Car accident simulation software

EDVDS was used to simulate the braking and steering dynamics of the tractor-trailer in a downhill curve. The vehicles' tires and bodies interact directly with the resulting surface mesh.

With no additional work, the cause of the crash was obvious by replaying the simulation with HVE's virtual camera attached to the witnesses and driver of each vehicle. HVE's 3-D viewers allow you to zoom, dolly, pan and even spin the entire world.

The GATB human simulation to the right involved four occupants in a passenger car. Not only did the occupants strike the vehicle interior, they also struck each other. Or simply forgot to maintain your vehicle properly?

Do you find yourself describing how the car accident happened to your friends and family members when they ask you about it? It can be tough to explain how the accident occurred verbally, but a car accident diagram shows it all. It may not be that important to show the car accident diagram to your friends and family members but it may be useful if you need to talk to the insurance company when making a claim.

One such online web-based car crash simulation software which is free and available online for you to use is AccidentSketch. The image on the left is another sample of an accident sketch. There are many ways how this road diagramming online tool can be utilized. Driving schools can also use this online tool to sketch some car driving instructions for their students to look through before they actually get on the car.

A lot happens during a real crash test and it happens fast. To capture crash data, engineers place sensors throughout the test car. Comparing results from crash simulations with real crash tests improves the accuracy of both. Software engineers fine-tune their models based on real-world results. Decades before other automakers, Stutz designed cars with safety in mind. They made cars with safety glass, a low center of gravity, four-wheel brakes, high visibility, and fire-resistant upholstery.

Automakers today offer many more vehicle models than they used to. Simulation and design software allow new designs to be created more quickly than the paper designs of yesteryear. Software then calculates how the forces in a crash would affect each of those points to determine the overall result of the impact.

Computer-aided design CAD lets car designers balance all these factors, simulating the performance and tweaking the look of each new model before building actual prototypes. Auto manufacturers adopted many CAD techniques from aeronautical engineers, who pioneered the use of powerful computers to model the performance of aircraft designs. The system acted as an electronic sketchpad and controlled a milling machine to produce a physical model.

One of the earliest practical uses of the finite element method FEM was in the design of aircraft wings. Here, the color-coded regions show varying levels of mechanical stress on the wing.

Software simulations play a part beyond crash tests. They touch every step, from design and engineering through production. For example, fluid dynamics computations analyze aerodynamics to improve fuel efficiency.

Performance tests provide feedback as the design evolves. And simulating the manufacturing process identifies ways to increase efficiency or reduce waste. To improve fuel economy, car manufacturers try to reduce wind resistance.

Computational fluid dynamics CFD simulations show how air moves around a moving object, like this minivan, allowing designers to adjust its shape. The average modern car has about 25, parts, each with their own CAD drawing. From the tail light to the front grille, the complete car exists in software as a series of CAD files. There are many steps in designing, testing, and building a safe, stylish car.

Software plays a central role in each. Design Computer-aided Design CAD software transforms ideas into images, showing how the car will look, and creating a data set representing the car.

Simulated Crash Finally, engineers crash the car into a barrier—virtually—using powerful software to simulate the effect on each element.
