Abstract: [Objective] In order to solve the problem that the end product of dairy industry is affected by the breakage of the straw,at the same time,it provides a reliable testing basis for straw inspection standards. [Method] The straw is struck by a weight of a certain mass falling from a fixed height,then observe the broken state of the impact site of the straw,study the impact resistance test method of straw,design a straw impact tester apply to detection. [Result] The test method of impact resistance of straws can be applied to the test of straws entering the factory,it can improve the detection efficiency,and it is an effective measure to monitor the quality of the straw to the factory.At the same time,it also realizes the number intelligence of the impact resistance test of the straw. [Conclusion] The research has high practicability,the use of straw impact tester can simplify the work flow and improve the detection efficiency. As an effective test method in the industry,it has great promotion value.
