Crash and Occupant Safety Simulations

Crash and safety is very crucial to product development in the automotive industry. It provides deep insight into structural behaviors and the impact on occupants. In addition to understanding the behaviors, a robust FE model can assist with providing quick design studies that would otherwise be time and cost consuming. Worksbot has worked with several of the leading OEMs and suppliers to offer dynamic solutions for crash and safety (interior and exterior). Apart from full vehicle, such analysis is an integral component to subsystem developments; bumpers, closures, restraint system and airbags.
While managing countless projects with OEMs and suppliers from all over the world, Worksbot has gained a firm understanding of all aspects of crash and safety. Alongside, a logical comprehension of how load-path along with material and gauge works in diverse scenarios, such as:

  • Restraint System (Airbags, Seat Belt, etc.).
  • Material modeling for metals, composites appropriate for crash loading.
  • Developing best practices that manifest realistic results.
  • Proven track record of CAE vs test correlation.

Noise, Vibration, and Harshness (NVH)

Natural frequency or frequency response is a key attribute to the robustness of any structure. Worksbot is well versed in analyzing all of the following major attributes for the robustness of a design. And not only do they help identify issues, but they also provide the most efficient alternatives to improve performance. This includes:
  • Model Analysis
  • Static and Dynamic Stiffness
  • Frequency Response Analysis
  • Point Mobility
  • Attachment Stiffness Analysis

Durability Simulation

Designing fail-safe components is the ultimate challenge for engineers. Fatigue damage can be catastrophic in terms of system performance and can lead to recalls. Many companies have been reducing the product development cycle to create products at a faster rate. Given that scenario, an efficient and accurate durability simulation becomes critical. Worksbot’s engineering team has the proven expertise and experience in designing components from a durability standpoint. Based on the client’s requirements and the given case, one of the two alternative approaches below can be adapted.
Static Load Representation
Standard industry practices, specifically for full vehicles, includes representing the road profile input (pothole, bump, curb, and cornering) in terms of static loads. The fatigue life is then calculated based on the test schedule using commercial solvers such as Ncode and FE Fatigue. Shaker table test simulations are also another way of analyzing durability behavior and commercial codes such as Abaqus and Nastran, both are used to perform such analysis.
VPGSuite Durability System Simulation
Alternatively, Worksbot has its own patented VPG Process to perform durability and other such proving ground simulations. The advantage here is the same crash model can be used for doing the durability analysis.
Worksbot will use the vehicle system or sub-system and all the data for chassis/suspension using VPGSuite to perform durability, ride, and handling system evaluation of the vehicle to identify any potential issues within the vehicle design before prototyping. VPGSuite uses LS-DYNA for real-time non-linear material and geometry to simulate the vehicle’s durability and fatigue life.

Vehicle Dynamics, Ride, and Handling

The suspension and steering behavior of a vehicle has the most perceptive effect on the driver, Hence determining the ride and handling behavior is extremely important. Worksbot has ample experience with such simulations also known as proving ground simulations. Backed up by the accuracy of LS Dyna and Worksbot's patented tire model, the engineering team can provide multiple levels of studies for ride and handling. Which can begin with pure rigid body kinematics to a fully deformable suspension and body model to account for compliance. The analysis also serves as precursors to chassis design in the absence of existing road load data. Also, for the predictions of forces on attachment and mounting points, such as; body mounts, engine mounts, battery, and fuel tank mounts. The results have been correlated with tests and proven by our OE partners. Subsequently, these analyses can also be used to predict the durability behavior of the components. Additional information on this can also be found on the VPGSuite Product Page. Worksbot is also well versed in analyzing durability and fatigue using commercial codes such as Ncode and how to efficiently remove or solve durability issues.

Weight/Cost Reduction Optimization

The ACP Process can be applied to a new design, to create a product concept or to assist with an existing product refinement. In this case, engineers start with a current product design that they intend to update, typically improving the design’s performance, reducing mass and cost. All while maintaining the existing packaging, manufacturing, and styling. In addition, 3G Optimization is used to synchronize material selection, material thickness, and shape parameterization so the correct material is placed at the right location within the structure for cost and mass reduction design objectives.

ACP Process

The Accelerated Concept to Product (ACP) Process® is a patented, performance-driven, and holistic virtual product development method. ACP is based on topology and parametric optimization under multi-disciplinary loading conditions. The process yields a design that is cost and weight efficient while meeting all of the performance attributes and manufacturing constraints. This process has revolutionized and streamlined the product development process, through optimization led design. The performance-driven development process relies heavily on optimization techniques to meet timing and budget targets, whereas traditional processes have been built around a build-test philosophy.

ACP is built on three basic pillars of design and development:

  • ACP Concept: Load path based on topology for multiple loading conditions (linear and non-linear).
  • ACP LF3G: Optimum geometry, grade and gage for the lowest weight and highest performance.
  • ACP HF3G: Design adaption based on manufacturing.
The basis of the ACP Process is to start from a clean sheet, developing a concept design based on multi-disciplinary topology optimizations. Contrary to conventional methods where just one or a few design concepts are evaluated, the ACP process allows for hundreds of design concepts under multiple load conditions. Only the concepts that meet all of the design targets and manufacturing constraints are initiated. The resulting concept(s) are designed, analyzed and optimized using loading, manufacturing, material, and cost constraints. CAD data is then generated for the optimal design. Next, Worksbot's engineering team takes the design to the production level (preparing it for manufacturing) based on the available manufacturing processes and provides production support.
The team offers continued assistance, executing an end to end product development project. They have completed projects for a variety of industries, demonstrating the versatility of the ACP Process. Worksbot offers training for the ACP process to guide customers through the individual functions and technology transfer.

Design Optimization

Topology and Load Path Optimization

Topology optimization has been around for many decades. Topology optimization can help engineers develop a design from a clean slate for different kinds of loads. It helps the user understand the load path based on a particular loadcase or a combination of different loadcases. Worksbot has expertise in asssting customers to better understand loadpath. Traditionally done for static loads, but now with new software such as LS TaSc, topology optimization can be done for dynamic loads as well. Worksbot has executed multiple projects to help customers produce new and efficient designs for multidisciplinary loads, leading to lower weight and costs. More information can be found on the ACP Process webpage {hyperlink}.

Parametric 3G Optimization

Weight and cost savings have always been alluring the manufacturers. Finding the right balance for optimum design which meets all the performance criterion is an art. Worksbot has developed their own processes while executing many diverse projects. The problem can be as simple as performing a gauge optimization or can be a full blown optimization involving Geometry, Grade and Gage.
Their team are experts in using tools to parameterize the geometry (morphing), making adjustments to the parametric optimization. Material Selection is a critical step in product development. Making the right selection of materials in the right location can provide mass savings and fulfill the desired performance/behavior in certain loading conditions – such as crash. Worksbot is highly experienced in performing weld optimization which can bring companies substantial cost savings.

Innovation R&D

Apart from conventional structural analysis used in the transportation industry, there are plenty of applications and domains where effective use of CAE can lead to innovative solutions for a variety of problems. Worksbot's engineering team think laterally about applying new solutions to many different problems and applications. Some of the applications include:
  • The redesign of the plastic solo cup for weight savings.
  • New barrel design and development for less mass.
  • Brake caliper optimization for less mass and cost savings.
  • New design and development of interior floor mats used in trucks and heavy machinery.
