Optimal Implementation

A mechanical design “compiler” has been developed which, given an appropriate schematic, specifications, and utility function for a mechanical design, returns catalog numbers for an optimal implementation. The compiler has been successfully tested on a variety of mechanical and hydraulic power transmission designs, and a few temperature sensing designs. Times required have been at worst proportional to the logarithm of the number of possible combinations of catalog numbers.

Pipe Joints

Hydraulic machinery suffers from the disadvantage of leakage of the fluid. Faulty pipe joints are one of the main offenders in this respect. In this paper the author describes some tests, carried out on a variety of pipe joints, to find a satisfactory one. In the absence of quantitative data, a joint and joint-ring were designed from the results of the tests. It is hoped that this paper will stimulate interest in this subject and so lead eventually to a wider knowledge and greater efficiency.

Abstract This paper introduces the theory underlying a computer program that takes as input a schematic of a mechanical or hydraulic power transmission system, plus specifications and a utility function, and returns catalog numbers from predefined catalogs for the optimal selection of components implementing the design. Unlike programs for designing single components or systems, this program provides the designer with a high level “language“ in which to compose new designs. It then performs much of the detailed design process. The process of “compilation”, or transformation from a high to a low level description, is based on a formalization of quantitative inferences about hierarchically organized sets of artifacts and operating conditions. This allows design compilation without the exhaustive enumeration of alternatives. The paper introduces the formalism, illustrating its use with examples. It then outlines some differences from previous work, and summarizes early tests and conclusions.

Hydraulic power transmission has been successfully applied to most forms of dredger. Suction dredgers employ hydraulics to position the suction tube, cutter dredgers have hydraulic motors fitted to the cutter drive, and bucket dredgers have hydraulic drive to the bucket chain. In addition, hydraulics is used to power winches and capstans, and to provide remote control of various valves and doors. Other common applications found in all types of vessel are hydraulic steering gear and, more recently, reversible bow propulsion gear. The advantages of hydraulic drive over comparable electric drives are numerous but operators are conservative. Greater realization of the benefits of hydraulic power transmission will result in more development and substantial economies.

Coupling systems play a vital role in hydraulic power transmission equipment. In recent years, flat-face coupling systems have been extensively studied due to their environment friendly features. The difficulty of the connection process of hydraulic equipment increases with the increase in their working pressure. To improve the convenience of making high-pressure connections, a novel flat-face coupling system is proposed in this article. In the proposed design, which is based on the conventional flat-face coupling system, the resistance caused by high hydraulic fluid pressure during coupling is drastically reduced by the addition of an instantaneous pressure relief module. In this study, the theoretical model of the system kinetics is established to illustrate the operational mechanism of the novel design, and a series of computational fluid dynamics numerical investigations based on the novel dynamic mesh technology and Ansys Mosaic meshing technology are implemented to verify the rationality of the proposed design. Additionally, an optimal design of the novel flat-face coupling system is proposed to reduce the energy loss during hydraulic power transmission.
