[Abstract]:With the return of the real economy with the manufacturing industry as the main body, the quality of industrial products and technological innovation become the key to seize the commanding point of economic science and technology. The core of the development of modern manufacturing industry lies in the design, and the core of the mechanical design in the manufacturing industry lies in the organization. The mechanism provides the effective theory and method for the innovation and development of the machinery industry. The problem of synthesis and mobility of planar linkage mechanism has always been a heavy and difficult point in the study of mechanism. Based on the previous research results, this paper makes a more in-depth research on planar linkage mechanism. This paper attempts to obtain a more complete and practical comprehensive solution for the mechanism, and analyzes and studies the mobility problem of typical planar multi-bar mechanism. The main contents of this paper are as follows: we try to obtain a more complete and practical comprehensive solution of planar linkage mechanism.
