During measurements, the crankshafts of marine engines are usually supported on a set rigid prisms. Such prisms maintain constant height position, cause different values reaction forces and, consequently, may elastic deformations crankshafts. Thus, measurements dimensions and geometry crankshaft be distorted. This article proposes measuring system developed to support with flexible supports. Th...

Abstract One of the characteristic features piston engines are vibrations caused by pistons moving in cylinders. During engine design process, it is necessary to determine level vibration that can occur engine. This especially important for aircraft engines. Due minimization weight aircraft, limit factors may cause damage structure. these vibration, which resonance and, consequently, a dangerou...
