Abstract
The article discusses a rotory-vane heat engine with a lever-cam mechanism motion conversion (an engine may be an internal combustion or external combustion). The output shaft of the engine adds drive torque from the working fluid pressure forces acting on the blade and the inertial moment of the forces of inertia of engine components. The mechanical strength of the motor is dependent on the magnitude and phase of these two torque. The purpose of the article is to determine the conditions under which mechanical strength is minimized.
Highlights
It is known that internal combustion engines have almost reached the limit of their energy and environmental characteristics
In this article, we have obtained the analytical expressions for motor driving and inertial moments of the single-module rotary-vane engine with lever-cam referenced to the output shaft, the condition under which the forces of inertia completely compensate the most significant component of the disturbing drive torque and minimizes the mechanical strength of the engine
The results of numerical simulation obtained on the example of the engine with internal combustion, which are close to the theoretical prediction
Summary
It is known that internal combustion engines have almost reached the limit of their energy and environmental characteristics. It is necessary to develop engines of a new generation, constructed using other design schemes and implementing new thermodynamic cycles. To solve this problem rotor-vane machines with external heat supply can be used. Linear bearing mB mR MB2 Output shaft w M JF Flywheel Cam MB1
