【摘要】：传统液压泵工作特性测试方法需大量的多工况测试数据,测试过程繁琐,且由于测试数据的离散性,难以获得准确的工作特性曲线。提出基于多元非线性回归模型的液压泵工作特性测试方法。该方法通过少量测试数据建立液压泵数学模型,预测其工作特性,并获得各工况下的特性曲线。对数学模型进行了分析,结果表明:应用该模型可将测试误差控制在0.1%以内。与传统测试方法相比,该方法可简化测试过程,提高测试效率和测试精度。
[Abstract]:The traditional testing method of hydraulic pump working characteristic needs a lot of multi-condition test data, the test process is tedious, and because of the discreteness of test data, It is difficult to obtain accurate working characteristic curve. A testing method of hydraulic pump working characteristic based on multivariate nonlinear regression model is proposed. The mathematical model of hydraulic pump is established by a small amount of test data, and its working characteristic is forecasted. The mathematical model is analyzed. The results show that the test error can be controlled within 0.1% by using the model. Compared with the traditional test method, this method can simplify the testing process. Improve testing efficiency and accuracy.
