超声振动对皮质骨钻削温度的影响研究
|
摘要
为研究超声振动参数(振幅、频率)变化对钻削皮质骨切削温度的影响,运用有限元软件建立超声振动钻削的三维仿真模型,通过使用新鲜的猪股骨进行试验比较超声振动钻削与常规钻削皮质骨骨孔温度变化规律并对模型进行验证。结果表明:振动钻削能显著降低皮质骨钻孔的切削温度;该模型在一定程度上是可信的;研究范围内切削温度随振动频率、振幅增大而减小。
In order to study the relationship between the ultrasonic vibration parameters( amplitude,frequency) and the cutting temperature of the cortical bone,a three-dimensional simulation model of ultrasonic vibration drilling was established by finite element software. An experiment comparison of cortical bone temperature for ultrasonic vibration drilling and conventional drilling using fresh porcine femur was made to validate the model. The result shows that vibrational drilling can significantly reduce the cutting temperature in drilling of cortical bone; the model is credible to some extent; the cutting temperature tends to decrease with the increase of vibrational frequency and amplitude within research range.
