摘要
根据锤式破碎机的工作情况,提出了锤式破碎机冲击破煤的机理,采用Pro/E软件建立了PCM400型锤式破碎机执行部分三维虚拟装配模型,得到了其转动惯量。在此基础上对PCM400型锤式破碎机执行部分的冲击破煤过程进行了动态仿真,得到了在冲击破碎过程中PCM400锤式破碎机锤轴速度、加速度的变化规律。PCM400破碎机冲击破碎时,其速度变化率为0.63%,加速度变化率为1.26%,可以对现有的PCM400锤式破碎机进行优化设计。
According to the operation performance of the hammer crusher,the paper provided the impact coal crushing mechanism of the hammer crusher.The 3D virtual assembling model of the operation part for the PCM400 hammer crusher was established with the Pro/E software.The rotational inertia of the hammer crusher was obtained.Based on the above,a dynamic simulation on the impact crushing processing of the operation part for the PCM400 hammer crusher was conducted.The hammer shaft speed and the accelerated speed vari...
