Services
From a single gear rating to a validated NVH model of a complete drive. Each service can be booked on its own or combined into a project.
Gear and transmission calculation
Rating and optimisation of gears, shafts and bearings to international standards, with macro- and microgeometry tuned for strength, efficiency, mass and noise.
Typical questions
- Will the gear set survive the duty cycle, with which safety margins?
- How far can we downsize before strength becomes the limit?
- Which microgeometry keeps the contact pattern right across the load range?
What you receive
- KISSsoft and KISSsys calculation models, in native format
- Safety factors for pitting, tooth root bending, scuffing and micropitting
- Optimised macro- and microgeometry, checked by loaded tooth contact analysis
- Manufacturing data (DXF drawings, STEP models) and a calculation report
Standards and tools
NVH and multibody simulation
From transmission error to radiated noise: flexible multibody models of gearboxes and e-drives that show where noise comes from and which change removes it.
Typical questions
- Where does the whine or rattle come from?
- Which housing modes amplify it, and at which speeds?
- Which gear modification lowers it without costing strength?
What you receive
- Campbell diagram with excitation orders and critical modes
- Reduced flexible multibody (RFM) model with gears, bearings and housing
- Transmission error, mesh forces, accelerations at virtual sensor points, equivalent radiated power and sound pressure
- Before-and-after comparison of optimised gears and housing
Standards and tools
Gearbox design
Gearbox concepts and layouts for stationary and mobile machines, from a specification written with you to data ready for a prototype.
Typical questions
- Which layout meets the ratio, torque and space we have?
- Planetary or parallel shafts, and what does each cost in size and mass?
- Can the gearbox be integrated into the machine structure?
What you receive
- Requirements and load spectrum, agreed in writing
- Layout comparison with kinematics and rating
- Detailed design of gears, shafts and bearings, with tolerances and stiffness
- Manufacturing data and support through prototyping with manufacturing partners
Standards and tools
Failure analysis and reverse engineering
Root-cause analysis of damaged gears and gearboxes, and reconstruction of gear data for parts that have no usable drawing.
Typical questions
- Why did it fail: overload, misalignment, lubrication or manufacturing?
- Can a legacy gear be remade from measurements or a 3D scan?
- What has to change so it does not happen again?
What you receive
- Site visit and systematic inspection of components and lubricant
- Rating of the as-built design under the real load
- Reconstructed gear geometry and manufacturing drawing
- Clear recommendations, ranked by effort and effect
Standards and tools

Testing and model correlation
With specialist test partners: modal analysis, vibration and noise measurements, and correlation of simulation models with what the hardware does.
Typical questions
- Does the model predict what we measure on the bench?
- Where should the sensors go to see the problem?
- Which parameters must be updated so the model can be trusted?
What you receive
- Test plan with sensor positions taken from the simulation
- Experimental modal analysis, shaker and run-up tests with partners
- Correlation of accelerations, FFT spectra and surface velocities
- Updated model and a validation report
Standards and tools
Design methods and validated models
Your own design method, written down: parametric models, design-of-experiments studies, validated safety factors and an internal handbook, so your team can repeat the result.
Typical questions
- Which safety factors can we defend for this material and process?
- How do we design the next variant without starting from zero?
- How do new engineers learn the method?
What you receive
- State of the art and requirements for your product family
- Parametric KISSsoft and KISSsys templates
- DOE and sensitivity studies, verified against test results
- Design handbook and training for the team
