某大型圆柱壳体横摇模拟装置系统建模与仿真

摘要

在国内首次以大体积、大排水量的某大型圆柱壳体为对象，针对在实验室条件下以大角度进行强迫横摇的试验要求，设计多组并联液压驱动横摇装置。为使系统易于实现，减小系统功率，提出一种逐步加载的驱动方式，以达到圆柱壳体实现大角度强迫横摇的要求；针对横摇装置液压控制系统，对壳体进行横摇过程中的受力分析，建立系统的数学模型，通过仿真研究验证模型的正确性。%Accordingtothetestrequirementsofrollinganalogdeviceofacylindricalshellunder laboratory conditions. To accomplish goals, put forward progressive loading large mode, and design the multigroup parallel rolling device based on hydraulic to achieve the requirement of rolling with large angle. According to the hydraulic control system, stress analysis to the cylindrical shell and the establishment of mathematical models, simulation research validates the effectiveness.
