【摘要】 本文对相位法模量仪的测量原理进行了理论分析,指出在建立其数学模型时,必须考虑试件分布质量的影响,在实际测量阻尼材料动态特性时,必须综合考虑试件长度、实剪切模量、体密度以及振动频率诸因素,才能提高测量精度。本文还在自行设计与制造的扭转式相位法测量装置上进行了实验研究,实验结果与理论分析结论吻合较好,从而为我国自制相位法模量仪准备了理论的和实验的基础。更多还原

【Abstract】 The measuring prinoiple of visco-elasticimeter based on the phase method isanalysed theoretically. It is explained that the effect of distributive mass of test-piece measured must be considered when mathematics model is established. Whenthe dynamic properties of damping materials are measured the length of thetest-piece, the real shear modulo, the density of the volume, and the vibratingfrequency should be considered in order to raise the measuring precision. Anexperiment is made with the self-made measuring equipment working on thephase measuring prinoiple, where the test-piece vibrates torsionally. The resultsof the experiment are agree well with theoretical analysis.更多还原
