摘　　要：鉴于我国煤矿成套采掘装备研发设计没有试验验证平台的现状,针对煤矿井下实际工作环境,在地面上建立1∶1的高端综采成套装备试验平台,重点研究探讨了采煤机和刨煤机成套装备关键力学参数测试平台建设方案,并对其理论与关键技术进行研究。该平台可实现液压拉杆拉力、摇臂关键截面应力应变、滚筒转矩、链轮振动特性、刮板输送机力学参数、刨煤机效率、刨煤机工作功率等参数的测试。通过以采煤机截割部振动特性测试结果为例,对其与截割特性间关系进行研究;并以26号液压支架测试结果为例,对其工况特性进行评价。结果表明,高端综采成套装备试验平台测试结果可靠,可实时处理综采成套装备性能参数和结构参数,以提高综采装备工作性能,并为综采成套设备提供设计、制造、检验技术支撑。In order to fill in a blank of no test verification platform applied to the development and design on the complete fully-mechanized mining and excavation equipments in China coal mine, according to the real working environment in the underground coal mine, a 1 ： 1 scale test platform of the complete advance fully-mechanized mining equipment was established on the surface ground. The paper stressed the study and discussion on the test platform construction plan of the key mechanics parameters for the complete equipment of the coal shearer and coal plough and had a study on the theory and key technology. The platform could realize the test and measurements on the tension of the hydraulie pull rod, the stress and train on the key cross sections of the ranging arm, the torque of the cutting drum, the vibration features of the sprocket, the mechanics parameters of the scraper eonveyor, the efficiency of the coal plough, the working power of the coal plough and other parameters. With the test results of vibration features for the cutting unit of the coal shearer as the example, a study was conducted on the relationship between the cutting features. With the test results of No. 26 hydraulic powered support, an evaluation was conducted on the performance features. The results showed that the test platform results of the advance and complete fullymechanized coal mining equipment were reliable and could timely handle the performance parameters and structure parameters of the complete fully-mechanized mining equipment in order to improve the working performances of the fully-mechanized equipment and to provide the design, manufacturing and inspection technology support to the complete fully-mechanized mining equipment.
