# Kinematic analysis:Application of defining path of joint

• marellasunny
In summary, kinematic analysis involves defining the path of a joint in a mechanism, such as in the case of a 90 degree double piston mechanism. Engineers use this analysis to determine the path, velocity, and acceleration of the piston. However, for more complex mechanisms, an analytical method may not be feasible and software is often used instead. This is similar to how engineers analyze structures, where not all analyses can be simplified to basic calculations.

I understand that defining the path of a joint in a mechanism comes under the category of 'kinematic analysis'. I do not understand why engineers do this,when all they need to know is the path of the piston,piston velocity and piston acceleration(kinematic analysis). Take for example this 90 degree double piston mechanism -http://www.youtube.com/watch?v=X76HrTygEFQ

Also,is there a analytical method that exists to find the path of joints in a mechanism in motion? Deriving the curve mathematically seems tough.

Not every mechanism is a piston going back and forth. Some mechanisms are quite complicated to analyze, which is why engineers use software to aid in the analysis. It's similar to analyzing a structure. Not every structural analysis can be reduced to analyzing an equivalent beam or beams. Beyond a certain point, the math gets too tedious.

## 1. What is kinematic analysis?

Kinematic analysis is a method used to study the motion of objects, specifically in terms of position, velocity, and acceleration. It involves analyzing the path and speed of an object's movement, usually in relation to time.

## 2. How is kinematic analysis applied to defining the path of a joint?

In kinematic analysis, the path of a joint refers to the trajectory of the joint's movement. By studying the position, velocity, and acceleration of the joint, we can determine its path and understand how it contributes to the overall movement of an object or organism.

## 3. What tools or techniques are used in kinematic analysis?

Kinematic analysis uses a variety of tools and techniques, such as motion capture systems, video analysis, and mathematical equations, to track and analyze the movement of objects or organisms. These tools help to accurately measure and record data that can then be analyzed to gain insights into the kinematics of a system.

## 4. What are some applications of kinematic analysis?

Kinematic analysis has various applications in fields such as biomechanics, robotics, and sports science. It can be used to study the movements of athletes, analyze the motion of robotic systems, and understand the mechanics of human movement to improve performance and prevent injuries.

## 5. How does kinematic analysis contribute to our understanding of motion?

Kinematic analysis allows us to quantify and analyze the motion of objects or organisms, providing a deeper understanding of their movement patterns. By studying kinematics, we can identify patterns, trends, and relationships in motion, which can help us predict and control the movements of systems or organisms.
