The acceleration of a geared system

APPLIED MECHANICS LABORATORY REPORT Title: The quickening of a geared system Aim: To starting out the scheme on the prediction of the drive of rotors committed by gears. Object: The main goal of the experiment is:         To investigate the theory on the prediction of the motion of rotors connected by the gears.         By the locomote free weight method acting to mensurate the inactivity on all(prenominal) shaft.         Determine the resembling inertia of the system at the appetizer shaft, by the get down weight method. Test rig figure: The rack up of teeth on apiece gear: N =90, N =30, N =90, N =90 Theory: In order to evaluate the homogeneous inertia on each shaft by the Falling Weight method. The vaporise body diagrams reveal: P*R=I*a+Tf Should be a straight problem graph of P*R plotted against a. The intercept should happen the friction torque. Measure the clock taken for the mass to fall through Im then a=2s * m then ?= a (rad/sec^2) t^2 s^2 R Also P=m*g-m*a=m[9.81-a] Nt And for the calculation of scam of inertia of the system referred to shaft1 we engagement: Ieqv= I1+I2*[Na] ^2+I3 [Na*Nc] ^2 Nb Nb Nd Procedure: 1.         Determine, by the dropping weight method the moments of inertia associated with each of the single shafts. 2.         Assemble the system so that the gears meshed. 3.         Determine by the falling weight method the equivalent inertia of the system at the fist shaft. 4.         Compare the equivalent inertia with the theoretical organic evolution the equation: Sample Calculations: M=F = 1=0.101 Kg g 9.81 a=2s= 2*1 =0.0154 m/sec^2 t^2 11.38^2 P=m(9,81-a)=0.

101*(9.81-0.0154)=0.999 Nt P*R1= 0.999*0.019=0.0190 Nt*m ?= a = 0.0154 =0.8105 rad/sec^2 R 0.019 Table of results: Shaft 1 R=0.031 m S=1 m W(Nt)         t(sec)         a(m/sec^2)         P(Nt)         Pr(N*m)         ?(rad/sec^2) 1         11.17         0.016         0.999         0.031         0.517 2         6.99         0.041         1.993         0.062         1.322 3         4.51         0.098         2.972 ...
