TRANSMISSION ANALYSIS

Antonov employs an analysis led design process. The use of world leading commercial and in-house CAE software tools allow Antonov engineers to search the entire design space for the optimal solution early in the design process. Advanced durability and NVH analysis mitigates against technical risk, reduces the requirement for physical hardware testing, and reduces the potential of late emerging issues in the development program which are costly and time consuming to remedy.

DURABILITY ANALYSIS OF SHAFTS, GEARS & BEARINGS

Antonov’s approach to the analysis of rotating gear systems begins early in the design process. Shafts, gears and bearings are analysed as part of the full transmission system enabling correct specification prior to detailed design effort. We have a wide range of experience with planetary and parallel axis transmissions both on client programs and Antonov’s own transmission products. Typical analysis scope includes full system deflections and accurate life predictions for gears, shafts and bearings against defined duty cycles. Software: RomaxDesigner

FINITE ELEMENT ANALYSIS

Antonov has extensive finite element capability for the analysis of complex components. Typical scope includes stiffness, durability and NVH analysis for transmission casings, differential housings, planet carriers, gear bodies, complex shafts, powertrain mounting brackets and shift mechanisms.
Software: Altair Hyperworks / MSC Nastran / Abaqus

STRUCTURAL OPTIMISATION

Whilst conventional finite element analysis is invaluable in accurately analysing fully detailed components, structural optimisation can yield significant benefits and time savings when utilised early in the design process to drive the design. Stiffness, strength and dynamic targets are combined with packaging information to optimise weight and cost, particularly for complex castings such as housings.

NVH ANALYSIS

As vehicles become increasingly refined, reducing transmission noise is becoming ever more critical. Antonov can minimise radiated noise by reducing both the sources of excitation and the dynamic response of the entire system including gear bodies, shafts, bearing pre-load and housing response.

DYNAMIC SIMULATION

Mathematical modelling, analysis and simulation of complete systems and subsystems based on principles of physics. The models created are used for transient analysis to understand the system characteristics. They can also be used for sizing and synthesis of systems and subsystems. Modelling and simulation also form an essential part of control system development.
