It is a question of studying the dynamic behavior of landing gear (LG) of a F18 landing. To simulate the behavior of the system we use the figure below. The term 'm_{wheel'} denotes the total mass of the constituent members of the wheel. We want to know the displacement 'x_{plane}(t)' of the mass 'm_{plane}' for different scenarios. We consider that the state of the airstrips can be represented by an entry 'y(t)' which simulates the real geometry of the roadway. The tire is modeled by a linear wheel k and a shock absorber wheel c. You are asked to: 1. Establish the dynamic equations of system operation; 2. Model the detailed block diagram of the system; 3. Deduce the expression of the transfer function: H(s)= X_{plane}(s)/Y(s) , the initial conditions being assumed to be zero;
In this solution some basic concepts and formulas of Vibration Mechanics are used. For more information, refer to any standard textbook or drop a comment below. Please give a Thumbs Up, if solution is helpful.

.matlab Objective: This activity has the purpose of helping students to to use either Simulink or VisSim to simulate the system behavior based on its Block Diagram representation and plot its response. Student Instructions: The following spring-mass-damper system has no external forcing, that is u(0)-0. At time t- 0 it has an initial condition for the spring, which it is distended by one unit: y(0)-1. The system will respond to this initial condition (zero-input-response) until it reaches equilibrium. 0)1initial condition...
Create a MATLAB script An engineering company is designing and testing a car suspension system. The system has a conventional suspension design, consisting of a shock-absorber and spring at vertical speed (ie. up and down motion) of the wheel, and the spring's resistance is proportional to the vertical displacement of the wheel. The company would like to investigate how the actual performance of the suspension system compares to that of theory. Dynamic theory states that the equation of motion of...

An engineering company is designing and testing a car suspension system. The system has a conventional suspension design, consisting of a shock-absorber and spring at each wheel. The shock-absorber provides a damping effect that is proportional to the vertical speed (i.e. up and down motion) of the wheel, and the spring's resistance is proportional to the vertical displacement of the wheel. The design team analyses the suspension system in two separate parts: Part 1 - dynamics of the spring-damper system;...
