matching circuit, bring two new problems: limited range of and low efficiency. paper aims tackle problems introducing cascaded topology control method. Firstly, conventional...
Affine formation control of multiagent systems has recently received increasing attention in various applications. The distributed these agents, under single integrator dynamics, relies on the observations relative positions neighboring which when unavailable is detrimental to mission. In this paper, we propose an adaptive fusion estimator intermittent and consecutive observation loss settings. A affine localization (RAL) solution developed by exploiting geometry formation, then embedded...
Affine formation control is a subset of methods, which has gained increasing popularity for its flexibility and maneuverability in diverse applications. inherently distributed nature, where the local controllers onboard each agent are linearly dependent on relative position measurements neighboring agents. The unavailability these practice, due to node failure or missing links, leads change underlying graph topology, subsequently causes instability sub-optimal performance. In this paper, we...
According to the postulate of relativity in theory, a flash emits from light source uniformly moving car and returns after being reflected by mirror on roof. The person inside thinks that along vertical line, outside curve. time taken two paths is inconsistent. Now, this experiment has proved, interpretation traveling inconsistent with facts. not affected any inertial framem, will move car. Light does belong reference frame, nor frame. different objects. In absence experimental evidence,...
Consensus control of multiagent systems arises in various robotic applications such as rendezvous and formation control. For example, to compute the inputs individual agents, difference positions aligned coordinate frames i.e., pairwise displacements are typically measured. However, local might be subject rotational ambiguities, a rotation or reflection, particularly if agent not directly observed but reconstructed from e.g. Euclidean distances. This ambiguity causes stability issues...
Matter and energy are made up of the same basic particles. Why, then, is there a significant difference between matter energy? This because their particle compositions differ. The unit mass energy. Mass conservations essentially conversions. vector, moving at maximum velocity universe; however, after substance tangibly solidifies, this becomes zero. object is, thus, ratio particles contributing to those mass, direction its determined by directions. Electrons, photons, neutrons, protons,...
Along with increase of the fluid parameters for high-performance rotating machinery, induced force seals signally influenced rotor system. In this paper, it mainly presents effect on rotor-bearing-seal system, and nonlinear dynamic functions rotor-seal system are obtained Capone oil-film model Muszynska fluid-induced model. The characteristics at different analyzed by periodical responses, Poincaré maps, frequency spectrums charts, bifurcation etc. abundant behaviors revealed effects.
Einstein's principle of relativity is an important fundamental relativity. It can also be said that based on the assumption This represented by a diagram "relativity time interval", as shown in Fig.  . According to theory relativity, flash emits from light source moving car and returns after being reflected mirror roof. The person train thinks along vertical line, off AMB  curve. taken two routes inconsistent. In fact, it preconception. Einstein...
This article has demonstrated the possibility of deriving an equivalent mathematical velocity expression while setting aside concepts displacement and time. The proposed formula, better aligned with reality, allows a understanding equivalence matter energy, which are comprised same type basic particles. Why, then, is there significant difference between energy? because combination particles not same. Basic unit mass meaning energy conservations essentially conservation these Electrons,...
