Hydraulic fracturing requires a large volume of fresh water which is difficult and expensive to obtain in the desert area such as Tarim Basin. Currently flowback fluid is typically transported to the sewage treatment plant and then discharged after reaching environmental requirements however this is not only costly but also a waste of water resource. Therefore it is imperative to

In order to expand the range of activities of an excavator attachments such as hydraulic breakers have been developed to be applied to buckets. However it is very difficult to predict the dynamic behavior of hydraulic impact devices such as breakers because of high nonlinearity. Thus the purpose of this study is to optimie the impact performance of hydraulic breakers. The ultimate goal
