Detailed design is often considered the most crucial stage in the design process. After general sizing and structural validation has been completed, localized regions need to be examined and optimized.
ATA has extensive design experience in this realm of product development. Our background in fatigue assessment, 3rd party design review, and structural analysis gives us unique insight into the issues that need to be examined during detailed design.
From verifying that the product is designed for the appropriate life cycles to minimizing manufacturing costs, we can guide your product to success.
Joint Design and Analysis
Joint failure in structures is the most common type of failure. ATA staff are experts in joint analysis during the detailed design process. Some important types of connections that ATA has extensive experience with include:
- Welded – making a structural welded connection is a common fabrication technique. However, the joint strength can vary depending on loading environments, parent material, extent of the heat affected zone, weld detail classification, and a number of other factors. It is important to make sure that your structure is verified for all possibilities.
- Bolted – joints of this classification fall under either slip critical or bearing style connections. ATA has the expertise required to select the correct type for the desired application as well as correct bolt sizing and numbers.
- Bonded – using adhesive to make a structural connection requires special considerations. From environmental temperature impacts to correct material properties, we have dealt with adhesive-critical joints in industries ranging from aerospace to sporting goods.
Detailed Design for Manufacturability
Good detailed design involves knowing how to bring a product into a production ready state. Designing for manufacturability leads to cost control, schedule deadlines being met, reduced lifecycle costs, and a plethora of other benefits. Below are some of the areas that are encompassed within this field of knowledge and that ATA has expertise with:
- Material selection – choosing the right fabrication material can have a variety of impacts. Product life expectancy, environmental survivability, and ease of manufacturing are just a few of the areas that material selection can impact.
- Member sizing and optimization – using our analysis-driven design expertise, ATA ensures that products are not over-designed to the such an extent that the design is inefficient. Optimization programs such as Altair’s Optistruct are used to ensure that product material and costs are minimized while still meeting the complete design intent.
- Engineering drawings – creating accurate engineering drawings of a design is pivotal in guaranteeing that the product is built to the desired design intent. Incorrect drawings can result in unnecessary re-builds as well as cost overruns. ATA has a long history working with machinists and other fabrication personnel. We know what type of information needs to be captured on these drawings in order to make sure that the fabricated product matches the design the first time around.
