CAE Service

Structural Analysis

All structural design services companies start by simulating a geometric model of the product. This model needs to be meshable into a correct finite element mesh. This is done in order to ensure that the CAD geometry will mesh and will provide important data like stresses, displacements or temperature distribution with accepted accuracy. Structural analysis of a product is an iterative process. The structural analyst creates a discrete geometric model based on the designer's inputs and by using some CAE software tools. The designer then validates the products based on the simulation results.

After optimization, the product design is again sent to the structural analyst, and the cycle continues. While a few companies have in-house CAD / CAE designers, they are not in a position to purchase the latest CAE software required for the structural analysis. This is where they outsource the structural analysis process to companies that have this expertise.

Computer Aided Analysis

Computer Aided Analysis programs require good knowledge of the molding process and of the assumptions made in the computer analysis programs in order to obtain reasonably accurate results. Probably the most basic assumptions deal with the relationship between pressure, temperature, and volume.

These relationships are well known and documented for relatively slow cooling rates, say five degrees per minute. The relationships between these variables at cooling rates of perhaps hundreds of degrees per minute are not commonly available.

These three variables are the most prominent of the variables to be considered, but there are approximately thirty total variables. Most finite-element–based analysis programs use what are called midplane analysis techniques.

Car Crash Analysis

Car crash simulations are among the most critical simulations at the Vehicle Integration level in the development cycle. Meeting crash requirements as per different Vehicle Safety Standards (FMVSS, NCAP, EC, Japanese-NCAP) is a compliance aspect to deliver a safe car to end customers.

There are different types of crash simulations like full frontal, side, rear, rollover at the vehicle level, and Crash Management System (CMS), seating, interior crash at the system level.

Other applications include drop testing, forming simulation, and shock loads.
