摘　　要：传统摆线液压马达由于采用机械配流,造成机械损失和容积损失高,同时马达结构尺寸大,加工难度较高。基于此,研究一种采用高速电磁开关阀组实现数字式配流与调速一体化的摆线液压马达。分析数字式配流摆线液压马达运行机制与结构特点;在对摆线马达和电磁阀流量特性理论分析的基础上,建立阀-马达动力学模型,针对所提出的模型进行仿真;在此基础上研究摆线马达的配流与转向切换的特性,通过改变PWM占空比,摆线马达可以较好实现双向调速。相比于机械配流式摆线马达,数字式配流摆线马达结构复杂度大大降低,配流与调速的灵活性得到增强。In traditional orbit hydraulic motor,mechanical flow distribution is used,resulting in high mechanical and volume loss.At the same time,the motor has a large size and difficulty in processing.Based on this,a hydraulic motor that used a high-speed electromagnet valve group to achieve digital distribution and speed adjustment was studied.The operating mechanism and structural characteristics of the digital distributed hydraulic motor were analyzed;on the basis of the theoretical analysis of the orbit motor and the electromagnetic valve flow characteristics,a valve-motor dynamic model was established to simulate the proposed model;on the basis,the characteristics of the distribution and steering switching of the orbit motor were studied;by changing the PWM duty cycle,the orbit motor can better achieve two-way speed regulation.Compared with mechanical matching orbit motors,structural complexity of the orbit hydraulic motors with digital distribution has greatly reduced and the flexibility of streaming and speed adjustment is enhanced.
