چکیده

Thispaper describesthe fundamental physicalmotivationsfor small-scaleminimum surface-effect design,and presents a three degree-of-freedom micromanipulator design that incorporates a minimum surface.effect approach. The primary focus of the design is the split-tube flexure, a unique small-scale revolute joint that exhibits a considerably larger range of motion and significantly better multi-axis revolute joint characteristics than a conventional flexure. The development of this joint enables the implementation of a smaU-scale spatiallyloaded revolute joint-based manipulator with wellbehaved kinematic characteristics and without the backlash and stick-slip behavior that would otherwise prevent precision control.

A Six Degree of Freedom Micromanipulator for Opthalmic Surgery

Needs which have arisen in ophthalmic research have motivated the development of a six degree of freedom parallel micromanipulator. The first application of the tool will be in the treatment of retinal vemus occlusion, for which micron-scale spherical movement of a glass micropipette tip inside the eye is required. The initial speration mode will be open loop while future operation will be in a...

Seismic Design of Steel Structures Based on Ductility and Incremental Nonlinear Dynamic Analysis

In this paper a simple tool for seismic design of steel structures for a selected ductility level is presented. For this purpose, a consistent set of earthquakes is selected and sorted based on the maximum acceleration of ground surface. The selected records are applied as the base motion to a single-degree-of-freedom system with strain hardening and the maximum response acceleration is determi...

An Efficient Strain Based Cylindrical Shell Finite Element

The need for compatibility between degrees of freedom of various elements is a major problem encountered in practice during the modeling of complex structures; the problem is generally solved by an additional rotational degree of freedom [1-3]. This present paper investigates possible improvements to the performances of strain based cylindrical shell finite element [4] by introducing an additio...
