提高水力机械模型效率试验精度方法探讨

摘要

在总结中国水利水电科学研究院水力机械模型试验台提高水轮机某些试验精度方法的基础上，根据对测试误差的来源分析，从完善测试设备原位标定系统和方法、减小标定误差及减小随机误差等3个方面提出了提高试验精度的措施方法。%Based on the summary of some successful methods to improve the test accuracy of model tur-bine at the hydraulic machinery test station of China Institute of Water Resources and Hydropower Re-search, some useful methods are put forward to improve the test precision according to the analysis of the sources of measurement error. These methods include three aspects to perfect:the calibration systems of test equipments,reduce the calibration error and decrease the random error.
