Nonlinear equilibrium curvatures and free vibration characteristics of a two-pulley belt-driven system with belt bending stiffness and a one-way clutch are investigated. With nonlinear dynamical tension, the transverse vibrations of the translating belt spans and the rotation motions of the pulleys and the accessory shaft are coupled. Therefore, nonlinear piecewise discrete-continuous governing equations are established. Considering the bending stiffness of the translating belt spans, the belt spans are modeled as axially moving beams.

Applying Newton's Second Law to the hanging mass: ma = mg - T where m is the mass and a is the acceleration of the hanging mass, a is the acceleration of the hanging mass, and T is the tension in the rope. Rearranging, T = mg - ma [eqn 1] The torque on the pulley is given by: and is experiencing a torque of 0.0320 N*m. If the same pulley also has friction, acceleration will be less.

## Dynamic modeling of belt drives using the elastic. - SMARTech

My co-advisor, Dr. Aldo Ferri, for their support and guidance while working on my thesis. I would like to thank my. 14 Stick, Elastic Creep and Fully-Developed Creep Zones for a Flat Belt Drive. 17. 15 Plot of Real Part of. It was found that the solutions to the governing equations with the EPP friction model was similar to. I am trying to model a mass being driven by a motor (Angular acceleration $\dot$ and shaft-polar modulus $J$) with belts and pulleys. This is then being compared to numerical simulations. The system is so: Here, $\tau$ is the torque provided by the motor whose shaft has moment of inertia $J$. Torque may be calculated as $\tau = J \dot$ where the pulley (or sheave) has a diameter of $b$ and hence a radius of $b/2$. The effect of gravity and any slack in the belt is neglected. A viscous force acts with a coefficient of $\nu$ (N/m/s). The horizontal direction is the $x$ direction and the corresponding displacement, velocity ($v$) and acceleration ($a$) of the mass are $x, \dot, \ddot$ respectively. Force balance, where tension in single rope is given by $T$: $$F = m\,a$$ $$3T - \nu \, v = m\,a$$ $$3\frac = m \ddot \nu \dot$$ $\because$ the angular acceleration may be given as $\dot = a/(b/2) = \ddot/(b/2)$: $$3\frac = 3 \frac = 3 \frac$$ $$\therefore m \ddot \nu \dot = 3 \frac$$ or $$\frac\ddot \frac \dot = \frac$$ $$\left[\frac - \frac\right] \ddot \frac \dot = 0$$ The initial conditions for this differential equation are for position and velocity: $x(0) = 0, \dot(0) = \omega b/2$ For the following physical parameters: $m=2000$kg, $\nu=1000$N/m/s, $\omega = 2$ rev per sec, $b=0.1$m, $J=1$kg/sq.m, I use to solve the 2nd order ODE and plot the position wrt time. Clear[m, Ir, b, \[Nu], s, t, \[Omega]]; m = 2000.;(*mass in kg*) Ir = 1.;(*moment of inertia of shaft in kg-m^2*) b = 100*10^-3 (*sheave diameter in meter*); \[Nu] = 1000.;(*Viscous drag in N/m/s*) \[Omega] = N[120/60];(*Rev per second of shaft in 1/s*) \!

## Transmission of Power through Belts | Mechanical Engineering Assignment

Synchronous belt drives are more energy efficient than V-belt drives, providing a cost effective method of improving the overall system efficiency. Energy costs continue to rise. Synchronous belts can provide significant energy savings. Efficiency can be defined by the following formulas As these equations show, energy. Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. Machine components designed to manage forces and movement in this way are called mechanisms. An ideal mechanism transmits power without adding to or subtracting from it. This means the ideal mechanism does not include a power source, is frictionless, and is constructed from rigid bodies that do not deflect or wear. The performance of a real system relative to this ideal is expressed in terms of efficiency factors that take into account departures from the ideal. As the lever pivots on the fulcrum, points farther from this pivot move faster than points closer to the pivot. The power into and out of the lever is the same, so must come out the same when calculations are being done. Power is the product of force and velocity, so forces applied to points farther from the pivot must be less than when applied to points closer in.

Belt drives are simple, inexpensive, and do not require axially aligned shafts. They help protect machinery from overload and jam, and damp and isolate noise and vibration. Load fluctuations are shock-absorbed cushioned. They need no lubrication and minimal maintenance. They have high efficiency 90–98%, usually. Tension in belt spans In the following equations, the application first determines the most suspicious pulley what requires the maximum belt installation tension to transmit a load. Then the belt tension in each span is adjusted for all pulleys accordingly with respect to initial belt installation tension. ” is the actual maximum tension in belt span considered for all belts in the belt drive.

## Physics Tutorial: Frictional Torque

The belt in Fig. P1.52 moves at steady velocity V and skims the top of a tank of oil of viscosity μ, as shown. Assuming a linear velocity profile in the oil, develop a simple formula for the belt-drive power P required as a function of h, L, V, B, μ. What belt-drive power P, in a watts is required if the belt moves at 2.5 m/s over SAE. In the following math applet, change the radius of each pulley and observe the effect on the linear velocity of the belt and the angular velocity of each pulley. Observe that: Also, notice that the ratio of the angular velocities is the inverse of the ratio of the radius of the two pulleys. For example, if r_1=5 and r_2=2 (ratio 5/2), the ratio of the angular velocities is 1.2/3 = 2/5.
