TL;DR: In this paper, the authors proposed a generalized transmission index for spatial mechanisms based on the virtual coefficient between the transmission wrench screw and the output twist screw, which is applicable to single-loop spatial linkages, with fixed output and single or multiple degrees of freedom.

TL;DR: In this paper, the reverse efficiency of the stabilizer is made different depending on a direction in which stabilizer force acts and the direction of the rebound direction, which can reduce the electric power required for maintaining the vehicle height in that direction.
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle stabilizer system having high practicality. SOLUTION: This vehicle stabilizer system 10 is equipped with a stabilizer bar and an actuator 32 which generates a stabilizer force which is a force for putting a wheel close to a vehicle body or separating them by rotating a stabilizer bar 28, and can perform vehicle height adjusting control by changing the stabilizer force. In the stabilizer system 10, the reverse efficiency of the actuator is made different depending on a direction in which the stabilizer force acts. In concrete, a pressure angle β between tooth surfaces of gears by which respective teeth of the two gears 58 and 60 of a reduction gear 42 which the actuator has are engaged and come into contact with is made different depending on a direction in which the stabilizer force acts. By this structure, the reverse efficiency of the actuator can be made low in one of the bound direction and the rebound direction. Since electric power required for maintaining the vehicle height in that direction is reduced, power saving is attained. COPYRIGHT: (C)2007,JPO&INPIT

TL;DR: In this paper, it was shown that the angle of obliquity of the oscillating force has a predominant effect on the energy dissipated at the contact and that no slip or dissipation would be expected if the line of action of the force lies within the cone of friction for the two surfaces.
Abstract: In a previous experimental investigation the author has shown that two spherical surfaces pressed together and subject to an oscillating tangential force, however small, exhibit microscopic interfacial slip which leads to energy dissipation and surface damage in the manner predicted theoretically by Mindlin. The analysis has been extended by Mindlin and Deresiewicz to include the effect of an oscillating force whose line of action lies at an oblique angle to the surface of contact. They show that the angle of obliquity of the oscillating force has a predominant effect on the energy dissipated at the contact and that no slip or dissipation would be expected if the line of action of the force lies within the cone of friction for the two surfaces.These conclusions have been the subject of the experimental investigation reported in this paper. The theoretical predictions are supported by the observations on almost all counts. Such discrepancies as occur are shown to be due to the inadequacy of the theoretical...
