车载70 MPa Ⅳ型储氢气瓶设计与建模参数研究
Design and Modeling Parameters Research of Vehicle-mounted 70 MPa Type Ⅳ Hydrogen Storage Cylinder
摘要
Abstract
By taking a 70 MPa type Ⅳ hydrogen storage cylinder as the research object,the preliminary design and strength check of composite material layers were carried out in accordance with the netting theory.Based on the WCM module in ABAQUS,a refined modeling method was adopted to complete the finite element modeling of composite materials with variable angles and variable thicknesses in the head section.The failure of fibers in the composite material's winding layer of the cylinder under the minimum design burst pressure and the theoretical design burst pressure was analyzed.To further opti-mize the fiber failure problem,the effects of the start-up type of the composite material's winding layer,the number of hole expansions,the innermost winding type of the composite material's winding layer,and the initial stacking angle of the hoop winding layer on fiber failure were studied,and the composite material lay-up was optimized.The simulation results show that the lay-up scheme can meet the re-quirements of the minimum design burst pressure.关键词
