In almost all industries, multi-axis shaker tables are often used to study damage caused by motion including inertia loads or external forces in time domain or frequency domain. This process is highly expensive and time consuming requiring expensive protypes and fixture buildings. Learn how: The use of simulation can speed up the process and reduce cost significantly. Structural …
