The sampling device built experimental platform, the use of computer testing system, made ​​a lot of model validation experiments

In the preliminary design and manufacture of sampling device for the study, that the simulation platform, the establishment of the new sampling device simulation model. In order to verify the correctness of the simulation model, the authors of the sampling device built  Instrument valve manifolds  platform, the use of computer testing system, made ​​a lot of model validation experiments. Experimental results show that the authors constructed a  Valve manifold  model is correct, can be used as a basis for 2 way manifolds . Since the authenticity of systematic sampling of materials depends largely on the stability of the sampling rate of the car, so the author based on the simulation model, the process of reclaiming speed stability issues detailed study draws some important conclusions. Its main tasks are: Introduction to sampling system structure and working principle, a simulation model of the system, and using the model to analyze the sampling process speed load characteristics;
