摘　　要：为研究多制动器工作时的同步性能,以多卷筒提升装备液压制动系统为研究对象,采用SimHydraulics对制动系统进行建模仿真,分析油液管路长度、内径对多制动器同步性工作的影响。研究结果表明,油液管路长度越短,内径越小,制动器开闸响应时间越快,油液管路长度越短,内径越大,合闸响应时间越快。对不同油液管路长度和内径进行合理配置,可使制动器实现良好的同步性;在主路管径78 mm及主路长度10000 mm参数配置下,制动过程中的油压波动值满足行业标准对液压系统二级制动的参数要求;为多卷筒的液压制动系统设计提供参考。In order to study the synchronization performance of multiple brakes,the hydraulic braking system of the multi-reel hoisting equipment is taken as the research object.SimHydraulics is used to model and simulate the braking system and the influence of the length and inner diameter of the oil pipe on the synchronous operation of the multi-brake is studied.The results show that the shorter the length of oil pipeline,the smaller the diameter,the faster the brake opening response time,the shorter the length of oil pipeline,the larger the diameter,the faster the closing response time.The reasonable configuration of different oil pipeline lengths and inner diameters can make the brake achieve good synchronization.Under the main pipe diameter of 78 mm and main road length of 10000 mm parameter configuration,the oil pressure fluctuation value in the braking process meets the parameter requirements of the industry standard for the two-stage hydraulic system braking.It provides reference for the design of multi-reel hydraulic braking system.
