摘　　要：对反击式破碎机进行实体建模,应用有限元方法分析破碎机转子体的自由和约束模态,并且通过对破碎机破碎过程的仿真模拟得到工作状态下物料对转子体作用力变化曲线以及转子体的动态应力结果,以其为依据对转子体动态特性进行分析,分析结果为反击式破碎机转子体的设计和改进提供了依据。With the.finite-element, the article builds the dynamic model of the impact breaker and analyzes free and confined conditions of its rotor Further, it obtains the curve of broken material acting forces against the rotor and the dynamic stress conditions by simulation for the shattering process, and according to this analyzes the dynamic characteristics of the rotor. This is favorable to the rotor design and improvement of the impact crusher.
