【Abstract】 In this paper, a computation program based on a dynamic model about the small amplitude vibration mechanism of jolt molding machine is proposed, The interaction among dynamic changing of gas, im pact and vibration system is comprehensively considered in this model. In terms of an appointed step of time, this program can output calculating data. It follows that all the in formation of small amplitude jolt process is obtained during the course of the transitiona1 process of impact motion from st- arting to holding out stablization. The in formation is vibrating-iron coordinat- cs, vibrationg-iron velocity, gas-pressure, time througn transitional process, times of impact motion, period of vibration, rating-energy of impact and ind- icating-work diagram etc. The calculated values check well with the results of test. This program can be used to simulate both the normal impact motion and the non-normal impactmotion.更多还原
