Abstract：There are several loosenessproof construtions of piston rod end, such as the nut and lock pin, the double-nuts, the lock washer and U shape lock pawl in vibrating impact tamper. The nut structures are easily broken, loosened and teeth damaged in use. The vibrating impact lamper only works reliably for 70 h～80 h with the nut structures. If using U shape lock pawl, the vibrating impact lamper can work reliably more than 150 h, which is superior to organization standard. This structure improves the reliability compared with the structure with nut, but it raises the noise about 2 dB～3 dB, which exceeds the organization standard. How to lower the noise is a problem to be further researched.
