【摘要】：传统的液压马达试验台测试系统大多是针对通用工业液压马达或者工程机械上的液压马达而设计的，其面向的对象是高压低速或者低压高速液压马达，不能很好的满足高压高速液压马达性能测试需要。本课题针对某高压高速液压马达的试验需求，研制开发了液压试验台及基于Labview的性能测试系统。该系统能够在35MPa高压，12000r/min高速下进行该型液压马达各项型式试验项目和定期试验项目。本文在对国内外液压测试技术和液压马达试验台现状的调研分析的基础上，首先，针对该型高压高速液压马达的运行特点，即最高35MPa、12000r/min，正常21MPa、8800r/min的工作要求，对试验系统进行了详细分析，并在此基础上对液压系统和测试系统进行了总体设计。其次，详细阐述了液压系统的工作原理，包括油源和拖动部分、油温控制部分、换向部分、加载部分等。然后设计了测试系统的硬件组成并开发了基于Labview试验台测试软件系统。为了解决测试系统双输入双输出的控制稳定性问题、研究了基于神经网络的自适应PID算法，优化了控制特性。最后在本课题所开发的试验台上对该型液压马达进行了耐久试验、长期循环试验、脉冲试验等性能测试项目。试验验证，该系统功能和各项技术指标达到了设计要求，满足了工作需要。
[Abstract]:The traditional hydraulic motor test bench test system is mostly designed for general industrial hydraulic motor or hydraulic motor on construction machinery, and its target is high pressure low speed or low pressure high speed hydraulic motor. Can not meet the high pressure high speed hydraulic motor performance testing needs. This topic is aimed at a high pressure high speed hydraulic motor test requirements. The hydraulic test bench and the performance test system based on Labview are developed. The system can be used at 35MPa high pressure. All types of test items and periodic test items of this type hydraulic motor are carried out at high speed of 12000r / min. Based on the investigation and analysis of domestic and foreign hydraulic testing technology and hydraulic motor test bench, firstly, aiming at the operation characteristics of this type of high pressure and high speed hydraulic motor, that is, up to 35 MPA. A detailed analysis of the test system was made for 12000r / min, normal 21MPA / 8800rmin working requirements. On this basis, the hydraulic system and the test system are designed. Secondly, the working principle of the hydraulic system is described in detail, including the oil source and drag part, oil temperature control part, commutation part. Then the hardware structure of the test system is designed and the test software system based on Labview is developed. In order to solve the control stability problem of the test system with two inputs and two outputs. The adaptive PID algorithm based on neural network is studied, and the control characteristics are optimized. Finally, the durability test, long cycle test, pulse test and other performance tests of this type hydraulic motor are carried out on the test bench developed in this paper. The system functions and various technical specifications meet the design requirements and meet the needs of the work.
