| Abstract: | The experimental method of measuring the strain mobility of glass fibre reinforced ployseter bending tubes was discussed,the calibration curves of the force canal and the strain canal were given, the model frequencies and the model damp ratios of the first step and the second step of the glass fibre reinforced polyester bending tubes and the dynamic strain value per newton force were determined,the dynamic stress of the bending tubes was analysed with the amplitude frequency characteristics and phase frequency characteristics of the strain mobility,the correctness of dynamic measurement was verified with static experiments. |
