摘要

为了确保在一定的振动幅度和精度的条件下提高气动悬浮的承载力

提出了一种采用超声悬浮-气浮混合式悬浮方式来提高气动悬浮承载力的新方法。通过ANSYS软件对超声悬浮核心部件(压电换能器)进行优化设计加工

制作了混合式悬浮装置实验样机

并进行了悬浮能力的测试

得到的实验测试结果与理论计算结果相一致。优化后的圆盘压电换能器可悬浮起质量为3 kg的物体

单位面积的悬浮质量可达59.7 g/cm

。实验结果表明

该混合式悬浮装置的悬浮承载力大于超声悬浮与气动悬浮的承载力之和

当供气压力为0.2 MPa时

混合式悬浮承载力约等于2倍的超声悬浮承载力与气动悬浮承载力之和。因此

该混合式悬浮装置可大幅度地提高气浮支承的悬浮能力

并且不改变气浮支承的振动幅度和精度。

Abstract

To improve the bearing capacity of pneumatic suspension with certain vibration amplitude and precision

a new way to synthesize ultrasonic levitation and pneumatic suspension is put forward. The corn component piezoelectric transducer of the ultrasonic levitation is optimized with ANSYS. Then the hybrid suspension prototype is manufactured following the optimized design and the experiments of suspending power are conducted

and the results well coincide with the theoretical calculations. The optimized one enables to suspend body of 3 kg

and the suspension weight per unit area of gets to 59.7 g/cm

. The bearing capacity of hybrid suspension is larger than the sum of the bearing capacity of ultrasonic levitation and pneumatic suspension and the capacity is approximately equal to th

e sum of the pneumatic suspension and twice ultrasonic levitation with constant vibration amplitude and precision

when the supply pressure is 0.2 MPa.
