The paper presents an analysis and validation method for a CAD model of a spur gear pumps series using FEM simulations. The analyzed pump is a new improved variant chosen among several constructive solutions created by parametric aided design in a range of gear pumps. Using mathematical computations and a calculus methodology there were identified the pressure values and forces generated in the pump assembly. The proposed study is especially applied to the gearing area and to the outlet chamber, where values and their variations are higher. FEM simulations are performed in these areas in order to identify and to present in a summary table the values of maximum stress, deformations and the percentages of calculation errors. The pump modelled and optimized by successive simulations led to the creation of an innovative gear pump series depending on the requirements imposed by the beneficiary.

“…Based on the assembly point of view, a product design evaluation was proposed by S. Katarina et.al in 2011 [7]. The innovative process design was used for Double gear pumps by C. Opran et.al in 2015 [8]. This diversification of customer requirements and the shortening of product life cycle have created a need for companies to manufacture and develop various types of products in a short-period of time [9] and development of new product is a creative and complex process, which is essentially arduous to improve and organize.…”

Innovations lead market. In today's computational and technocrat world, product development needs a prompt respond to accomplish market demands in short time and must be economically sustainable. Since the product design strongly affects the assembly process, it must be taken care at the initial stage which results in improving manufacturing process, saving assembly time and thereby cost. In this paper, an active approach to reduce the number of parts and thereby increasing design efficiency has been taken into consideration. Design for assembly (DFA) approach was applied to facilitate product structure without losing its standardization and functionality of product. Comparative analysis between, current and proposed design of refrigerator components like evaporator fan in freezing compartment and door hinge assembly are described out of the many sub assembly part reduction in total number of parts of refrigerator. Using DFA guidelines, we reduced total number of parts from 328 to 172, thereby leading to increase in design efficiency by more than 25%. The results obtained from the analysis leads to achieve our required expectations and can be further applied in manufacturing industries in order to improve the design efficiency.
