SiolidWorks Simulation Courses

SolidWorks Simulation Premium: Nonlinear & Dynamics

(1) Dynamics Analysis - 2 Days

Prerequisites: Must have attended the basic SolidWorks Simulation class, or must have an experience with SolidWorks + working basic knowledge of finite elements and of basic mechanical principles. The knowledge of basic principles in Vibrations is strongly recommended, but not required.

Description: TThis course is targeted for the users who would like to become productive in analyzing structures subjected to various types of dynamic loading. The material covered includes the time dependent analysis(force loads as well as motion shock loading examples), harmonic analysis and random vibration analysis (MILS-STD-810F example is included), response spectrum analysis, and introduction to nonlinear dynamics simulation.

The topics covered in this course are:
