Battery packs are one of the two main components relied on by Electric Vehicles (EV) for vital parameters such as speed, mileage, and torque. Hundreds or thousands of battery cells must be combined to provide the demanded voltage and current required to drive electric vehicles (EV).

EDM’s Account Management program controls the accessibility of features from different users. This provides a structure for managing the privileges for different groups of users. The Account Manager can be used to prevent lower-level users from adjusting parameters or display settings. It also allows users to customize the toolbars for a simplified user interface. By hiding certain features, the UI can be made much easier to use.

Is it really necessary to reject a double impact?
Are they really a problem?
Let's talk about this.
I know that many people will say that a double impact is totally unacceptable. It is not the optimum condition for collecting impact data for a modal test. However, under certain circumstances, it may be reasonable to accept a measurement that has resulted from a double impact. Let's discuss this problem that may arise when a double impact occurs and explain how to determine if the measurement is acceptable or not.

Read moreAutomatically Run Pre-Defined Vibration Tests Using Digital Inputs
Combined vibration testing is gaining prominence due to the advancement of test equipment technology driven by the need to accomplish simultaneous testing of multiple measurement quantities. Vibration testing combined with temperature, humidity or a combination of other quantities has enabled the creation of test environments closely resembling typical scenarios in which DUTs operate.

I ran one test with an x-excitation and can see some modes and another test with a y-excitation and see some different modes. Could I use an oblique angle instead?
Well, that's a very good question. Its one that comes up often in terms of running modal tests with a shaker excitation. Of course it is totally acceptable to run one test with a shaker at some oblique angle to the structure. But the only thing we need to be careful about is to assure that we don't select the reference point at the node of a mode.
