SHAKER FOR MEASURING YOUNG'S MODULUS IN WOOD SUCH AS VENEER, VIBRATION RECEPTION MACHINE, AND MEASURING INSTRUMENT FOR YOUNG'S MODULUS

摘要

PROBLEM TO BE SOLVED: To provide a vibration machine for measuring Young's modulus in wood such as veneer that reliably gives perpendicular vibration to the wood such as veneer from a first mobile unit, at the same time detects that the first mobile unit has given perpendicular vibration by a first acceleration detector, and accurately obtains the propagation speed of the perpendicular vibration in the wood such as veneer for accurately measuring the Young's modulus, to provide a vibration reception machine for measuring the Young's modulus of wood such as veneer that freely moves in a direction away from the wood even if a second mobile unit is in contact with the wood such as veneer, appropriately vibrates and receives perpendicular vibration from the wood such as veneer, and to provide a measuring instrument of Young's modulus in the wood such as veneer that can efficiently and accurately measure the Young's modulus in the wood such as veneer in a transport state.;SOLUTION: The first mobile unit is reciprocated toward the wood such as veneer in contact with the wood such as veneer. The acceleration of the first mobile unit is detected by reciprocation by the first acceleration detection that is provided at the first mobile unit. Force toward the wood such as veneer is applied to the first mobile unit by an actuation member, thus generating perpendicular vibration when measuring the Young's modulus in the wood such as veneer.;COPYRIGHT: (C)2003,JPO
