Abstract: It is very important to cultivate the students ability to analyze and solve problems during the teaching process.Combining with acceleration sensor and mechanical sensor,the oblique impact experiment device is constructed.Through the diagonal bar at different angles of inclination and impact block impact,it can be measured under different conditions generated by the acceleration and mechanical signals.The impacting data is collected and stored through the Labview software,analyze and display through matlab software.Through this test,it will deepen the students understanding of the phenomenon of collision.
