Powertrain supporting bracket and powertrain simulating test table

The invention provides a powerstrain supporting bracket and a powertrain simulating test table, wherein the powertrain supporting bracket comprises an auxiliary support beam, two parallel main support beams, and two parallel sliding grooves. The auxiliary support beam is arranged between and connected to the two main support beams. Each main support beam comprises a horizontal beam and a vertical beam. The auxiliary support beam is perpendicular to both the horizontal support beam and the vertical support beam. The sliding grooves are arranged under the main support beams and are parallel to the auxiliary support beam. The main support beams can slide along the sliding grooves. The powertrain supporting bracket and powertrain simulating test table are able to support a powertrain of varied specifications, and can also simulate the condition of a powertrain in the running state of an automobile.
