Structural Analysis and Model Validation for the James Webb Space Telescope ISIM Structure

The James Webb Space Telescope is a highly sensitive instrument that is positioned using a precise optical metering support structure. This supporting structure is made from composites to reduce thermal expansion effects while reducing weight. The instrument and structure are subjected to temperatures ranging from ambient during launch to cryogenic temperatures while in orbit. Dynamic and static loads are encountered during launch and in operation respectively.


Force Response of a Sun Roof Bearing

Ticona GmbH is a producer of high-performance plastics. It closely supports customers in a large number of key markets customers during their engineering design process. Before implementing material simulation, they faced challenges with correctly modeling fiber reinforced plastic parts, obtaining quantitative and predictive results from FEA, and using a unique material description valid for all ...

Weight Reduction of an Engine Mount

Trelleborg is a global automotive supplier that offers sealing, damping, and protection solutions to the automotive industry. To reach their goal of complying with CO2 regulation, Trelleborg uses material modeling and simulation software.   Challenge To comply with CO2 regulations (2015: 130g   2020: 95g) To reduce the average weight of a car by 200 kg ...

Case Study: Predicting Virtual Allowables

During the process of designing lightweight CFRP structures, one usually needs access to allowable values. However, allowables generation is particularly costly and time-consuming. Each characterized material system must cover various layups, coupon tests, and environment conditions. Each test configuration must be repeated many times to obtain a statistical evaluation of the mechanical property. With advanced ...

Assembly Modeling of Aerospace Structures Using Contact Simulation

Bolted or riveted airframe assemblies are typically modeled as continuous meshes. But advances in meshing and solver technology are changing the way we model these assembly structures. Today, continuous meshes are often replaced by individually meshed parts joined together by some type of connector or interaction definition. These individually meshed parts are typically joined together ...

Structural Analysis of a Tilt-Blade Rotor Mechanism

Question: Given an assembly, such as the rotor mechanism shown below, how can one determine the stresses and potential failure modes? Answer: Nonlinear FEA available in MSC Nastran can be used for structural analysis to assess the behavior of contacting rotor mechanisms. This presentation Contact Model of Rotor Components provides additional details on how to model ...
