摘　　要：船用内曲线径向球塞式低速大转矩液压马达转子体是液压马达动力输出的核心构件,转子体的结构设计不仅要满足结构静力学强度、刚度条件,也要满足一定的动态性能要求。通过ANSYS软件对其结构进行有限元分析,可以得到液压马达转子体的结构应力、形变量、固有频率、振型及相对位移分布。分析结果可作为转子体优化设计的参考数据,并结合样机试验验证,通过合理的机构优化使转子体避开共振频率区域,从而提高转子体的可靠性和使用寿命。Inner curve radial ball-style hydraulic motor rotor for marine is the core component of hydraulic motor power output. The structural design of the rotor not only satisfies the strength and stiffness conditions of structural static, but also meet certain dynamic performance requirements. Through the finite element analysis of its structure by ANSYS software, the structural stress, deformation, natural frequency, mode shape and relative displacement distribution of the rotor of the hydraulic motor can be obtained. The analysis results can be used as reference data for the optimal design of the rotor body, and combined with prototype test verification, the rotor body is avoided from the resonance frequency region through reasonable mechanism optimization, to improve the reliability and service life of the rotor body.
