Shock Absorbers Impact Test
Shock absorbers used in an automotive suspension assembly can experience impact damage. In real life conditions, these dampers are exposed to multiple impacts and are expected to make vibrations as smooth as possible (e.g. speed bumps). It’s necessary for suppliers to understand the behavior of the rubber damper or plastic part connected to it after repeated impact cycles.
Instron designed a special tall thermostatic chamber for a 9450 Drop Tower to accommodate a 600 mm tall damper assembly and developed a dedicated software module to perform multiple impacts on it. This software module enables automatic repetitive impact tests up to 1200 consecutive cycles to simulate the actual use scenario. This helped our customer with new product development and material selection for dampers to be used in this application.
