ZRJX-FLD-2 mechanical dynamics flywheel speed control experimental bench The
experimental bench adopts The most typical small punch structure with flywheel speed regulation in engineering applications was used as the experimental object, and innovative designs were made on its components. It was designed into an innovative combination test bench with adjustable punching force, flywheel inertia, and convertible working resistance mode of the unit, making the experiment The test object can be transformed according to the working resistance mode. By replacing a few simple parts on the experimental bench, the mechanical structure of the experimental bench can be changed. The experimental bench is converted from a punch structure bench to a press structure bench. The working resistance form is changed from the impact force mode to the crankshaft angle in a random group. Linear changing pressure change mode, and can change the impact force or pressure change value. Analyze and study the dynamics of mechanical systems by measuring the smooth motion patterns and starting and braking characteristics of flywheels in different working resistance modes.
