Abstract: Single-closed-loop N-bar mobility criteria are presented. These criteria provide a simple and effective method (1) to determine the full rotatability of any single closed-loop linkages, (2) to ...

Abstract: In this paper, the five-bar Grashof criterion is proposed and proved. A five-bar linkage is a Class I linkage if lmax + lmin 1 + lmin 1 ≤ m + n is satisfied, otherwise it is a Class ...

Abstract: This paper presents the concept and application of input joint rotation space of linkages and offers updates on the N-bar rotatability laws. A thorough discussion on the joint rotation space ...

Abstract: This paper presents a general theory to determine the sensitivity of tolerances to the performance quality of mechanisms and a technique to identify a robust design, which is the least sensitive ...

Abstract: A spherical joint must allow adequate mobility between the ball and socket. Unless the specific geometric requirement of the spherical joint, namely the trajectory of the ball stem in the ...

Abstract: A wide curve is a curve with width or cross section. This paper introduces a shape and size synthesis method for compliant mechanisms based on free-form wide curve theory. With the proposed ...

Abstract: This paper introduces the spanning tree theory to the topological synthesis of compliant mechanisms, in which spanning trees connect all the vertices together using a minimum number of edges. ...

Abstract: This paper presents a study on the higher-order motion of point-lines embedded on rigid bodies. The mathematic treatment of the paper is based on dual quaternion algebra and differential geometry ...

Abstract: A point-line is the combination of a directed line and an endpoint on the line. A pair of point-line positions corresponds to a point-line displacement, which is known to be associated with ...
