The Chinese government attaches great importance to the power battery industry and has formulated a series of related policies. To conduct policy characteristics analysis, we analysed 188 policy texts on China''s power battery industry issued on a national level from 1999 to 2020. We adopted a product life cycle perspective that combined four dimensions: …

This paper investigates the dynamic response of the cracked and flexible connecting rod in a slider-crank mechanism. Using Euler–Bernoulli beam theory to model the connecting rod without a crack, the governing equation and boundary conditions of the rod''s transverse vibration are derived through Hamilton''s principle. The moving boundary constraint …
Hierapolis sawmill schematic. A connecting rod crank has been found in the Celtic Oppida at Paule in Brittany, dated to 69BC [6]. The predecessor to the connecting length is the mechanical linkage used by Roman-era watermills.An early example of this linkage has been found at the late 3rd century Hierapolis sawmill in Roman Asia (modern Turkey) and the 6th century saw mills at …
The partial differential equation of motion of the flexible connecting rod of a slider crank is derived, under the assumption of small deflections. Application of the Galerkin procedure, leads to a system of linear ordinary differential equations, with respect to the modal coordinates of vibration of the rod. For periodic solutions, the foregoing system reduces to a system of …
This work bespeaks an insight into a real imperfect multibody systems synthesis, wherein the flexible behaviour of its components is considered. Based on the end-effector mechanism velocity, acceleration and defined transversal deflection for a flexible component, the mechanism optimal design variables have been investigated. Subsequently, the three …
