    • PURPOSE:To enable positive transmission by a simple construction vibration of a vibrating bench to a test piece, by forming a vacuum chamber between the test piece and a jig proper and by suction-fastening the test piece to the jig proper. CONSTITUTION:A mounting jig 11 consists of a jig proper 14 and an elastic sealing member 15 formed with a rubber sheat, etc., and on the top surface of jig proper 14 is provided with dents 16..., and a through-hole 17 is bored in the sealing member 15 in an opposed manner. A vacuum chamber 18 is constituted by the dent 16 and a small hole 17a and it is connected to a pressure reducing apparatus, such as a vacuum pump, etc. through a pressure reducing passage 19. A test piece 13 is fixed in a mounting hole 17b of sealing member 15 and when pressure is reduced by a reducing unit, then the test piece 13 is suction-fixed onto the jig proper 14. In case when a mass of test piece 13 is relatively small, vibration is transmitted positively to the test piece 13 without absorption of vibration of the vibration bench 6 by the sealing member 15.
    • 目的:通过将振动台的简单结构振动传递给试件,通过在试件和夹具之间形成真空室,并通过将试件吸附固定在夹具上来实现正传动。 构成:安装夹具11由夹具本体14和形成有橡胶护套等的弹性密封构件15组成,并且在夹具本体14的顶面设置有凹部16 ...,通孔 17以相反的方式在密封构件15中钻孔。 真空室18由凹部16和小孔17a构成,并且通过减压通路19与真空泵等减压装置连接。试验片13固定在安装孔 17b,并且当通过还原单元减压时,将试验片13抽吸固定在夹具14上。在试件13的质量相对较小的情况下,振动被积极地传递到试验 而没有通过密封构件15吸收振动台6的振动。
