Recent development on innovation design of reconfigurable mechanisms in China

Abstract

Reconfigurable mechanisms can deliberately reconfigure themselves by rearranging the connectivity of components to meet the different requirements of tasks. Metamorphic and origami-derived mechanisms are two kinds of typical reconfigurable mechanisms, which have attracted increasing attention in the field of mechanisms since they were proposed. Improving the independent design level, innovation, and international competitive powers of reconfigurable mechanical products is important. Summarizing related significant innovation research and application achievements periodically will shed light on research directions and promote academic exchanges. This paper presents an overview of recent developments in innovation design of reconfigurable mechanisms in China, including metamorphic and origami mechanisms and their typical applications. The future development trends are analyzed and forecasted.

Analysis of Mechanical Fault Diagnosis Method According to Signal Deep Autoencoder

“…(2) Where, f and g are the activation functions of the encoding and decoding networks, w (1) and w (2) are the connection weights of the encoding and decoding networks, and b (1) and b (2) are the biasing of the encoding and decoding networks.…”

“…With the rapid development of science and technology and the upgrading of traditional industries, modern industrial systems have been developing towards the direction of large-scale complexity, and mechanical equipment has also grown in scale, sophisticated structures, diverse functions, and intelligent systems [1,2]. Mechanical equipment plays a key role in the modern industrial system.…”

Structure design and kinematic performance of the deployable translational parallel tape-spring manipulator

“…The deployable manipulator has the characteristics of small installation space and large workspace, which has great application prospects in small unmanned platforms such as satellites, unmanned aerial vehicles, and unmanned vehicles. Deployable mechanisms [1][2][3][4][5][6][7][8] can be folded into a small configuration for storage and expanded to a much larger structure for operation. Meanwhile, parallel manipulators such as DELTA [9], the Tricept robot [10], translational parallel manipulators [11][12][13][14][15], and spherical parallel manipulators [16][17][18][19] have parallel structures that improve the stiffness and accuracy of the manipulator [20,21].…”
