END-OF-LINE TESTING AND EVALUATION FOR ELIMINATING THE CAUSE AND THE SYMPTOM DISCOM Analysis For transmissions, electric motors, gearboxes and axles

SIMPLIFYING THE PROCESS Vehicle noise is the sum of its parts, which are many: including power plant, input shafts, axles and all the gears in between. To help you bring the best possible powertrain to the market, DISCOM Analysis uses rotationally synchronous order analysis and averaging to go beyond registering a bad transmission or motor; the system identifies the source of the problem and points to its cause. Once identified, the failure can be traced back to its root cause and mitigated or eliminated. Eliminating problems before they happen improves cost-effectiveness, saves time and increases...

Each test cycle The results of every test run, consists of a number of steps from every test stand in the that generate specific results, for production line, are collected in a large results database. This • 3rd gear speed ramp up database is the anchor point • Torque ramp phase 1 production analysis tool, that • Differential test highlights current production problems, offers trend analysis, helps refine limits, and closes the sequence, or even repeated or loop of continuously enhanced omitted. In each test step all production...

UNIQUE APPROACH TO DATA PROCESSING AND ANALYSIS TasAlyser has numerous display capabilities for evaluation and results TasAlyser software is the data analysis part of the system. It controls data acquisition and processes the signals. Using rotationally synchronous averaging, this software computes one analysis channel for each rotor and each sensor. Signal components of the synchronous shaft are enhanced, while other noise components are attenuated. This provides the acoustical properties and any defects of for each shaft. DISCOM Analysis can process data for 20+ shafts, simultaneously, for...

PROCESSING CHANNELS Channels are labelled based on their function and type, for example, “Input Shaft Sync”. The Mix channel is processed without rotational averaging, so it contains the contributions of all noise sources. Sync channel
