Description
技术领域 technical field
本发明涉及机械领域，特别是涉及一种低频力学谱仪上测量内耗用的多向可调支撑装置。 The invention relates to the mechanical field, in particular to a multidirectional adjustable support device for measuring internal friction on a low-frequency mechanical spectrometer.
背景技术 Background technique
低频内耗的测量是在低频力学谱仪上完成的，是对竖立的一端固定（下端）、一端自由的长条试样从自由端（上端）加一个循环的很小的应力（水平方向应力），然后测量试样的振幅衰减（自由衰减法）或应变滞后于应力的相角（强迫振动法）来度量内耗值的，这就要求固定端（下端）和自由端（上端）中心线一致且垂直于水平方向以保证测量的精确度。由于零件制造误差的存在，固定端（下端）和自由端（上端）中心线一致性要通过设置机构来实现，而下端是固定端，不能调整，只有靠调整上端的支撑点，而上端是用棉线支撑在支撑机构上并用配重平衡，因此，需要设计的支撑机构能对棉线的支撑点的空间位置进行调整。首先调整支撑棉线的两个支点的连线与横梁长度方向平行，然后调整连线与固定端（下端）和自由端（上端）中心线（也是试样的中心线）相交（对中）。另外，为了测量不同长度的样品，有时需要将棉线的支撑点升高或降低，因此，支撑机构的高度在竖直方向也需要可调。 The measurement of low-frequency internal friction is done on a low-frequency mechanical spectrometer, which is to add a small stress (horizontal direction stress) of a cycle from the free end (upper end) to the vertical strip with one end fixed (lower end) and one end free. , and then measure the amplitude attenuation of the sample (free decay method) or the phase angle of the strain lagging behind the stress (forced vibration method) to measure the internal friction value, which requires that the centerlines of the fixed end (lower end) and the free end (upper end) are consistent and Vertical to the horizontal direction to ensure the accuracy of the measurement. Due to the existence of part manufacturing errors, the consistency of the centerlines of the fixed end (lower end) and the free end (upper end) must be achieved by setting the mechanism, while the lower end is the fixed end and cannot be adjusted. Only by adjusting the support point of the upper end, while the upper end is used The cotton thread is supported on the supporting mechanism and balanced with a counterweight. Therefore, the supporting mechanism that needs to be designed can adjust the spatial position of the supporting point of the cotton thread. First adjust the connection line of the two fulcrums supporting the cotton thread to be parallel to the length direction of the beam, and then adjust the connection line to intersect (center) the centerlines of the fixed end (lower end) and the free end (upper end) (also the centerline of the sample). In addition, in order to measure samples of different lengths, it is sometimes necessary to raise or lower the supporting point of the cotton thread, therefore, the height of the supporting mechanism also needs to be adjustable in the vertical direction.
