一种小动静比橡胶隔振器仿真与试验
Numerical and Experimental Study of a Rubber Isolator with Low Dynamic to Static Stiffness Ratio
摘要
Abstract
Through the internal structure design of the rubber shock isolator,its dynamic stiffness is reduced with its bearing capacity ensured.The static deformation of the rubber isolator and its dynamic behavior under the given static defor-mation are simulated and analyzed.It shows that the isolator has a negative slope characteristic according to its static force vs.displacement curve,corresponding to the instability deformation of the internal structure of the isolator.The static pres-sure test,dynamic test and vibration transmission test for the vibration isolation system of the shock isolator are carried out.It is shown that the results of static force vs.displacement curve test show a negative slope characteristic,and at the natural frequencies at different working points on the static curve the negative slopes are minimum.关键词
