The software used to study the water lubrication performance of rubber is less and the function is not perfect at present.There are some shortcoming of the existing rubber water lubrication performance testing system,such that the complicated loading methods will cause all kinds of unpredictable results and lead to large consumption of rubber raw materials,and other attachments in the load structure will affect the size of the load.In order to meet the requirements of the experimental research on the performance of the water lubricated rubber,a rubber performance test system with Ltype loading mode based on LabVIEW was designed,and was used to research the water lubrication performance of nitrilebutadiene rubber (NBR).The experiment shows that this rubber water lubrication performance testing system has good system stability and can obtain reliable data,it is convenient for postmaintenance and adding function,and Ltype loading method has the advantages of simple structure,easy realization,low cost and saving raw materials.
