1. FEA- Modal Analysis of Disc horn and Trumpet horn assembly

The automotive part manufacturer approach us to do the FEA analysis of 2 different horn assemblies including their diaphragm, oscillator and other sub component masses, mounting details were also considered during the study.

Output in terms of natural frequencies of diaphragm (Lt and Ht) and Oscillator were provided for various mode shapes and for both the horn assemblies (disc horn and trumpet horn).

2. FEA of a Transport container

Transportation container used for transporting goods, its design was validated using FEA for different load cases and as per ISO 1496-I standard. Several loading cases were analysed like stacking, lifting, strength of container walls, longitudinal and transverse rigidity, lifting from fork lift etc.

Material properties and appropriate Boundary conditions with sufficient pay load were used to check the structural integrity of the container. Linear static analysis showing Von-mises stress contour and deflection contour for each load cases were presented in the report, and necessary design modifications were suggested to limit the stresses within the allowable limit.

3. Engineering design for 2 Axis Tracker

Two-axis tracker system used for solar panels which are driven by two linear actuators, was to be validated using CFD and FEA to meet the operating performance. Wind loads are anticipated as the most critical loading condition that the tracker system must withstand during its operation. It is therefore desired that a detailed analysis should be performed using Computational Fluid Dynamics (CFD) to calculate loads and/or moments coming on individual joints and connection points of the tracker, installed at multiple solar panes in an open area. Additionally, it was also required to verify if the design can withstand the loads from wind speed upto 170 Km/hr.

A Finite Element Analysis (FEA) model of structural and connecting members of the design was carried out to check if the design can withstand added loads from wind during tracker operations. The stress and deflection contours on the structural components and connecting elements helped us in identifying the area of concern design with suggestions on design modifications from our side.

4. Design verification of an AHU units for seismic loading

These AHU units of 10 m * 5m which were to be used in a Data Center building, comprises of many compnonets like fan, coil heat exchanger, and compressor. These units are connected to AHU enclosure with steel bolts. We conducted FEA- finite element analysis is to check attachment of internal components with AHU body and base frame for seismic loading. The kind of loading considered was the deadweight of the internal components, static and dynamic weights, and seismic load as per applicable installation area and as per ASCE 7-10.

Through FEA, the deflections and stresses contours were compared with allowable values as per applicable standards and material allowable and Design suggestions were provided by us, to meet the minimum the acceptance criteria.

5. Root cause analysis for domestic water risers failure in a High Rise building

For every large commercial/ residential building projects, HVAC/MEP piping is a critical system. To prevent the breakdown of this system due to stresses, deflection or loads acting on it during design or operating conditions, the plant room and piping network should be designed with adequate no. of pipe supports, flexible connectors etc. In this case, the customer was facing pipe burst issues in their domestic water supply risers during peak weather conditions in their residential high rise towers having 30+ floors.

These regular issues were bringing a lot of discomfort not just to the building occupants, but also to the building contractors, project management and the service team. We did the survey and root cause analysis, and suggested adequate types and no. of supports. After the installation, pipe bursting didn’t occurred and no complaints were made by the building occupants.

6. The True Vapor Pressure (TVP)

TVP reflects the level of performance of the crude oil at the time of handling, storage and transportation. In API 650 tank, it underlines conditions under which the bubbles may form and shows where pressure build-ups of escaping light ends are likely to happen during the storage.

We are actively involved in various ADNOC and PDO projects in the middle east and performed TVP analysis and Tank emission facilities at their various project sites.

The measurement of TVP eliminates costly damages to the tanks, vessels or pipelines that transport crude oil. In addition, it provides guidance on the crude oil storage and how the transportation facilities should be constructed to withstand a worst-case situation.
