Relative Motion Analysis - Acceleration

Relative Motion Analysis - Acceleration

A slider-crank mechanism converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider. The movement of the slider-crank is an example of general plane motion as the fluctuating angle between the crank and the connecting rod. Consider a segment AB where point A is at the end of the slider and point B is on the diametrically opposite end to point A, on a crack. The variance in...

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. Consider a lifting tong carrying a 100 kg load. It comprises movable sections DAF and CBG linked together with member AB.

Machines

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. One example of a machine is the cutting plier, which is used to cut wires by applying forces to its handles. When equal and opposite forces are exerted on the handles of the cutting plier, they cause the cutting edges to come together and apply equal and opposite reaction forces on the wire, which are greater than the applied forces.

A toggle clamp is a mechanical device commonly used for holding and clamping objects in various applications, such as woodworking, metalworking, and assembly operations. Consider a toggle clamp subjected to a force of 200 N at the handle. The vertical clamping force can be calculated, provided the dimensions of the toggle clamp are known.
The toggle clamp system is a machine structure consisting of movable, pin-connected multi-force members that form a stabilized system to transmit forces. The...

Stability of structures

Stability of structures

In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Mechanism of Ciliary Motion

Mechanism of Ciliary Motion

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Area of Science:

Biomechanics and Robotics
Orthopedic Engineering

Background:

Continuous Passive Motion (CPM) devices are crucial in rehabilitation.
Existing CPMs often lack precise alignment with the human knee's unique kinematics.
Accurate kinematic replication is essential for effective post-operative knee recovery.

Purpose of the Study:

To develop an exoskeleton Continuous Passive Motion (CPM) device for the knee.
To achieve kinematic replication of the human knee joint, including range of motion (ROM) and instant center of rotation.
To enable precise alignment and natural movement during CPM therapy.

Main Methods:

Kinematic interpretation to design the exoskeleton knee joint.
Measurement of knee joint torque during CPM usage.
Application of measured torques to refine the exoskeleton's design.
Development of an exoskeleton CPM with anatomically accurate joint alignment.

Main Results:

The developed exoskeleton CPM demonstrates precise alignment with the human knee joint.
The device successfully replicates the human knee's range of motion (ROM) across various positions.
The design incorporates the instant center of rotation for natural joint movement.

Conclusions:

This novel exoskeleton CPM allows for accurate alignment with the human knee.
The device ensures the same range of motion as the natural human knee.
This technology offers improved CPM therapy through precise kinematic replication.
