5.1 touches base on a double mass spring damper system. The objective is to understand the response of the system when an external force is introduced. In this case, we are interested to find the position and velocity of the masses. The first step is to develop a set of equations for ...
It causes some error in measurement when a simple formula of estimating mass is applied. To eliminate such an error, a new formula is derived to estimate the mass independently of the position of the trajectory that is determined by the switching positions in the relay actions. When the ...

A mass (1.20 kg) is attached to a spring (k = 790 N/m) which is mounted onto a wall. This mass is on a frictionless horizontal surface. You apply a CONSTANT force to the mass while the spring is in the unstretched position and the mass comes to a momentary stop in 1...
Semi-Analytic Solution to Equation of MotionMathematicaBy combining a pair of linear springs we devise a nonlinear vibrator. For a one dimensional scenario the nonlinear force is composed of a polynomial of odd powers of position-dependent variable greater than or equal three. For a chosen initial...
The model consists of a nonlinear ordinary differential equation for the mass-spring-damper system and a differential inclusion for the granules rearrangement function. A numerical algorithm for the problem is presented and simulations of the system behavior depicted. In particular, the changes in the...
Mass Spring System(弹簧系统)
How can the motion of a mass-spring system be described mathematically? The motion of a mass-spring system can be described using the equation x = A cos(ωt + φ), where x is the displacement, A is the amplitude, ω is the angular frequency, and φ is the phase constant. This equa...
