【摘要】 为了达到碳纤维液压缸缸筒轻量化的目的并研究其是否满足强度与刚度要求，运用ANSYS软件中的ACP模块对缠绕层进行铺层角度方案设计，得出在90°铺层之间增加60°铺层更有利于CFRP缠绕层设计。采用ACP模块与实体建模仿真对所设计的缸筒进行应力与变形分析，得出仿真变形差值为5.4%,应力值差值为4.8%。由于这两种方式对铺层角度的仿真结果不同，导致各铺层间的应力最小相差6.31 MPa,最大相差40.27 MPa。为了使求解结果更加贴切实际缠绕操作，提出当采用温度场热应力等效初始缠绕张力时，应将各铺层缠绕过程中的初始应力与ACP仿真和实体建模仿真各铺层应力所产生的差值进行求和。通过该方法，温度场等效应力仿真的剩余应力与计算的剩余应力图形整体基本吻合，优于温度场等效初始缠绕应力仿真的剩余应力。最终，在满足强度与硬度的前提下，缸筒质量由设计前的11.469 kg减少至9.064 6 kg,减轻了20.96%,达到轻量化目的。更多还原

【Abstract】 In order to achieve the lightweight purpose of the carbon fiber hydraulic cylinder barrel and study whether it meets the requirements of strength and stiffness, the ACP module in ANSYS software was used to design the lay-up angle scheme of the winding layer.It is concluded that adding a 60° lay-up between 90° lay-ups is more conducive to the design of the CFRP winding layer.The stress and deformation of the designed cylinder barrel were analyzed by using the ACP module and solid modeling simulation.It is concluded that the simulation deformation difference is 5.4%,the stress value difference is 4.8%.Due to the different simulation results of the layup angle for these two methods, the minimum difference in stress between each layup is 6.31 MPa and the maximum difference is 40.27 MPa.In order to make the solution results more in line with the actual winding operation, it was proposed that when the equivalent initial winding tension of the thermal stress in the temperature field was adopted, the initial stress during the winding process of each layer should be summed up with the differences produced by ACP simulation and solid modeling simulation of the stress of each layer.Through this method, the residual stress in the equivalent stress simulation of the temperature field is basically consistent with the calculated residual stress graph as a whole, and is superior to the residual stress in the equivalent initial winding stress simulation of the temperature field.Ultimately, while meeting the requirements of strength and hardness, the mass of the cylinder barrel is reduced from 11.469 kg before the design to 9.064 6 kg, with a mass reduction of 20.96%,achieving the goal of lightweight.更多还原
