The effect of prismatic joint inertia on dynamics of planar kinematic chains with friction is investigated. The influence of the prismatic joint inertia on the position of the application point of the joint reaction forces and on the dynamic response of a planar robot arm with feedback control is analyzed. Larger values of the initial condition response characteristics are observed for larger v...

We study the effects of seismic coupling, friction, viscous, and inertia on earthquake nucleation based a two-body spring-slider model in presence thermal- pressurized slip-dependent friction viscosity. The stiffness ratio system to represent coupling is coil spring K between two sliders leaf L slider background plate denoted by s=K/L. s not significant factor generating phase. masses are m1 m2...

This paper introduces a way of reducing the torque variation in scroll compressors. In a scroll compressor where radial compliance device such as the slider bush is used for the flank sealing, the orbiting scroll member is given the freedom of movement in the radial direction. When such an orbiting scroll member orbits around the nonorbiting scroll member whose center is offset from that of the...

In this article present a new method for investigating the functionality of crank-slider mechanism given coefficient change in average speed slider and optimal transmission angle to ensure most outstanding transfer force from input link working element (output link). When implementing technological process оn crank presses, it is necessary provide predetermined cycle motion: fast lifting, dwell...

The presence of a predator affects prey populations either by direct predation or modifying various parts their life history. We investigated whether the hatching time, developmental stage, and body size at common frog ( Rana temporaria ) embryos would alter in red-eared slider Trachemys scripta elegans as predator. affected all factors examined. found that absence slider, hatched 12 days, whil...

The position accuracy of the bottom dead centre (BDC) a slider is crucial performance index to measure quality multi-link mechanical press. At present, research on improving BDC mainly focuses error compensation, and there lack tolerance design transmission mechanism according requirements BDC. In this paper, motion output press characterized by inclined angle slider. Based loop increment metho...

Introduction In recent years, thermal actuated flying height control has been implemented in Hard Disk Drives (HDD) to reduce the effect of flying height variations due to manufacturing tolerances or write current introduced pole tip protrusion (Fig. 1). A stable low flying height is necessary to achieve low bit error rates (BER) [1]. Thermal flying height control is used in a “static manner” i...
