【Abstract】 A dynamic displacement measuring system is used for such experiment when a softbody runs into an objective, and a bird runs into an aircraft. A high frequency non contact measurement method is presented, in which hall elements are employed to pick up the dynamic displacement and novel circuit is used as nonlinear compensation one. The system is used for experiments of bird colliding into the aircraft. Experiments show that the system is effective.更多还原
