Effect of body effect of body tilt angle to the shaking forces

Abstract

In this paper, a programming of dynamic system calculation is developed to determine the body tilt angle in relation to minimize the shaking forces on the diesel engine’s crankshaft. In this study, 1-cylinder diesel engine is taken as an example. Position, velocity, and acceleration of pins of the engine mechanism determined by using vector analysis. Masses and mass moments of inertia of the linkage are used to generate the forces and moments. Cartesian coordinate principle is used to form linear equations. These equations are solved by using gauss elimination method to obtain the shaking forces on the crankshaft. Calculation result is validated by comparing it to the polygon method and Newton principles. Based on the graphs, the optimum tilt angle of the engine’s body had been B = 87.72 obtained at for minimum horizontal shaking force Rx = 2.07 Newton.
