Crack Detection in an Aluminium Oxide Grinding Wheel by Impact Hammer Tests

Hammer Impact Test Applied for Fouling Detection in Pipelines

Teste de Impacto do Martelo aplicado na Detecção de Incrustação em Tubulações A detecção da incrustação em sistemas de dutos é um problema persistente e requer uma demanda pertinente para as indústrias qúımicas, petroĺıferas, aliment́ıcias e farmacêuticas. A incrustação é um processo de deposição de materiais sólidos dissolvidos orgânicos e outros materiais pesados nos fluidos transportados ou e...

Experimental Study of Sable Crack Growth in Thin Aluminium Sheet

Recent failure information from research teams in NASA Langley and others has shown that CTOA based fracture models calibrated on large C(T) and M(T) specimens can be transferred successfully to cracked aircraft fuselage structures for the assessment of their residual strength. A major difficulty that could limit the more extensive use of this failure parameter is its experimental measurement e...

Topology Optimization of Aluminium Alloy Wheel

A great number of wheel tests are required in designing and manufacturing of wheels to meet satisfactory requirements. The impact performance of a wheel is the major concern. Numerical implementation of impact test is essential to shorten the design time, improve the mechanical performance and lower development cost. Project includes the “Topology Optimization of Cast Aluminium Alloy wheel” usi...

Design of Robust Grinding Wheel Reciprocating Arrangement for Precision Point-grinding Machining

This research is to investigate the dynamic characteristics of the grinding process. A kind of robust grinding wheel reciprocating arrangement is schemed out, which realizes the precise point-grinding machining. The grinding wheel reciprocating movement is driven by a linear motor to replace the traditional crank or hydraulic pressure drive device. Based on the time series method, the modal exp...
