摘　　要：中量级强冲击试验机的摆锤部分是整个实验机的核心,它的品质将决定整个试验的质量,在很大程度上也决定了整个试验机的使用寿命。因此,对其进行优化便势在必行。将中量级强冲击试验机摆锤部分进行结构简化,得出摆锤部分若干个典型的参数,以转动中心转轴所受冲量为研究对象,列出各参数与转动中心转轴所受冲量之间的关系式。应用MATLAB软件计算对应的结果。根据得出的数据,对试验机摆锤部分进行优化设计,从而达到减少转动中心转轴磨损,提高摆锤使用可靠性与寿命的目的。The pendulum is the most important part of the high impact shock testing machine with middleweight,whose quality will determine the whole experiment. The pendulum also determines the service time of the test machine. So it is imperative to optimize the pendulum of the test machine. The pendulum of the impact test machine is simplified,and some typical parameters are obtained. Taking the impluse of the rotation shaft as the object,the relationship between typical parameters and the impulse of the rotation shaft can be deduced. With the calculated data with MATLAB software,the optimal design of the pendulum is performed to minimize the shaft wear. thus the reliability and service life of the pendulum will be improved.
