The Design And Research Of Adsorbed Natural Gas Storage Device For Vehicle Based On QFD And TRIZ

With the continuous development of our national economy, the possession of the vehicle in our country is sharply increasing year by year. Although the number of vehicle growing provides people more convenience, it also brings some negative problems. Firstly, the vehicle's main fuel is gasoline, whose emissions lead to more and more serious pollution to our environment. Secondly, because of the oil reserves decrease, the price of gasoline is always soaring, which imposes more burden on people who use the vehicle. Comparing to the gasoline, natural gas's prices is cheaper, and brings less environmental pollution. Therefore, the development of natural gas storage system for vehicle and replacing gasoline as vehicle fuel gas will bring great economic benefits and environmental benefits.Through comparing and analyzing compressed natural gas, liquefied natural gas and adsorped natural gas three storage solutions, found absorbed natural gas is the best storage solutions which characterized by enough adsorption, low pressure and so on compared with the other two ways. But at present natural gas adsorption storage device mostly still use ordinary compressed natural gas cylinder, which can't solve some disadvantages of adsorption natural gas as fuel for vehicles, limiting in the development of the adsorption natural gas to vehicles.In order to develop a new adsorption natural gas storage device for vehicle, the Quality Function Deployment (QFD) and the Theory of Inventive Problem Solving (TRIZ) design methods are introduced in this paper. QFD technology is a kind of management-type design method to meet customer demand, which taking improvement of product quality and market competitiveness as goals. Its design concept is the use of standardized house of quality analysis model to rely on, successively in the concept design requirement analysis, quality development, development, technology development and parts production planning several stages of the design management, in order to make products to one-off design success. The innovation of the product cannot leave the generation of contradiction. QFD can guide the design process, but can't solve various contradictions problems in the design process, While TRIZ is one innovative design method, which based on defining, analyzing and solving contradiction to realize innovative design Two methods each have their advantages and disadvantages, integration of their advantages in product design is one hot research branch of modern concept design theory and method.In this paper, based on combining the merits of the two methods, product concept design model integrated QFD and TRIZ is put forward. Use this design model to control the quality of product design, to guide product robustness and innovative guide design process. Based on this concept design model, establish solid model of natural gas reserve devices by using3D entity modeling software, and conduct finite element analysis on this solid model to determine properties can be satisfied.
