Automobiles Component Failures

Failure of automobiles and locomotives can be disastrous. Expensive law suites depend a great deal on technical support from failure analysis experts and their reports.

All moving parts are subjected to wear and consequent temperature elevation. Crankshafts and axles transmit heavy cyclic loads. Hydraulic systems require high integrity in base components as well as connecters. Cooling system failure can initiate a series of Automobiles component failures. We regularly carry out analysis on automobile components failures such as on crankshafts, axles, cylinder liners, radiators and generators for individuals and owners of big fleets of trucks, buses, boats and railways. ITS has dealt with failures related to wear, overload, shocks, impact, overheating, coolant deficiencies and manufacturing defects. ITS has been retained by various legal and private parties as an independent body to carry out failure analysis for settling disputes. ITS often retained by manufacturers to carry out testing and development work for the purpose quality improvement or cost optimization. Evaluation and certification of heat treatment, welds and weld, soldering, plating on Automobiles component manufactured abroad is frequently entrusted to us especially after an inherent weakness has been diagnosed in our failure analysis.

Our approaches for failure analysis may include.

  • Analysis of the material of construction and fabrication
  • Process by which equipment was made
  • Study of component history
  • Visual examination/ fractography
  • Dimensional measurements
  • Macro and Microscopic examination of material samples
  • Mechanical Tests
  • Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Spectrometry (EDS)

Based on all our observations and analysis, client is provided with the detailed report that is conclusive, accurate and well illustrated for technical and non technical readers.

Some of the Automobiles component failure analysis carried out recently include:

  • Failure of truck axles due to heat treatment deficiencies
  • Premature cracking of cylinder liners of fleet of more than 50 buses due to cavitation
  • Failure of a V6 crankshaft of a fishing boat due to bearing failure
  • Chronic failure of radiators on a fleet of buses due to manufacturing deficiencies
  • Premature failure of generators of a large number of city buses.
