Electrification of a Retractor Consisting of Flexible Structure and Development of Six-D.o.F Surgical Assist Arm with Unactuated Joints

Toshihiro Yukawa, Kazushi Nakamura, Hiroki Satoh, Youichi Takeda, Yoshiaki Oshida, Jun Sasaki

Abstract: In this paper, we describe a new type of a flexible retractor (universal fixator) and an assist arm with surgical instrument developed as substitutes for an abdominal retractor for use during surgery. The new assist arm as the retractor with surgical instrument can increase the efficiency of retraction function during surg [...] Read more.

Numerical investigation of System Ringing and Stress Oscillations in High Speed Tensile Test on Polymers

M.Nutini, D.Sinnone, M.Vitali

Abstract: The Finite Element (F.E.) analysis of a grip system of a servo hydraulic machine used for high speed tensile testing of polymers is here presented. State-of-the- art dynamometers use a slack adaptor to allow the machine to accelerate, in order to reach the nominal tensile speed before the load is applied, so that the entir [...] Read more.

Sloshing in compound cylindrically-conical reservoirs

Strelnikova E., Sirenko V., Gnitko V., Degtyarev K., Naumenko Yu.

Abstract: The issue of vibrations of fluid-filled compound shells is considered. The shell is supposed to be consisted of cylindrical and conical parts. The liquid is ideal and incompressible, and its motion is potential. The fluid pressure acting on the wetted shell surface is obtained from the linearized Bernoulli’s equation for a [...] Read more.

An active forming grinding method for cylindrical involute gears based on a second-order transmission error model

Gang Li

Abstract: An active form-grinding method is proposed to obtain excellent and stable contact performance of cylindrical gears by designing modification forms based on a predesigned controllable second-order transmission error function. First of all, a predesigned second-order transmission error polynomial function is assigned to the g [...] Read more.
