低脉动液压马达凸轮环变形预补偿优化设计机构:1浙江大学,机械工程学院,流体动力与机电系统国家重点实验室,中国杭州,310027;2正时乐液压有限责任公司,中国秦皇岛,066000 目的:内曲线液压马达在重载工况下凸轮环与滚子接触产生的弹性变形,改变了预设的运行轨迹,使得马达产生较大的转速转矩脉动。本文提出一种凸轮环变形预补偿的优化设计方法,在设计阶段耦合弹性变形的影响,以降低马达在实际工作时的脉动,从而提高马达的稳定性。 创新点:1.通过赫兹接触理论和马达结构的受力分析,建立凸轮环弹性变形非均匀分布的计算方法;2.建立凸轮环弹性变形预补偿的设计方法,并通过实验进行验证。 方法:1.通过理论推导建立凸轮环非均匀弹性变形与工作压力之间的直接关系,基于此提出凸轮环弹性变形预补偿的设计方法,并给出完整的流程与计算方法。2.通过仿真模拟,对凸轮环变形计算进行验证,初步证明所提方法的正确性。3.通过实验验证,对在不同工况下,马达的脉动率进行分析,验证所提方法的有效性。 结论:1.提出凸轮环变形预补偿优化设计方法,包括初始的整体补偿和二次局部补偿。2.在对马达进行详细运动学和受力分析的基础上,推导出凸轮环变形的计算过程,并用有限元仿真方法进行实例验证。3.脉动降低率随着工作压力的增加而增加,并且在45 MPa工作压力下可以实现40%的高脉动降低率。 关键词组: Darkslateblue:Affiliate; Royal Blue:Author; Turquoise:Article
