Co-Simulating Multibody Systems: Controlling Bushing Force Parameters with MATLAB and MSC Adams

Introduction

In the realm of engineering simulations, the capability to combine various software tools can drastically enhance the accuracy and efficiency of system analyses. One common challenge arises when working with the co-simulation of Multibody Systems in MSC Adams and MATLAB. Engineers often seek to manipulate parameters—such as bushing forces—dynamically within MATLAB, particularly when the variables required for these adjustments are tied to state variables.

In this post, we’ll explore how to allow MATLAB to control the parameters of the bushing force in Adams during co-simulation, facilitating dynamic adjustments based on the results obtained.

The Challenge

When dealing with complex multibody systems, a common requirement is to adjust certain parameters in real-time to identify system characteristics. In this case, we focus on:

Bushing Force: A parameter crucial for simulating the flexibility and response of connections within a multibody system.

State Variables: These are necessary for MATLAB to communicate effectively with Adams, yet direct control over bushing parameters is not readily available.

The Solution

The key to overcoming this issue lies in utilizing the ADAMS_init array which allows us to modify design values that are integrated into the bushing force. Below is a structured explanation of the steps involved in achieving this.

Step 1: Setting Up Your Environment

Before you begin, ensure you have the following:

MSC Adams: Installed and configured for your multibody simulations.

MATLAB/Simulink: Ready for the control algorithms and scripting.

Step 2: Understanding the ADAMS_init Array

The ADAMS_init array serves as a powerful tool within Adams that enables you to change various design values at runtime.

By manipulating this array, you can set values that MATLAB will use to control the bushing forces in your simulation.

Step 3: Writing the MATLAB Script

Here’s a simple outline of a MATLAB script designed to modify the bushing force parameters:

Step 4: Testing and Validation

After scripting, it’s critical to validate your setup:

Run simulations and monitor how your changes impact system behavior.

Use tools in Adams and MATLAB for visualization to ensure accurate performance is achieved.

Conclusion

By leveraging the ADAMS_init array and crafting a simple MATLAB script, it is indeed possible to let MATLAB control parameters such as bushing force in MSC Adams during co-simulation. This flexibility not only enhances the accuracy of your models but also speeds up the identification of critical parameters in dynamic systems.
