What You Will Create and Simulate
In this tutorial, you validate an Adams kinematic model of an automotive quarter suspension against a physical model, to verify if the Adams model response to imported physical test data matches the physical model response to the same data.
You will use Adams Durability to perform a load cycle on an Adams suspension model using physical test data in RPC III format. You will write out response time histories in DAC format and compare this response to output data from a test lab.
You will use an existing Adams model of a quarter vehicle suspension, which we developed using CAD data, and go through the steps shown next:
■First, you will define two joint motions that reference spline data and vary over time and cause displacement at the spindle.
■Next, you will instrument the model to monitor the resulting displacement.
■After that, you will simulate the model and output the data in DAC format.
■Finally, you will compare the virtual test data (in DAC format) with physical test data (in RPC III format), from a physical model. The physical test data represents 10 seconds of motion data sampled at a rate of 51.2 points per second in a test lab.
