%X In this paper, a new solid particle erosion test experiment system , which is driven by shock wave and equipped with the dynamic pressure sensor and high-speed photography, is proposed. This test system has significant advantages over commonly used test apparatuses, e.g. less interference between attacking particles and rebounding ones, higher precision in mass measurement. In addition, this system is simple in structure and operation. High mach number of shock wave (e.g. 2.3) and high particle velocity (above 200 m/s) are obtained in this system. Consequently, different particle, various materials and surface treatment of specimens under 15~90° angle of impact can be tested in this system. An experiment using SiO2 particle to impact the mild steel is conducted and the obtained data confirmed the veracity of this test apparatus. This new test apparatus has promising application in optimization design and lifetime prediction for equipments eroded by solid particle erosion.
