Commercial Vehicle Cab Structural Performance
Assessing cab structural response under regulatory impact loading to support crashworthiness development.
Assess cab response under defined impact loading.
Regulatory impact loading can involve large deformation and load transfer through thin-walled structures, joints and reinforcements.
Follow deformation and load redistribution through the event.
The model represents the impactor and its contact with the cab. Time histories, section cuts and alternate views provide insight into local plasticity, structural deformation and internal load paths.
Support crashworthiness development before physical testing.
Simulation can identify critical response mechanisms and provide a consistent basis for comparing modifications to cab geometry, reinforcement and connections.
Examine internal load paths with section cuts.
Section cuts and views with selected panels hidden expose deformation and load transfer within the cab. These are visualisation choices; the displayed cut or hidden component does not by itself define the modelled configuration.
Detailed insight into cab structural performance.
Non-linear transient analysis provides insight into load transfer, energy absorption and permanent structural deformation, supporting assessment against applicable regulatory requirements.
Load paths & energy absorption
Assess how impact energy is absorbed and transferred through the cab structure.
Intrusion & deformation
Track displacement, deformation and permanent set in critical regions of the cab.
Design comparison
Evaluate the influence of structural reinforcements, cab geometry and seating configurations.
Manikin assessment
Use digital manikins to assess potential encroachment into the prescribed occupant survival space.
Methods behind the case study.
Specialist analysis for cab and protective-structure development.
Engage our engineers for regulatory impact simulation, design comparison or independent review of cab structural assessments.
