摘　　要：盾构机多马达同步驱动对液压马达的输出一致性要求较高。在盾构机维保或者再制造过程中,为了准确测试和评估多个新旧马达在载荷模拟加载环境下的输出一致性,基于6 m级常规液驱盾构主驱动结构,提出了一种适用于载荷模拟加载条件下的多马达一致性试验方法;通过搭建仿真分析模型对该试验方法进行验证,并建立了相应的多马达驱动一致性试验平台;在该试验平台上进行了多马达驱动一致性测试,并对比分析了各个参数如压力、流量、输出扭矩以及容积效率等方面的表现。结果显示:驱动马达在这些方面都表现出非常好的一致性。The multi-motor synchronous drive of the shield machine imposes stringent demands on the hydraulic motor′s output consistency.In order to accurately assess and evaluate the output consistency of multiple new and old motors under load simulation conditions during maintenance or remanufacturing processes,a novel method for testing multi-motor consistency suitable for load simulation loading environments is proposed based on the main drive structure of a 6 m conventional hydraulic shield.The effectiveness of this test method is verified through the construction of a simulation analysis model,leading to the establishment of a corresponding multi-motor drive consistency test platform.Subsequently,comprehensive performance parameters including pressure,flow rate,output torque,and volumetric efficiency are compared and analyzed during the multi-motor drive consistency tests conducted on this platform.The results demonstrate excellent consistency in these aspects for the drive motors.
