摘要

为推广Covid-19社交距离协议，为个人或有限数量的用户开发了空间尺寸为230×210×210 mm3的微型静水压力仪(MHSPA)。用石膏材料(CaSO2.0.5H2 O)制成的带有倾斜圆形段的实心半球，并涂上填充腻子和油漆，以代替常规象限。将固体固定在枢轴上的水平梁上，在不同高度的水中测量由液体引起的流体静力。结果表明，该装置可用于模拟不同液体高度下圆形表面静水压力的变化，与平均理论值的平均差值为4.38%。与文献中使用传统象限的其他结果相比，相关误差很小，并且表明在学校实验室中采用该设备进行静压演示的可能性。

Design modification and performance evaluation of mini-hydrostatic pressure apparatus for inclined plane circular surface

Mini-Hydrostatic Pressure Apparatus (MHSPA), of spatial size 230×210×210 mm3, was developed for individual or limited number of users to promote Covid-19 social distance protocol. A solid hemisphere with an inclined circular segment made from gypsum material (CaSO2.0.5H2 O) and coated with filler putty and oil paint, is used in place of the regular quadrants. With the solid attached to a horizontal beam mounted over a pivot, hydrostatic forces due to liquids were measured at different heights of water. The results showed that the assembly could be used to demonstrate variation of hydrostatic pressure on circular surfaces at different heights of liquid with an average difference of 4.38% against average theoretical values. Compared to other results from the use of conventional quadrants in literature, the associated error is minimal, and indicates the possibility of adopting the apparatus in school laboratories for static pressure demonstration.

期刊介绍： Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
