Dynamic Performance of Concrete Mixing Truck's Rotating Drum

  • 摘要: 以混凝土搅拌车为研究对象,对搅拌车搅拌转筒进行了受力分析,得到了各支撑力的计算模型。归纳了搅拌转筒内混凝土液面形状的计算方法,分析了搅拌转筒转速、倾斜角度以及混凝土液位对筒内液面形状的影响。构建了考虑混凝土液面分布形状的新型传递矩阵模型,针对算例进行了分析,研究了搅拌转筒转速、倾斜角度、混凝土液位对搅拌转筒振动性能的影响。发现搅拌转筒的振型呈现非对称分布,随着转速的增大,搅拌转筒的振动幅度不断减小;随着倾斜角度的增大,搅拌转筒的最大振幅几乎不发生改变,但其振动峰值的位置逐渐向右移动;搅拌转筒的不平衡响应振幅随着混凝土液位高度的下降而增大,振动峰值逐渐向左移动。
