A wheeled mobile mechanism with a passive and/or active linkage mechanism for traveling in the outdoor environment is developed and evaluated. In our previous research, we developed a wheeled mobile robot which has six wheels and a passive linkage mechanism, and its maneuverability was experimentally verified. The ability to climb over a 0.20 [m] high bump, which is twice height of the wheel di...

The use of a fuzzy logic controller for an active suspension system on a wheeled vehicle is investigated. Addressing the opposing goals of ride quality and bump stop avoidance are integrated into one control algorithm. Construction of the fuzzy rules base will be discussed comprehensively along with the membership function setup for both the input and output variables. Numerous quarter-car simu...

The method of investigation the non-linear vibrations wheel vehicles with guided cushioning system has been developed. It is based on idea perturbation methods combined theory special periodic Atebfunctions. All these made possible to obtain analytical relations, which describe characteristic features area vibrations. These relations can be basis for creation software product purpose minimize d...

In this paper a result on attitude tracking control of a micro satellite by integrator backstepping based on quaternion feedback is presented, and the controller is shown to render the system equilibrium point UGAS by application of the LaSalle-Yoshizawa theorem. This is a part of a study of possible control methods for the spacecraft ESEO, a spacecraft included in the SSETI project initiated b...

continuous stirred tank reactor (cstr) has particular importance in chemical industry. cstr has usually a nonlinear behavior which makes it difficult to control. the reactor has two parameters: the concentration and temperature of mixture both of which are uncertain. this case of cstr has large disturbance in domain. in order for disturbance rejection, a controller has to be designed. in this p...

Automobile wheels are an essential and important part of any automobile from their invention to today they have taken on various designs changes, structures, styles. Main function is carry the overall weight vehicle, resist forces & stresses created during driving transmit torque achieve required speed while driving. Wheels must well strength stiffness having durable design withstand runnin...

In this work, we aim at constructing numerical schemes, that are as efficient possible in terms of cost and conservation invariants, for the Vlasov--Fokker--Planck system coupled with Poisson or Amp\`ere equation. Splitting methods used where linear space treated by spectral semi-Lagrangian nonlinear diffusion velocity collision operator is using a stabilized Runge--Kutta--Chebyshev (RKC) integ...

The sign value of the first potter's wheels used in southern Levant (second half 5th mill. BC) is explored through production modalities V-shaped bowls, main category vessels shaped on wheel at that time. To this end, a morphometric approach applied to bowls from four sites numerical methods available Pottery 3-D software extract shape parameters. results obtained highlight high variability abs...

The THOR-05F is a new anthropomorphic test device with many notable features, including a biofidelic neck design with built-in lordosis that segregates load paths within the cervical spine. Static air bag deployment tests were carried out with the dummy positioned in the NHTSA-1 (chin on module) driver Out-Of-Position (OOP) configuration. A set of latemodel two-stage air bag modules were used i...

In this paper, modeling and simulation of nonlinear, Half-car Active Vehicle Suspension System (HAVSS) reinforced with PID controller is presented. The model has 4 degrees of freedom; comprising of heave movements of the front and rear axle, pitch and heave motions of the unsprung mass of the vehicle. The vehicle is excited by a triangular bump on an otherwise smooth road. The objective of the ...
