In this paper, a kineto-static analysis for an articulated six-wheeled rover called RobuRoc is investigated. A methodology based on reciprocal screw systems is developed for the kinematic modeling and analysis of such multi-monocycle like kinematic structure. A six dimensional force ellipsoid is introduced for the evaluation of traction performances.

Background: Abdominoplasty has consistently been one of the top cosmetic procedures performed each year with a high patient satisfaction rate. Excision excess abdominal skin shown to reduce low back pain and improve posture. The effects removal would, theoretically, be demonstrated through changes in gait. This study aimed measure kinematic differences during gait obtain objective measures for ...

Abstract The axle load acts on the box unit and has shock-pulse nature when car is moving, that can lead to a mutual change in surface positions of roller ends with edges bearing races. ways are proposed optimize internal geometry radial end contact elements unit. It eliminate occurrence possible conditions movement rollers into thrust locking by increasing minimum limit clearance box.
