在实验和样机的基础上对搅拌物料进行受力分析和计算 ,求得每层搅拌叶片上的工作阻力矩。然后以搅拌功率最小为优化目标 ,对搅拌机的搅拌机构进行了优化设计和计算。 On the basis of experiment and prototype, the force analysis and calculation of mixing materials were carried out, and the working resistance moment on each mixing blade was obtained. Then, the minimum stirring power is the optimization goal, and the mixer’s stirring mechanism is optimized and calculated.
