Durability Analysis | Application Of Durability Analysis In Automotive, Aerospace and Wind Turbines

Durability Analysis

Durability analysis involves defect characterization, crack initiation and propagation mechanisms, and long term performance prediction. Durability analysis enables them to identify such points at a very early stage. Such tests can analysis and improve the structural and cyclic strength of a design.

Automotive Durability Analysis

• Design more reliable transmissions, drivelines and axles
• View the whole gearbox as an interacting and flexible system
• Predict gear, bearing and shaft lifetimes in the design concept phase
• Accurately and efficiently compare complex gearbox arrangements or concepts such as AMT, DCT, Hybrid and CVT
• Reduce gearbox weight by using component strength
• Minimize noise and vibration by influencing the transmission error
• Identify the weak points in the whole system under realistic load conditions
• Consider the impact of manufacturing tolerances in the concept design phase
• Improve the bearing choice by unique accurate prediction of bearing behavior
• Interact with dynamic solutions for your full vehicle design
• Predict the effects of generators / engines on the gears and its components in your hybrid system

Durability Analysis in Wind turbine

• Understand and benchmark operating load and extreme load scenarios
• Design gearboxes to meet lifetime targets
• View the gearbox as one complete system, without the need for sectioning and sectional boundary conditions
• Analyze the behavior of complex planetary systems within the whole system
• Accurately predict loads, deflections and interactions of all components
• Calculate detailed bearing behavior to identify excessive loads
• Direct loads or reduce misalignment’s to improve the system quality
• Predict load sharing in the fully flexible system instead of assuming load sharing factors
• Reduce weight and cost without reducing component lifetime
• Minimize noise pollution caused by transmission error

Aerospace

• Improve reliability for critical parts
• Reduce gearbox weight
• Predict bearing behavior under extreme load and climate conditions
• Optimize gearbox size

Off-highway

• Design heavy duty transmissions
• Accurately represent multi-gear mesh situations
• Optimize gearbox weight without compromising durability
• Predict system behavior under misuse conditions
• Compare different lubrication situations
• Precisely define micro-geometries to avoid edge-loading of teeth under extreme load conditions
• Consider a split torque system load

Industrial equipment

• Design for improved reliability in process machinery, material handling, power take offs, speed reducers and production line equipment
• Improve accuracy of high precision machinery by understanding and predicting system and component deflections
• Reduce failures in gears and bearings due to precise prediction of misalignment’s

Consumer and office appliance

• To optimize weight and size of power tools, food processors, washing machines, printers and photocopiers
• Improve product quality by reducing unwanted deflections
• Predict changes of working accuracy over a product’s life
• Design casings that fulfill the requests for look and function simultaneously without wasting material
• Consider new materials for new or existing product concepts
• Create technical documentation for certification
