changes in engines and generators

Engineering services

Innovative SMT transmissions

SMT deliver advanced driveline engineering solutions for all automotive applications.

SERVICES INCLUDE:• Concept design & feasibility

• Detailed transmission design & analysis

• Power density improvements

• Gearbox weight & cost reduction

• NVH troubleshooting

• Gear & transmission manufacturing process

optimisation

• Test lab planning & test rig design

APPLICATIONS INCLUDE

• Cars, trucks, buses & off-road vehicles

• Different transmission configurations: manual (MT), automatic (AT), automated manual (AMT) & dual clutch (DCT)

• Axles & transfer cases

SMT have developed a range of innovative, patented, bus and truck transmissions.

When compared with the best existing designs from other manufacturers, the SMT designed gearboxes have a number of significant advantages:

• Increased torque capacity compared with gearboxes of the same weight & size.

• Smaller package size (in particular shorter length

compared with gearboxes rated at the same weight &

power

• Lower manufacturing & maintenance costs

• Comparable or better synchroniser lifetime, NVH, shift

quality & transmission efficiency

Noise and rattle in modern enginesThere is a rising trend in modern petrol engines opting for gear transmission due to the efficiency benefits in trade for noise and vibration issues.

► DRIVA for Engine solves NVH issues raised by gear components in any type of engine

► Predict gear rattle by analysing gear flank contact with backlash

Calculate fatigue life under transient torque changesDRIVA for Engine predicts dynamic torque for any engine operating condition taking into account the complex internal damping and phasing that occurs in a drivetrain.

Simulate dynamic transmission behaviour and the performance of components under variable loading in engines with gear transmissions and belt drives as well as petrol and diesel generators.

Conventional fatigue calculations are problematic as they can seriously over-estimate fatigue life. These are based on a fixed or static torque when in reality this is highly variable over time.

The DRIVA Series is an innovative solution for the full modelling and dynamic analysis of complete drivetrains. Based on a full six degrees of freedom flexible multibody dynamic approach, DRIVA is the first solution designed specifically for the analysis of highly time-dependent load conditions of geared mechanical systems.

Key benefits of the DRIVA Series include...• User-friendly and intuitive interface

• Powerful Multibody Dynamic solver with design tools & analysis capabilities in a fully integrated CAE environment for the accurate and rapid design of transmission systems

• Full-system simulation of any transmission system configuration to provide an accurate prediction of gear, bearing & shaft rating taking into account misalignment

• Comprehensive gear tooth contact pattern & root stress analysis & optimisation

• Accurate prediction & extensive reporting of loads, stresses & transmission errors

• Rapid prediction of key performance characteristics enabling the identification & correction of potential failure modes early in the product development cycle

• Customised reporting of design & analysis results

• Provides a virtual testing environment throughout the design process from concept to production
