- The primary function of a powertrain mounting bracket is to support the powertrain system in all road conditions. Since it is impossible to change the supporting locations and types of support at a later stage of the development after the powertrain is packaged, the mounting brackets must be verified for all kinds of requirements like NVH, crash, durability and impact strength at the early design stage. Generally, all car manufacturers ensure powertrain mount bracket design through CAE against road load data (RLD), corresponding damage for cumulative strain or stress against specified service life requirements. However, it is challenging to simulate the impact load through CAE, which requires highly complex input data. The energy absorption characteristics of the powertrain mounting bracket are mainly influenced by two variables, the material and the design. Though a bracket may be sound in design for durability, there is a chance of failure due to impact loading. This paper outlines the study of impact loading on powertrain mount brackets and the effect of different mass and height tests on failure location. A case study is discussed in detail about the approach, and an experiment is carried out on the Izod Impact tester for a robust powertrain mount bracket design.
