Chassis & Weldment Analysis

FEA for Heavy Machinery

Heavy vehicles and massive industrial frames endure extreme torsional stress and asymmetric loading. We apply advanced Finite Element Analysis (FEA) to evaluate the structural integrity of earthmovers, heavy-haul trailers, and continuous mining equipment.

Our specialized engineering matrix analyzes thick-plate weldments, complex castings, and heavy bolted joints. We utilize non-linear material models to accurately predict plastic deformation and ultimate yield failures in multi-ton chassis components before physical prototyping.

Advanced Crane Simulation & Design

EOT Cranes

EOT & Gantry Cranes

Rigorous structural calculations for massive box girders and end carriages. We analyze moving wheel loads, crab skewing forces, and dynamic hoisting factors to prevent elastic buckling in extreme spans.

Offshore Cranes

Offshore & Jib Cranes

Specialized modeling for pedestal-mounted and lattice boom cranes operating in high sea states. We simulate wave-induced vessel motions (heave, pitch, roll) interacting directly with the lifted load.

Crane Codes

Global Code Compliance

Total assurance of regulatory safety. Every structural member, weld, and mechanism is mapped and validated strictly against CMAA 70/74, FEM 1.001, EN 13001, and API 2C load spectrums.

Multi-Body Dynamics

Heavy Vehicle Kinematics

Massive vehicles require flawless interaction between their hydraulic actuators, suspension linkages, and articulating booms. Varun Dynamics utilizes Multi-Body Dynamics (MBD) to simulate the exact kinematic behavior of heavy payload handlers in motion.

We calculate the transient forces acting on pivot pins, trunnions, and hydraulic cylinders during extreme maneuvers—such as a rigid dump truck cornering under full load, or an excavator tearing through bedrock.

Fluid-Structure Interaction

Wind & Seismic Overturning

Tower cranes, ship-to-shore (STS) cranes, and heavy draglines present massive surface areas to extreme environmental forces. We employ Computational Fluid Dynamics (CFD) to calculate wind shear, vortex shedding, and aeroelastic flutter on large lattice structures.

Coupled with Response Spectrum Analysis (RSA), we simulate seismic events to ensure that massive center-of-gravity shifts do not result in structural overturning or catastrophic foundation failure.

Slew Bearing

Slew Ring Monitoring

We map sensor data from giant crane slew bearings directly into our digital models, tracking real-time load distribution and thermal gradients to predict bearing raceway degradation.

Fatigue Tracking

Live Fatigue Tracking

Strain gauge data from heavy vehicle axles and crane girders is constantly fed into AI-reduced order models (ROMs) to calculate the exact Remaining Useful Life (RUL) of the asset.

Predictive Analytics

Predictive Overload AI

Real-time algorithmic detection of abnormal payload swings and P-Delta effects, actively alerting operators to potential tipping moments before they breach the safety envelope.

The Heavy Validation Methodology

01. Load Spectra

Deriving the exact duty classes, lift cycles, and impact factors based strictly on heavy engineering codes (e.g., CMAA Service Classes A through F).

02. Solid CAD

Constructing high-fidelity, parametric 3D geometries of heavy plates, pin joints, hydraulic mounts, and specialized heavy lifting tackles.

03. Heavy Meshing

Hexahedral-dominant meshing specifically optimized for capturing stress singularities around thick structural weldments and massive cast steel components.

04. Solver & Cert

Executing implicit and explicit solvers to finalize von Mises stress contours, culminating in a PE-ready structural validation dossier.

Heavy Engineering FAQs

We utilize non-linear Finite Element Analysis combined with Rigid Body Dynamics to simulate extreme overload test conditions. This includes evaluating the P-Delta effect (where deflections multiply the overturning moment) to ensure the crane structure and slew bearings do not reach yield or tipping points during a 125% proof load test.

Our structural calculations and fatigue life predictions are strictly governed by top-tier heavy machinery codes. For industrial overhead cranes, we use CMAA 70 & CMAA 74. For European and global gantry systems, we adhere to FEM 1.001 and EN 13001. For marine and offshore lifting, we use API 2C.

Yes. We use Multi-Body Dynamics (MBD) to track the exact kinematic pathways of massive suspension struts and steering linkages over simulated rough terrain. The resulting joint forces are imported into FEA solvers to analyze the fatigue limits of the truck's main chassis and heavy payload dump beds.

For equipment presenting massive surface areas—like Ship-to-Shore (STS) cranes and draglines—we utilize Computational Fluid Dynamics (CFD) to calculate exact wind drag coefficients, vortex shedding frequencies, and aeroelastic flutter, ensuring the heavy structure resists overturning in storm conditions.
