Vertical Extension Platform︱The extension platform is usually used as a platform for larger mounting specimens, which can be square or round or user-defined. In order to reduce the influence of dynamic characteristics of the expansion platforms, all the expansion platforms must be modeled and analyzed for their modal frequencies. These expansion platforms are generally made of magnesium alloy casting and attached with damping materials.
