Overview

Industry overview

Defence equipment has to survive conditions that are hard and costly to test: blast pressure, shock, sustained vibration on vehicles and ships, and wide temperature swings. Simulation shows the design team the weak points early, so fewer physical qualification tests are needed and fewer of them fail.

Shirsh Technosolutions has worked on defence programmes including blast loading of submarine panels. We use ANSYS Mechanical with explicit dynamics for blast, impact and shock, and ANSYS Fluent for thermal and airflow problems in electronics shelters and enclosures. Most of this work is under NDA, so project details are shared only with the customer's permission.

The terrain

Industry challenges

Blast and shock loads that act within milliseconds and need explicit dynamic analysis

Vibration and shock qualification to MIL-STD-810 and customer test specifications

Tight weight limits on shelters, enclosures and vehicle-mounted equipment

Confidential data, which limits what can be shared outside the project team
