【Abstract】 A brief analysis was made of the characteristics and applicability of a few commonly used materials for measuring Young’s modulus.Based on the Young’s modulus experimental device using measurement materials of dynamic method,the shortcomings of the hanging test stand for measuring the Young’s modulus of single mode fiber were investigated,the design conception scheme in which the suspension type was replaced with a support type scale accompanied with a measuring table was put forward,on the basis of which,a new design scheme for measuring fiber modulus via dynamic method was proposed,and the corresponding calculation formula was presented.更多还原
