Design and Kinematic Analysis of the Car Jack

Car jack is the basic equipment of every car. To replace the tires or to repair a specific defect on the car it is necessary to have a car jack. A modern way of creating the complex mechanical structures is described in this paper, which allows for rapid change of parameters and therefore of the whole design, i.e. the parameterized car jack model was developed. Also, the goal of this research is to carry out kinematic analysis of a car jack design. Parametric model is developed in such a way that all parameters of design are in correlations to one main parameter. The angle of thread spindle is chosen for main parameter. Usually, main parameter should be chosen as one of the parameters from power input elements. Car jack has a human hand power which is applied on car jack handle and because of that, the angle of rotation of thread spindle is the best for main parameter.

Robot Hands

There has been a continuous effort by researchers to develop multi-fingered robot hands for variety of applications. Some of these hands are meant for industrial applications while thers are used for orthopedic rehabilitation of humans. However the degree of success to develop an anthropomorphic robot hand in close resemblence with a typical human hand has not been satisfactory. In the present work an attempt has been made to design a robot hand having five fingers with 25 degrees of freedom by closly following the anatomy of human hand.The kinematic analysis of the hand offers confirmative results for effective graspingand manipulating objects.

To study the functioning of the jaw apparatus of fish was developed and tested kinematic scheme using crank mechanism. This model is a modified analogue of the previously used four-link hinge system. In this development, based on empirical studies, was taken into account the immobility of the pterygoid and Palatine bones, which in previous works were considered as moving elements. The application of the analytical approach allowed to determine the dependence of the angles and links of the mechanism, as well as the kinematic characteristics of the upper and lower jaw blocks. The morphometric data of the jaw apparatus of two closely related species of coastal Cottoidei, characterized by linear parameters of bones, were used for the implementation of kinematic analysis. As a result of the study, it was found that the increase in the length of the jaws affects the space-time kinematic characteristics, changing the amplitude and speed of movement. It is shown that the angle of rotation and the angular velocity of the maxillary block decreases with the transition of views to the power of large objects, since the extension of the mouth becomes less relevant and is compensated by an increase in its size. At the same time, this provides an increase in the angle of rotation of the mandibular block and, accordingly, the maximum height of the mouth opening. In General, the resulting kinematic scheme and analytical dependences can be used to calculate the range of possible options and the speed of movements in different species of fish with a similar type of jaw apparatus.

Angle Of Rotation

The submitted paper presents a kinematic analysis of Stirling engine by the vector method. Position equations are written for various points of the mechanism, and values of velocity and acceleration are obtained from derivation of the equations, depending on time. Equations in matrix form are solved by means of the Matlab program. Graphic dependences of kinematic magnitudes of some points are given in dependence on the angle of rotation of the drive member. Position equations are utilised for the animation of the mechanism. The computational model of the Stirling engine was created in the SolidWorks software program.

Reconstructed Surfaces

In recent years there has been a trend in the structure determination of reconstructed surfaces to use high energy electron diffraction techniques, and to employ a kinematic approximation in analyzing the intensities of surface superlattice reflections. Experimentally this is motivated by the great success of the determination of the dimer adatom stacking fault (DAS) structure of the Si(111) 7 × 7 reconstructed surface.While in the case of transmission electron diffraction (TED) the validity of the kinematic approximation has been examined by using multislice calculations for Si and certain incident beam directions, far less has been done in the reflection high energy electron diffraction (RHEED) case. In this paper we aim to provide a thorough Bloch wave analysis of the various diffraction processes involved, and to set criteria on the validity for the kinematic analysis of the intensities of the surface superlattice reflections.The validity of the kinematic analysis, being common to both the TED and RHEED case, relies primarily on two underlying observations, namely (l)the surface superlattice scattering in the selvedge is kinematically dominating, and (2)the superlattice diffracted beams are uncoupled from the fundamental diffracted beams within the bulk.

Rapid Drop

Cells and tissues live on a number of dynamic metabolic pathways, which are made up of sequential enzymatic cascades.Recent biochemical and physiological studies of vision research showed the importance of cGMP metabolism in the rod outer segment of visual cell, indicat ing that the photon activated rhodopsin exerts activation effect on the GTP binding protein, transducin, and this act ivated transducin further activates phosphodiesterase (PDEase) to result in a rapid drop in cGMP concentration in the cytoplasm of rod outer segment. This rapid drop of cGMP concentration exerts to close the ion channel on the plasma membrane and to stop of inward current brings hyperpolarization and evokes an action potential.These sequential change of enzyme activities, known as cGMP cascade, proceeds quite rapidly within msec order. Such a rapid change of enzyme activities, such as PDEase in rod outer segment, was not a matter of conventional histochemical invest igations.
