摘要
Abstract
A test amplifying rod and pill mixing chamber and other auxiliary devices were designed and manufactured according to the requirements and characteristics of pneumatic auxiliary ultrasonic shot peening strengthening test .And then the feasibility of the new shot peening way was also verified .The maximum impact force of pellets was practically measured by pressure test system and a finite element simulation was processed to the course of a single pellet impacting by using software LS -DYNA.The simula-tion result of residual compressive stress and the theoretical ones were compared and analyzed ,which showed that the actual im-pact force of pellet was equal to the maximum impact force of simulation ,and the same change trend of the residual stress was ob-tained by the simulation and contact mechanics theory ,so the simulation results can be applied to preliminary forecast and analy-sis to ultrasonic shot peening .关键词
