Using RADIOSS to Reduce the Simulation Time Without Compromising on the Accuracy

In this 45 minute webinar, you will learn: How RADIOSS can use a time step higher than the theoretical one while still respecting the stability condition. How advanced mass scaling (AMS) can be used on complex RADIOSS explicit models. The method dramatically reduces the elapsed time, without modifying the mass of the model or the rigid body translations, therefore providing very accurate results. Examples will we provided to illustrate how the method can be applied on large-scale FEA models. <br/><br/> <i>This is a recording of the webinar that took place on September 12, 2012 </i>

This removes the need to create intermediate FE models of the restraint system, which reduces development time and provides higher confidence in simulation results.

Automotive Modal Testing Support and CAE Correlation Using Altair HyperWorks

To derive the natural frequencies and mode shapes of a given structure, the test Engineer has to decide on excitation positions that will efficiently excite all the modes of the structure in the frequency range of interest.

Using Altair HyperStudy and Radioss (bulk), Pre-test CAE analysis has been carried out to identify effective excitation positions before the commencement of modal testing, thereby significantly reducing pre-test lab time.

Materials and Material Management

When simulation results don’t make sense, what checks do you perform? Besides the modeling aspects of loads and boundary conditions, mesh sizes, right formulations, etc., the most often overlooked cause of problems is the wrong assignment of materials and properties in a solver input deck. In the midst of running many simulations it is so easy to modify values that users forget that what they intended for a part is not what is being analyzed. Identifying the correct material values and assigning them is such a crucial step in your analysis that any mistake can compromise the results and design decisions you make based on simulation.

Applications of Advanced Composite Simulation and Design Optimization

Usage of fiber reinforced composite material entered an new era when leading aircraft OEMs took an unprecedented step to design and manufacture essentially full composite airframe for commercial airliners. Composite structures offer unmatched design potential as the laminate material properties can be tailored almost continuously throughout the structure. However, this increased design freedom also brings new challenges for the design process and software. Moreover, as a relatively new material, composite behaviors are more complex and less fully understood by design engineers. Therefore, reliable simulation for highly complex events like bird strike and ditching can play an important role in shortening the product design cycle. This paper showcases two area of CAE tools for composite applications. On advanced simulation, bird strike simulation with Altair RADIOSS [1] is demonstrated on an aircraft underbelly fairing. On design optimization, an airplane wing structure is designed using an innovative composite optimization process implemented in Altair OptiStruct [1-3]. OptiStruct has seen increasing adoption among aerospace OEMs, as demonstrated in the Bombardier application process described in this paper.

Monash Motorsport takes advantage of optimization and additive manufacturing technologies and wins again!

Since their first Australian SAE Student Racing competition in 2000, the Monash Motorsport team has steadily improved the performance of their race car. Recently the students discovered the benefits of combining Altair‘s OptiStruct optimization technology and 3D printing. Based on an initial prototype rear hub design from the 2013 car, the team proceeded to pursue titanium front hubs and uprights to decrease the car’s unsprung mass. This was a tough challenge, since the former design was already made of lightweight aluminum. To tackle this, Monash Motorsport employed Altair’s optimization technology OptiStruct to design and optimize a titanium upright, which was then produced using additive manufacturing technology from CSIRO. As a result, the students were able to reduce the component’s weight by a further 30 percent whilst maintaining the component stiffness and reducing the development time and costs.

Since January 2013 Volkswagen Motorsport compete at the FIA World Rally Championship with the Polo R WRC. To improve the vehicle performance it is essential to reduce the cars weight and inertia. Drivers perform best lap times when they feeling well in the race car. So you have to meet drivers ergonomically needs. Also passive passenger protection is an important topic. To meet these requirements an own racing seat has been developed.

Topology Optimization of Racecar Suspension Uprights

This was an HTC 2011 presentation given by Billy Wight of Luxon Engineering. This presentation is a case study of applying Altair HyperWorks topology optimization techniques to the design and analysis of racecar suspension uprights. Utilizing manufacturing constraints, stress constraints, and multiple loadcases, topology optimization revealed an optimum material distribution in an efficient manner minimizing development time while maximizing design goals. This optimized design increases stiffness by 225% and reduces mass by 40% versus the original design while meeting stress constraints.

HyperWorks Process Manager Delivers Productivity and Quality Gains to Chassis Design Process

Using Altair HyperWorks Process Manager, M&M was able to implement best practices through standardization of CAE processes and minimize CAE analysis set-up time. Automated post-processing enabled through Process Manager facilitated a 40% reduction in time when compared with the manual practice of post-processing.

Minimising Mass and Increasing Durability of a Vehicle Suspension System Using OptiStruct

Gestamp selected Altair to develop a set of custom tools within HyperWorks, eliminating the need for an initial 'trial and error' design loop while reducing mass and increasing durability of a rear twist beam suspension system. The company achieved a reduction in lead time while producing competitive low cost, low mass RTB designs.

Fatigue Life from Sine-on-Random Excitation

Fatigue life prediction of structures whose natural frequencies lie near the frequencies of the input loading requires the stress results from dynamic analyses. These analyses can be performed in either the time or the frequency domains depending on the nature or the loading. This presentation will outline the approaches available for fatigue life prediction using Altair OptiStruct and APA product, nCode DesignLife for both time and frequency based dynamic analyses. The strengths, weaknesses and assumptions of each approach will be presented, along with typical applications enabling the user to select the proper technique for their particular use case.

Delivering World Class Chassis Design

This paper details the extensive use of CAE optimisation technology at ThyssenKrupp Automotive Tallent Chassis Ltd (TKA). There are a number of trends in the automotive business that are presenting great challenges, these include severe cost pressures from OEM’s, platform commonisation and reduced vehicle development cycle time. The use of optimisation is critical for TKA to maintain its competitiveness, this paper deals with more advanced concepts of optimisation by extending into the severely non-linear region of analysis types.
