Research on logarithmic spiral roll profile in hot rolling [PDF]
Metalurgija, 2022 Presented is a new logarithmic spiral roll profile for 2-high hot rolling,and successfully establishing the logarithmic spiral roll profile equation.The inherent benefits over traditional sine curve roll profile include control of rolling force and ...

A modified logarithmic spiral method for determining passive earth pressure
Journal of Rock Mechanics and Geotechnical Engineering, 2018 In this study, a modified logarithmic spiral method is proposed to determine the passive earth pressure and failure surface of cohesionless sloping backfill, with presence of wall–soil interface friction.

LOGARITHMIC SPIRAL LIGHT PIPE FOR SCINTILLATORS [PDF]
, 1960 A prccedure is described for designing and making logarithmic spiral light pipes which are to be used in coupling scintillators to photomultipliers in cases where the scintillator must be placed in a strong magnetic field. (C.J.G.)

Study on the Motion Law of Logarithmic Spiral Type Cam Mechanism
Jixie chuandong, 2015 The solid models of the logarithmic spiral cam mechanism and common cam mechanism are established by using SolidWorks,and the kinematics simulation is carried out.Then,by using the software of ANSYS / LS-DYNA,the dynamics analysis of the two kinds of cam

THE LOGARITHMIC SPIRAL AND ITS SPHERICAL COUNTERPART
Journal of Industrial Design and Engineering Graphics, 2019 Logarithmic spirals are isogonal trajectories of pencils of lines. From a series of geometric consequences, we pick out a few which are relevant for kinematics: When a logarithmic spiral rolls on a line, its asymptotic point traces a straight line. Hence,

Spiral Lambert's problem with generalized logarithmic spirals
, 2016 Lambert?s problem subject to a continuous acceleration is solved using the family of generalized logarithmic spirals. Thanks to the existence of two first integrals related to the energy and angular momentum surprising analogies with the Keplerian case are found. A minimum-energy spiral transfer exists.

Nihon Kikai Gakkai ronbunshu, 2022 To improve robot manipulability, force sensing for scissors is expected to be significant. In general scissors, the moment and the crossing angle of the blade depends on the cutting position, resulting in the difference of the required input force for ...

The Elliptic Logarithmic Spiral [PDF]
Nature, 1922 I AM much obliged to Mr. Wright for his correction (NATURE, July 8, p. 40). I had made a search in English and Continental books on curves and concluded that this spiral had been overlooked as a curve. But it appears to have been recognised in connexion with the spherical pendulum. Prof. Lamb in his “Dynamics,” p.
