Conventionally,to produce a linear motion,one motor’s stator is employed to drive one runner moving forward or *** far,there is almost no report of one electromechanical motor or piezoelectric ultrasonic motor that can directly generate two symmetrical linear motions,while this function is desired for precise scissoring and grasping in the minimally invasive surgery ***,we report a brandnew symmetric-actuating linear piezoceramic ultrasonic motor capable of generating symmetrical linear motions of two outputs directly without additional mechanical transmission *** key component of the motor is an(2×3)arrayed piezoceramic bar stator operating in the coupled resonant mode of the first longitudinal(L_(1))and third bending(B_(3))modes,leading to symmetric elliptical vibration trajectories at its two ends.A pair of microsurgical scissors is used as the end-effector,demonstrating a very promising future for high-precision microsurgical operations.

为解决水泥搅拌桩成桩质量缺陷,提升实体工程品质,通过分析水泥搅拌桩成桩质量的影响因子,研究造成水泥搅拌桩成桩质量缺陷的原因,针对每种原因提出相应的解决措施,分析钻杆下沉或提升速度、转速、翼片宽度、翼片角度、翼片枚数、翼片组合方式等参数对成桩效果的影响,并通过建立数学模型进行剖析。得出:当翼片枚数、翼片有效搅拌宽度一定时,钻杆转速越大,所允许钻杆下沉和提升速度越大;搅拌桩成桩质量不受翼片间距的影响。
