Abstract At IBM Systems, developing reliable and robust designs of supercomputers is critical to IBM’s vision and continuing its leadership in our industry. Shorter development cycle time, increasingly dense product designs, along with advanced design features create real challenges in predicting structural performance of servers, such as the recently refreshed IBM Cognitive Systems’ POWER9 portfolio of servers. Both 4U and 2U versions have DDR4 RDIMM’s, POWER9 HLGA processor modules, PCIe Gen3 and Gen4 slots, blowers, hard drives, and internal storage controller slots. To meet IBM shipping standards to ensure POWER9 system’s reliability and design robustness, ANSYS Mechanical and LS-Dyna FEA models were developed and physical tests were conducted. The ability to apply accurate predictive engineering methods using simulation early in the design cycle predicted the structural performance of the servers and shortened its development time, reduced number of physical builds, and therefore, reduced development cost.

Automobile styling design is an important part of the design chain. In the traditional automobile modeling evaluation, the process of project evaluation is more in-depth, and designers exchange ideas. Different designers have different evaluations of automobile styling. The evaluation process lasts a long time, which leads to the design cycle being too long and the efficiency of automobile modeling evaluation is greatly reduced. The introduction of virtual reality in automobile modeling evaluation can effectively optimize the evaluation process and promote the rapid adjustment of the model on the basis of development. From the virtual reality system based on mechanical engineering, we only need the parameters of the car model to observe the actual situation through VR technology, and use the measurement tools to directly and accurately evaluate the driver’s field of vision. Through the application of virtual reality technology in the automobile design stage, the interactive and network-based remote research on automobile modeling will also make the automobile design process more convenient, easier to communicate with designers, and reduce the development cycle and cost of automobile design.

3D Software

In the study, a five-speed manual transmission of commercial vehicles is modeled and assembled with three-dimensional (3D) software SolidWorks. In order to analyze the kinematic and dynamic performance of the manual transmission, its 3D model is imported into the software ADAMS and the Hertz elastic contact theory is applied to calculate the contact force and deformation of the meshing gears. Finally, the speed and meshing force of the meshing gears have been obtained, which are consistent with the actual situation. This method can provide guidance for the design of the key components of the transmission, and thus can shorten the development cycle and reduce the development cost of the transmission.

This article highlights the acoustical analysis changes made by manufacturers in design cycle. Acoustical simulation is being pushed from experts to designers, following the trend for the last 15 or so years that saw other types of engineering applications like finite element analysis and computational fluid dynamics become integrated with computer-aided design packages used by mechanical engineers. With the advent of software packages that allow for design and for acoustical analysis in tandem, design engineers are increasingly running these analyses early in the development cycle and are making design changes to decrease noise and vibration issues they find. Experts suggest that with speaker sound quality and other pertinent information in hand, designers can actually design from the get-go with that information in mind, resulting in fewer design changes down the line. Though early acoustical simulation is still perhaps one of the consumer electronics’ industries best-kept secrets, that’s likely to change as word gets out about the many advantages of front-line simulation.

Cockpit Design

The use of virtual reality (VR) to provide a higher fidelity simulation environment earlier in the design cycle of a new cockpit has benefits in development cost and time, but practitioners may have concerns that use of virtual environments may change feedback. In this work, we aimed to test our VR environment against a non-VR simulator in a mock design study to evaluate if and how subject feedback and performance changed. Two separate groups of subjects evaluated the same two designs, one group using VR and the other a touchscreen desktop simulator. The results indicate that both groups provided similar qualitative feedback on the two designs. Some quantitative performance measures changed between groups, but conclusions made from comparing designs within groups was consistent. We describe our findings on which quantitative measures are best for evaluation in a virtual environment.

The noise of interior plastic parts has been one of the major driving factors in the design of automotive interior assemblies. This phenomenon is one of the major contributors to the perceived quality in a vehicle. The noise is caused by interior plastic parts and other parts as a result of permanent deformation. Traditionally, noise issues have been identified and rectified through extensive hardware testing. However, to reduce the product development cycle and minimize the number of costly hardware builds, hardware testing must rely on engineering analysis and upfront simulation in the design cycle. In this paper, an analytical study to reduce permanent deformation in a cockpit module is presented. The analytical investigation utilizes a novel and practical methodology, which is implemented through the software tools, ABAQUS and iSight, for the identification and minimization of permanent deformation. Here, the emphasis is on evaluating the software for issues relating to the prediction of permanent deformation. The analytical results are compared with the experimental findings for two types of deformation location and the qualitative correlation is found to be very good. In this study, we also develop a methodology to design the guide and mount location of cockpit module for minimizing the permanent deformation. Nonlinear finite element analysis has been implemented and integrated with sensitivity-analysis techniques to minimize the permanent deformation at the areas of interest. Finally, we find the optimal guide and mount locations that reduce the permanent deformation.

Original equipment manufacturers are looking for ways to reduce the product development cycle. A tool to reduce this time in the design of air conditioning systems is introduced in this paper. This is done by using a semitheoretical model of each of the components of a system. The semitheoretical model has the advantage of reducing the number of geometrical inputs that need to be specified when compared with a “theoretical” model. This paper focuses on the most complex of the components—the evaporator. A tube and fin evaporator was successfully modeled and validated. The model was tuned using supplier component data (Luvata, 2005, Heatcraft Evaporator—Version 3.07.05.122 B-DHLEX.EVP) for the evaporator. The tuned accuracy of heat transfer rate and pressure drop, both air- and refrigerant-side, was within 5% over the range of conditions representative of air conditioning applications.

In the design of corn combine harvester, there is a high demand for customization and diversification in China. Aiming at the problems of backward design method, lack of design knowledge and long product development cycle, the discrete beam method is used to establish the corn plant model. The model of sub-device and the vertical and horizontal roller picking device is established by using UG, and the virtual prototype model is established by using ADAMS software. Meanwhile, the simulation experiments on the kinematics and dynamics performance of the separating device, the corn plant and the picking roller are carried out, and the simulation results are verified by field experiments. Through this method, the design parameters of the separating device and the picking roller are serialized, the method of evaluating the separating performance and the picking performance is provided, and the development and design cycle is shortened, which provides certain reference and theoretical basis for the development and design of the corn harvester header.

Silicon nitride and silicon nitride based-ceramics are now well known for their potential as hightemperature structural materials, e.g. in engines. However, as is the case for many ceramics, in order to produce a dense product, sintering additives are utilized which allow liquid-phase sintering to occur; but upon cooling from the sintering temperature residual intergranular phases are formed which can be deleterious to high-temperature strength and oxidation resistance, especially if these phases are nonviscous glasses. Many oxide sintering additives have been utilized in processing attempts world-wide to produce dense creep resistant components using Si3N4 but the problem of controlling intergranular phases requires an understanding of the glass forming and subsequent glass-crystalline transformations that can occur at the grain boundaries.
