本发明公开了一种用于降低制品对机械振动的敏感性的设备，该设备包括：框架；(300)安装在框架中、用于沿着位移的第一轴、相对于框架双方向移动的第一(m1)和第二平面质量块；可围绕固定于框架的第一支点(360)旋转的第一杠杆(330)，该杠杆的一端与第一质量块(m1)连接而另一端与第二质量块(m2)连接，并且该支点(360)设置在杠杆的端点之间，其中响应沿着位移轴施加于框架上的机械振动，通过第一质量块围绕支点作用的转矩由通过第二质量块围绕支点作用的转矩抵消，使得所用由第一质量块承载的制品具有对于振动的、降低的敏感性。 Apparatus for reducing sensitivity of an article to mechanical shock comprises a frame; first and second planar masses mounted in the frame for bi-directional movement relative to the frame along a first axis of displacement; a first lever pivotable about a first fulcrum secured to the frame; the lever having one end connected to the first mass and the other end connected to the second mass, and the fulcrum being disposed between the ends of the lever; whereby the torque exerted about the fulcrum by the first mass is countered by the torque exerted about the fulcrum by the second mass in response to a mechanical shock applied to the frame along the axis of displacement such that an article carried by the first mass in use has reduced sensitivity to the shock.
