Towards this we have
Optimisation of gear box of fast attack craft (FAC).
Gear box designed had excess weight. ProSIM has conducted multi-body dynamic analysis to determine the dynamic forces induced on the gear box housing bearing locations, carried out dynamic stress analysis using finite element analysis (FEA), determined the fatigue life (durability). Using parametric optimization techniques, ProSIM optimized the number, size, and shape of ribs, thickness of housings, and obtained the needed weight reduction without compromising on the performance conditions of deflections, vibration, noise, and fatigue life. ProSIM provided FEA consultancy services that helped customer get his product approved by the end user.
Structural Integrity and Thermal Management Assessment of Sensors used in Spacecraft
ProSIM has worked on several sensors for variety of space applications including missions of Chandrayan and Mangalayan. Sensors are virtually tested for extreme conditions using finite element analysis based simulations. Modal analysis, quasistatic stress analysis, random vibration analysis, sine, bump, shock analysis, thermal analysis including conduction and radiation heat transfer, thermal shock analysis, were conducted using appropriate FEA models. ProSIM has worked as partners with ISRO for FEA outsourcing consultants.
Contact Stress and Contact Area Calculations in Mating Gear Pairs
Accurate contact stresses computation is very important to determine the contact area, which in turn will determine the noise, wear, fatigue, life, etc.
ProSIM has expertise to calculate the contact stresses accurately using non-linear finite element analysis (FEA) by adopting accurate sub-modeling procedures. Figure shows the contact stress graphs. The graph of contact stress shows disparity in contact stress calculation if an appropriate sub modeling procedure is not used. ProSIM assisted customer to design the gear box for longer life and lower noise. ProSIM engineers worked as finite element analysis consultants and solved this critical problem to customer.
Vibration Order Analysis – Campbell diagram of gear box
Gear box vibrations are analysed using FEA and multibody dynamic simulations. 2D and 3D Campbell diagrams are plotted. Critical RPM for gear pair that causes high vibrations is identified. Interpreting the results of FEA, and MBD simulations, cause of high vibration (and noise) was analysed and eliminated.
Coupled Electro-magnetic-thermal-structural analysis of transformers
ProSIM has worked with many transformer companies to predict stray losses, temperature rise, effect of cooling media, thermo-mechanical stress generation, vibrations to optimize the thermal and mechanical structures using FEA. ProSIM has also used finite element analysis to study the transportation load cases including road, rail, ship, and aircraft as per codes of practice in various geographies. Provides finite element analysis and Multiphysics simulation based design verification and design optimization services to electrical machinery companies involved in making motors and drives, generators, alternators, transformers, sensors etc.
