液压元件试验台的精度是试验质量的关键指标,精度分析是试验台研制过程中必须进行的工作。现将我们在 ISO 标准 B 级精度 CAT 液压阀试验台的研制过程中所作的精度分析作一简要介绍。ISO 标准规定的液压试验的 B 级精度指标 The precision of the hydraulic component test rig is the key indicator of the quality of the test. The accuracy analysis is the work that must be carried out during the development of the test rig. Now we are in the ISO standard B-level CAT hydraulic valve test bench in the process of making the precision analysis made a brief introduction. ISO standard hydraulic test class B precision index
