Engineering Service: Vibration Analysis, Simulation, Consultancy / (c) Laschet Consulting

Overview of Engineering Services

Vibration Analysis, Simulation, Consultancy, Customer Training + Seminars

The ENGINEERING activities as supported by Laschet Consulting cover extensive CAE ana­lyses (CAE = Com­pu­ter Aided Engineer­ing) to provide calcu­lations (compu­tations) and analyses in order to determine the dyna­mic beha­vior of drive systems in rotating machinery and vehicles. These CAE services are supported by suitable simu­lation soft­ware tools („Virtual Engineer­ing“).


Our major CAE analyses are dedicated to the following studies:

  • TORSIONAL VIBRATION ANALYSIS of complete drive systems

Such jobs can be done very quickly in smaller projects but also as part of com­prehensive CAE studies within R&D or virtual engineer­ing projects – always according to customer require­ments. Confidentiality agreements are, of course, strictly observed.

  • CAE model generation of complete drive­lines (generating digital computer models supported by power­ful soft­ware tools: ARLA-SIMUL, ITI-SIM, SimulationX, ARMD)
  • CAE analysis (simulation) including evaluations
  • working out alternative system con­figurations (drive­line matching)
  • trouble shooting (in case of failures), root cause analysis (RCA), support of machine diagnosis, expert reports
  • summary of improve­ment activities, para­meter studies, optimi­zations
  • inter­pretation, overall evaluation, and documen­tation of the results
    including testing methods, and measure­ment results as part of the final evaluation
  • technical report in English (or German) language (also as a brief report)
  • further customer consult­ing (on site or via online meetings and video conferences)
  • customized trainings, or general training courses, or our annual international engineering seminars
  • worldwide engineering service using online communications

Application Areas

Mechanical + Plant Engineering, Automotive, Shipbuilding, Aviation + Aerospace

Based on considerable experiences for more than 40 years many jobs could be realized with great success as part of a virtual product develop­ment process. See the following reference examples taken from the drive tech­nology:

  • all types of compressors:
    turbo/centrifugal compressors, reciprocating compressors, screw compressors
    according to API 617, 618, 619

  • turbomachinery
  • pump drive systems according to API 610
  • generator drive systems
  • venti­lators (fans, blowers) drive systems according to API 673
  • extrusion machines
  • crushing machines (e.g. cement mills)
  • rolling mill drives
  • drivelines (powertrains) of vehicles (cars, trucks, motorcycles, special-purpose vehicles) with clutches, transmission, special dynamic analysis of E-drives, NVH studies concerning noise-vibration-harshness caused by powertrains
  • ship drivelines including engines or electric motors; com­plete drive systems optionally with auxiliary drives / P.T.O.), influence of the propeller dynamics
  • agricultural machines including attached units
  • rail vehicles
  • drive systems in the aviation and aerospace industry, test stands for heli­copter trans­missions
  • any other industrial drivelines with motors, engines, couplings, clutches, transmissions, gear stages, univer­sal shafts, etc.
  • configuration of drive elements within test rigs / test stands / testing machines and correlation with test signals, drive­line matching: test rig vs. drive­line as built-in

Engineering Service as a Teamwork

In many CAE projects a professional team­work of specialists is crucial. That is why Laschet Consulting cooperates with external engineering & measure­ment partners; go to our special site “Cooperation Partner” for more details.
