The invention discloses a test method for determining a recovery coefficient in metal material contact-impact. The test method includes the steps of S1, preparing test materials including a metal ball, a metal plate, a speed sensor and an acquisition card; S2, releasing the metal ball during the test to enable the metal ball to fall from a high position keeping a distance of H away from the metal plate, and enabling the speed sensor to acquire an acceleration value and an impact time value of the metal ball impacting the metal plate every time in a process that the metal ball impacts the metal plate at the first time and finally stops on the metal plate, wherein the acceleration value acquired at the ith time is recorded as ai, and the time value corresponding to the ai is recorded as ti; using the acquisition card for acquiring the acceleration values and the time values; S3, processing test data, namely S31, making a curve graph about acceleration changing along with time according to the acceleration values and the time values corresponding to the acceleration values; S32, sequentially obtaining deltati, Tn and T2n; S33, obtaining the recovery coefficient. The test method for determining the recovery coefficient in metal material contact-impact has the advantages that the test method is easy to operate and capable of obtaining the precise impact recovery coefficient by testing the acceleration changing along with the time in the metal material contact-impact process, so that measurement precision is improved.
