金属ダイヤフラムの線形中心たわみの理論的一考察

抄録

The corrugated metallic diaphragm capsule is used as low pressure sensing elements in precision pressure gauges, pressure transducers, pressure switches, and various aircraft instruments.
The author's analysis is made to apply the pure bending theory of anisotropic circular plate to a linear deflection type diaphragm. For the linear deflection diaphragm with uniform load applied and for that with concentrated load applied at the center, respective useful equations in design are obtained. And various factors in equations are also obtained from the geometrical dimensions and physical properties.
According to these analysis, it is found that the linear max. deflection of the diaphragm can be calculated easily, from such values as Young's modulus, thickness, diaphragm diameter, and geometrical dimensions of corrugated waves.
As a result of these various experiments made on the actual diaphragms, it is found that the experimental data satisfactorily coincided with the author's theoretical calculations.
