Development of shaker ( mechanical )

Vibration test machine is widely applicable to the defence, aerospace, communications, electronics, automobiles, and other industries. Direct drive shaker is one of types of vibration testing machine that available in industries today. The direct-drive vibration machine consists of a rotating eccentric or cam driving a positive linkage connection which forces a displacement between the base and table of the machine. From multi speeded machines to medium, large and extra-large machines, these machines come in various types and categories, performing a range function. To design and build a small’s scale direct drive shaker that meets a requirement for vibration test machine in industries, fabrication of direct drive shaker will be done in this project by using Scotch yoke mechanism which is a mechanism for converting the linear motion of a slider into rotational motion or vice-versa and DC motor is used to create a rotational movement that will be control by L238D motor driver
