【摘要】 舵机电液伺服调节器试验台是在产品开发过程中,测试电液伺服调节器样机动静态性能,验证理论分析和计算机仿真结果正确性的必备设备,本文以船用舵机电液伺服调节器为被试对象,设计并搭建了CAT试验台,进行了相关研究。目前在国内外还没有针对船用舵机电液伺服调节器的试验标准,本文首先根据船用舵机电液伺服调节器的工作原理,参照液压伺服系统的测试原理和方法确定了相应的试验项目和方法;然后完成了试验台的整体方案设计和硬件搭建;CAT软件利用Visual Basic为开发工具,分模块设计了CAT软件系统。论文从硬件和软件两方面分析了系统误差的来源,针对试验现场提出了多种硬件和软件的抗干扰措施,提高了本CAT系统的稳定性、可靠性和测试精度;最后对研制的初样机进行了现场试验,得出试验结果,并对试验结果进行了相应的分析。本CAT试验台现已投入运行,完成了舵机电液伺服调节器初样机的动、静态性能测试,实现了试验大纲拟定的项目测试。运行表明,本CAT试验台操作方便,安全可靠,功能齐全,技术方案经济合理,具有良好的通用性和可拓展性;不仅可以满足船用舵机电液伺服调节器出厂试验的要求,也提供了进行科学研究、探讨性能改进的手段。同时本文介绍的CAT系统的设计思想和提高测试精度、稳定性和可靠性的措施,以及数据处理方法都有一定的通用性和实用价值。更多还原

【Abstract】 The CAT Test-bed Used in Electro-hydraulic Servo Regulator for Ship’s Rudder is an essential equipment to test the dynamic and static performance and confirm the analysis depended on theory and the computer simulation during the process of developing a new product. This paper is about the researching and producing of The CAT Test-bed Used in Electro-hydraulic Servo Regulator for Ship’s Rudder.At present, there is no standard for testing CAT Test-bed Used in Electro-hydraulic Servo Regulator for Ship’s Rudder. In this paper, it firstly ascertained the testing project and the way to test it according to the working principle of CAT Test-bed Used in Electro-hydraulic Servo Regulator for Ship’s Rudder and the testing principle of Electro-hydraulic Servo system. Then it completed the overall design and the hardware building. The CAT test-bed’s software system is designed by Visual Basic, which includes several models. This paper analyses the error resource from both software factors and hardware factors, provides several ways to resist the disturbing referring to the special condition of the testing environment which has advance in its stability, reliability and precision, in the end, using the sample we have done some experiment, obtaining the result, and analyze it.This CAT test-bed is on working now. It has completed the dynamic and static test on electro-hydraulic servo regulator achieving the program test listed on the experimental program. The result indicated that this CAT test-bed is ease of operation, safe, reliable with complete function and reasonable technology plan and economic,. At the same time, it provides a good general and expansive performance. It can not only achieve the Electro- hydraulic Servo Regulator for Ship’s Rudder’s level of leaving the factory, but also provide the way to research and promote its performance. At the same time, the idea to conceive a CAT system and the way to promote the testing precise, stability, and reliability and the data processing method introduced in this paper has general performance and practical value to some extent.更多还原
