LAB³   Engineering Consulting

LAB³ Engineering has developed a consolidated competence on shock analyses of elastically suspended units (propulsion engines, generator sets, gas turbine, etc.) for naval, military and seismic applications. A shock analysis aims to predict the following quantities:

• Residual acceleration at any given point of the suspended mass.

• Maximum elongations of the flexible mountings supporting the mass, and elastic connections such as couplings and bellows.

• Maximum shock reaction forces exerted by the supporting structure at the resilient mountings locations.

The analysis can be performed either with linear or nonlinear elastic resilient mounting behavior and can also include the presence of shock limiters to reduce the shock elongations.

Our software allows the description of the shock pulse consistently with all the most important shock specifications for naval, military and seismic applications. In many circumstances, only the Shock Response Spectrum (SRS) is assigned as a shock specification. We can synthesize a time-varying foundation displacement consistent with the assigned SRS.
