【最適化例題】OptiStructで特定の固有周波数を取り除く例題

ある部品の固有振動数を検討するとき、その部品の近傍にモーターなど、特定の周波数で動作する振動源があれば、振動源の周波数付近に固有振動数を持たないように設計したい、ということが考えられます。
OptiStruct の基本的な使用方法で行うのであれば、1次固有振動数を、振動源の振動数よりも大きくするという方法が、考え付きます。OptiStruct の使用方法としては最も簡単な方法ですが、部品の剛性を上げることになり、コストの増加を招くかもしれません。そのため、この方法を選択したくない場合もあるでしょう。
そこで、本書では、OptiStruct を用い、振動源の周波数付近のみに、固有周波数を持たない解を求める例題を示します。

Select PD case study

Kanto Auto Works, Ltd. is a core member of the Toyota Group, developing and producing Toyota vehicle bodies. The company’s organic-material engineering department evaluates and develops plastic parts to be used in vehicle bodies. In the initial stage of development for large plastic parts, such as instrument panels, rigidity and heat resistance are verified using computer aided engineering (CAE). While plastic is significantly lighter than metal and can be molded into complex shapes, deformation, such as warping from external force or thermal expansion in high temperatures, also occurs easily. In order to make parts lighter while still ensuring sufficient rigidity and heat resistance, there is a need to identify which areas require reinforcement.

HyperWorks in the Development of Aeronautic Sensors

Esterline Advanced Sensors is a leading provider of aeronautic sensors. At the company’s French site in Bourges the engineers are in charge of the complete development process of these sensors. The team consists of 5 engineers, who have the entire responsibility for the process of modeling and ensuring FEA reliability so that safety margins can be determined. Each sensor is a specific project for one customer. The design of a new sensor starts with the customer’s specification according to his individual requirements. For the development of a new sensor Esterline has to conduct intensive simulations to ensure to meet the needs. Multiple iterations on design changes are often required to define the optimal sensor design - from the CAD simplifications (removal of non-functional fillets, gaps, non-functional holes, even the modification of complex shapes that have no significant influence on the mechanical behavior) up to the final FEA, through the test results analysis (vibration results in terms of resonances, mode shapes and transmissibility’s, stress measurements via strain gauges …) and parameters fitting. To streamline the development process and to accelerate the model creation process, Esterline Advanced Sensors is applying HyperWorks and especially HyperMesh in the development of its aeronautic sensors.

Global Appliance Manufacturer Mabe Analyzes Spin Cycle with HyperWorks to Improve Washing Machines and Bring Them to Market Faster

Typically when engineers consider the most complex problems involving multi-body dynamics, hydrodynamics, and noise-vibration-harshness, they are focusing on the complexities of automobiles or aircraft. Design issues that can be just as challenging, however, impact every household’s laundry room. For companies like consumer goods manufacturer Mabe, simulation has helped them better solve product issues such as balance ring distortion, move products to market faster and reduce cost.

Daimler - Calculation of Optimal Damping Placement in a Vehicle Interior

One of the most difficult jobs of a NVH Analyst is to sift through a seemingly endless set of results and find the key conclusions that will improve a design. Different assumptions and different subsets of data can give very different conclusions. This paper compares acoustic results calculated for a Class 8 heavy duty truck cab to choose an optimal configuration of damping material. The design was evaluated for structure and air-borne inputs, but only structure-borne inputs are considered in this paper.

Lighter, Better, Faster – HyperWorks in the Construction of Formula Student Cars

The Formula Student Racing Team Elbforace is the racing team of the Technical University of Dresden. The team develops, designs, and manufactures every year a racing car that competes with 270 teams from all over the world at the Formula Student competition. In the season 2010/2011, the team decided to switch from a combustion engine to an electrical powertrain concept. Due to the additional weight that the electrical concept causes, i. e. due to the use of accumulators and an AC converter, the design of the remaining components of the car had to be optimized to still reach a minimum weight for the complete vehicle. The
”With HyperWorks we have been able to compensate the additional weight brought in by the use of an electric powertrain concept. With their software solutions, seminars, tips and valuable support, Altair helped us to reach the given weight and stiffness goals for our car.”
Philipp Heitzig, Elbfloraceteam used HyperWorks for meshing, finite element analysis, and for optimization tasks. Thanks to OptiStruct the team achieved significant weight savings with the redesign of the components, including full composite parts optimization.
