Study of the influence of shape on the strength characteristics of composite cylinders for compressed natural gas
Among alternative fuels, the leading position is occupied by gas-engine fuel due to its economy and environmental friendliness. The most promising, due to the low cost and availability, are compressed natural gases (CNG). The main problem is the placement and storage of gaseous fuel in cars. There are various versions of compressed natural gas cylinders. It is proposed to use cylinders of complex shape to solve the problem of placing the fuel reserve on Board the car. The properties of gas cylinders of various shapes are analyzed, and the most loaded elements are calculated in the COMPASS APM-FEM software package. The strength characteristics of gas cylinders of various shapes are determined by calculation and the possibility of their practical implementation is considered.
