Finite Element Model and Modal Analysis

Finite Element Model and Modal Analysis

A spacecraft manufacturer requires a larger sized tank to accommodate increased launch vehicle payloads. HEA constructed a finite element model and a modal analysis and response spectrum analysis were performed. The new design was shown to meet minimum frequency and...
Energy Storage Unit Finite Element Model

Energy Storage Unit Finite Element Model

HEA was asked to analyze this Energy Storage Unit for dynamic loads experienced during rocket launch into orbit. Our analysis revealed that ESU configuration modification was necessary to withstand the launch dynamic loads. Practical modifications were recommended to...
Finite Element Thermal Model

Finite Element Thermal Model

This is an experimental countermeasure device that is watertight and contains high energy battery and transducer electronic systems. The client was concerned that it may overheat during operation. HEA built a finite element thermal model of the electronic assembly and...
Shock and Vibration Load Analysis Model

Shock and Vibration Load Analysis Model

A manufacturer had built a partial finite element model of the complex solid state transmitter assembly, but was unable to obtain useful analysis results because of the model’s complexity. HEA developed an accurate and useable finite element model of the SSTx....
Load Transfer Vehicle Prototype

Load Transfer Vehicle Prototype

Design of a vehicle for transferring pallets and containers weighing up to 60,000 pounds to and from a supply ship via a loading ramp was required. The vehicle was to remain level and maneuverable in spite of ramp slope variations. HEA designed a prototype load...
