【Abstract】 The mathematical model of momentum balance equation while dropping hammer impacting on the earth-moving vehicle is derived in this paper. The factors influencing the deformation of hammer have been found out and the strategies for the control of the deformation are discussed. The mathematical model for the relations between the hammer length after deformation and that before deformation at arbitrary time provides the theoretical foundation for the study of the plastic deformation of the dropping hammer.更多还原
