卫生洁具水包内流速的应变式测试
摘要
卫生洁具的排水过程具有“带自由面”、“非恒定”、“过程时间短”的特性
且水包内的水流为一薄层水流
其水流速度能反映水流对水包壁面的冲刷作用的大小。通过对卫生洁具的水包内水流速度测试
获得了一种可针对带自由面的薄层水流速的和基于应变传感技术的测试方法
包括其测试原理、速度传感器的设计、测试系统设计、数据采集及计算机处理方法
并给出了测试的结果以及标定方法。
Abstract
The properties of flushing process of ceramic sanitary ware are unsteady
rapidly and with free surface
and water flow in the water bowl is a thin film.The water flow velocity reflects the wash out capability of water flow to wall of water bowl.Through measuring the water flow velocity in the water bowl of ceramic sanitary ware
a method to measure the thin film water flow based on strain gauge is obtained.The measure principle
the velocity sensor design
the measure system
data collecting and data processing method are introduced.And the result of the measurement and the method of demarcate are also given.
