Simulation and Analysis

What is Dynamic Analysis?

Dynamic stress can be obtained from the experiment (a sensor or assembly sensor on a physical component) or from the simulation. Using simulation, a representative load history must be created for accurate dynamic strain calculation, including inertia forces and external forces (for example, common reaction forces and torques). Multiple body dynamic analysis methods (discussed in Section 3), typically used for dynamic motion analysis, can be used for dynamic load analysis of mechanical systems. All bodies of the dynamic model are generally assumed to be rigid. The rigid body assumption for the suspension components of a vehicle usually gives reasonably accurate analysis results to support structural design for durability.

What is Finite Element Analysis?

Finite elements analysis (FEA) is a method of analysis that measures and concludes how a product or a system reacts to physical conditions such as strength, impact, vibration, shock wave, heat resistance, fluid flow in current living conditions. Finite element analysis indicates whether the product is working as it is broken, worn, or designed. This method is one of the key processes in the product development process.
FEA works by dividing a real object into numerous (hundreds of thousands) finite elements (mesh), such as small cubes and prisms. This method examines the state of each mesh structure through mathematical equations under physical conditions. An upper mathematical equation examines all these mesh structures in a holistic way. Finite elements analysis helps to estimate the behavior of products affected by many physical effects, including:

  1. Mechanical stress
  2. Mechanical vibration
  3. Fatigue
  4. Move
  5. Heat transfer
  6. Liquid flow
  7. Electrostatic
  8. Plastic injection molding
  1. It is basically a digital test method. Virtually examined in a computer environment before producing parts physically
  2. Because possible problems are displayed in a computer environment, regulations are revised in design and important steps are taken towards making smooth design.
  3. Structural behavior and good visualization of the fault are made under various loading conditions.
  4. Insight information (Weight, Power, Cost) for critical design parameters is obtained.
  5. Faster and cheaper design cycle.
  6. Weight reduction, topology optimization, metal substitution material changes can be done with faster, more effective and economical methods with finite elements method
