Abstract
An improved isolator includes a bar of elongated base-forming members adapted to be mounted to a supporting surface and an elongated load-supporting bar adapted to support the load connected to, and supported above, the base-forming bars by a pair of arched flexural supports. Each support is formed of a series of individual flexural elements. The flexural elements are oriented or biased at an acute angle with respect to the horizontal, the first group of elements being biased in an angle opposed to that of the second group. The invention demonstrates more symmetrical response over an equivalent conventional isolator and permits further tuning of isolator response in accordance with load requirements.
Claims10
An improved isolator apparatus comprising:
- first and second parallel base-forming bar means affixed to a base plate for securing the apparatus to a structure subject to vibration and shock;
- a load-supporting bar means parallel to said base-forming bar means for securing the apparatus to a structure sought to be isolated from vibration;
- and
- first and second flexural support means supporting said load-supporting bar in a force-damping relationship above said base-forming bars, each of said flexural support means comprising a group of opposed flexural support element pairs, each of said flexural support element pairs having a first element having a first end affixed to the first base-forming bar means and a second end affixed to said load-supporting bar and a second element having a first end affixed to said second base-forming bar and a second end affixed to said load-supporting bar, the flexural support element pairs of said first and second flexural support means being located and offset in planes at acute angles from the horizontal defined by said base means, the offset of the element pairs of said first group being equal and opposite to that of said element pairs of said second group.
