Finite element (FE) model of brake insulator in reducing brake squeal noise for motorcycles

In Malaysia, motorcycles are largely used for people to travel from one destination to another. Motorcycles can be said as a cheap and efficient transport in terms of fuel consumption and less in the traffic jam problem. With a large number of motorcycles on the road, it may create noise and air pol...
