Polymer base for hybrid powertrain and NVH test installations
View Patent ↗A powertrain test installation is disclosed that includes a polymer base, which is supported on a concrete slab, for example. A dynamometer is mounted on the polymer base. A frame is mounted to the polymer base and is configured to support a powertrain component to be coupled to the dynamometer. The powertrain test system is installed, for example, by providing a floor, which is a concrete slab, for example. The floor is cut to provide a gap between a support floor and an adjacent floor that is arranged about the support floor. A polymer base is arranged on the support floor interiorly of the gap so that the polymer base is isolated from the adjacent floor. A dynamometer is secured to the polymer base. A frame is secured to the polymer base and is configured to support a powertrain test component, such as an electric motor.
