A New Method for Generating Sine-on-Random Tests Using Real-World Data
Leo Zhang Country manager - China Vibration Research China - PRC USA
In the real world, engine-mounted components are exposed to a unique vibration environment. A Sine-on-Random test should be created to effectively reproduce this environment on a shaker; however, generating a repeatable accelerated test reflective of these engine environments can be difficult and time-consuming. In this presentation, we evaluate different test generation techniques and compare failure modes generated by shaker tests. Additionally, we validate a new method of analysis, acceleration, and generation. The result is a Sine-on-Random test designed using field data to replicate an engine environment on an electrodynamic shaker.

Introduction to NVH in Electric Motors and case study
Li Yong EPT sales development manager HBM China
Electrification has changed how we experience a vehicle’s noise and how the vibration effects the durability of parts. Electric motors are fundamentally quieter and have higher rotational speeds than their engine counterparts, which has created a need to look at these engineering problems differently.
Many industries, including automotive and aerospace, have started merging their NVH and powertrain departments to include the user’s experience into their designs. Testing for noise and vibration and electrical quantities at the same time will provide an extended insight into how the electric machines and inverters are causing noise and vibration and how to amplify or mitigate it.
This topic will discuss the following:
What causes noise and vibration in electric machines
How electrical and mechanical signals are correlated
How simultaneous testing of electrical and NVH signals can speed up testing
Mapping NVH against motor controls
