摘    要：分析了混凝土砌块振动密实成型效果的影响因素，采用端面式混沌激振器，建立了混沌振动成型机的动力学模型，并进行了动力学分析，得出混沌振动成型机具有较宽的振动频率、较高的振动加速度、振幅和振动烈度，能增加被振混凝土混合物中各种物料与物料之间碰撞和拌合的机会，并降低模具与物料之间的摩擦，提高密实性和均匀性，同时，具有对所加工的砌块原材料适应面宽等优势，最后通过实例分析验证了其有效性。

Abstract：The influence factors of concrete block forming vibration close-grained effect is analyzed.  The chaotic vibrator is applied, the dynamics model of chaotic vibration molding  is established  and motion is analyzed, The results show that the vibration of the chaotic vibration molding machine has a wide frequency, high vibration acceleration and amplitude and vibration intensity, the vibration concrete mixture chance of collision and mixing between all kinds of material can be increased and the friction between mold and material can be reduced and has the better compactness, uniformity, high efficiency and adaptation of wide for block processing by the raw materials. At last, its effectiveness is prored by the example analysis.
