【摘要】：变速箱的研制过程中,台架试验已成为不可或缺的一部分,为了降低企业的试验成本,研制与开发适合企业产品序列的试验台成为必然。结合企业的实际情况,研制一套能满足实际生产要求的疲劳试验台,包括试验台的总体方案设计、试验台的搭建、试验台的调试与运行等。在满足试验台运行要求外,试验台设计力求操作简单易维护。根据疲劳试验的特点,完成了疲劳试验台的总体方案设计,研究分析确定采用电封闭式结构。加载控制和驱动控制系统采用共直流母线结构,驱动电机工作在电动状态,加载电机工作在发电状态,设备消耗的电能只用来维持系统的工作条件和补偿机电损耗。所以试验台具有节能环保的特点。在研究分析企业变速箱结构特点的基础上,完成了试验台的机械部分设计。使试验台不仅能完成前置前驱的变速箱试验,还能完成前置后驱的变速箱试验,同时兼顾四驱变速箱试验的搭载。设计了以PLC、变频器和转速转矩传感器为核心的控制系统。通过PLC对变频器的控制,使试验台具备以下功能:手动试验和自动试验、正拖/反拖试验模式、变转速或变转矩的试验。基于LabVIEW图形化编程便捷的优点,开发了试验台的监控软件。通过工控机进行试验条件的设置和试验状态的实时监控,实现了数据采集、处理、存储及调用,并进行故障报警。
[Abstract]:In the process of development of gearbox, bench test has become an indispensable part. In order to reduce the test cost of the enterprise, it is inevitable to develop a test bed suitable for the enterprise product sequence. According to the actual situation of the enterprise, a set of fatigue test-bed which can meet the actual production requirements is developed, including the overall scheme design of the test-bed, the construction of the test-bed, the debugging and operation of the test-bed, etc. In order to meet the operational requirements of the test bed, the design of the test bed is simple and easy to maintain. According to the characteristics of fatigue test, the overall scheme design of fatigue test bench is completed, and the electric closed structure is adopted in the research and analysis. The load control and drive control system adopts the common DC bus structure, the driving motor works in the electric state, and the load motor works in the power generation state. The electric energy consumed by the equipment is only used to maintain the working conditions of the system and to compensate for the electromechanical loss. So the test bed has the characteristic of energy saving and environmental protection. Based on the study and analysis of the structural characteristics of the gearbox, the mechanical design of the test bench is completed. The test bench can not only finish the gearbox test of front drive, but also finish the gearbox test of pre- and post-drive, at the same time, the test of four-drive gearbox can be taken into account. A control system based on PLC, frequency converter and torque sensor is designed. Through the control of frequency converter by PLC, the test bench has the following functions: manual test and automatic test, forward towing / reverse towing test mode, variable speed or torque change test. Based on the advantages of LabVIEW graphical programming, the monitoring software of the test bench is developed. Through the setting of test conditions and the real-time monitoring of the test state, the data acquisition, processing, storage and transfer are realized, and the fault alarm is given.
