应变倍增器
摘要：
本发明公开了一种应变倍增器，该应变倍增器包括弓形结构(1)、弹性体(4)、两个支臂(2)和两个安装脚(3)，所述弓形结构(1)包括两个侧部(11)和将该两个侧部(11)的一端相连接的连接部(12)，所述两个支臂(2)的一端分别设置在所述弓形结构(1)的两个侧部(11)上，所述两个安装脚(3)分别设置在所述两个支臂(2)的下方，所述弹性体(4)设置在所述两个侧部(11)之间以使得所述弓形结构(1)处于预压力状态，其中，所述支臂(2)的拉伸刚度与所述弓形结构(1)的抗弯刚度的比值为35-45。通过上述技术方案，能够既保证应变倍增器的放大倍数，又能够使弓形结构的开口处的橡胶弹性体处于良好的受压状态。
摘要（英）：

The invention discloses a strain multiplier which comprises an arc structure (1), an elastic body (4), two support arms (2) and two mounting feet (3); the arc structure (1) comprises two side parts (11) and a connecting part (12) which connects one ends of the two side parts (11); one ends of the two support arms (2) are respectively arranged on two side parts (11) of the arc structure (1); the two mounting feet (3) are respectively arranged below the two support arms (2); and the elastic body (4) is arranged between the two side parts (11) so that the arc structure (1) is in a prestress state, wherein the ratio of the stretching rigidity of the support arms (2) to the flexural rigidity of the arc structure (1) is 35-45. Through the technical scheme, not only can the amplification factor of the strain multiplier be ensured, but also the rubber elastic body at the opening part of the arc structure can be in a favorable pressed state.
