Experimental approach to modeling of the plasticizing operation in the hot plate welding process

Abstract The paper discusses the topic of butt welding polyurethane drive belts by hot plate method in context modeling process this technological operation. Based on analysis process, a series studies thermomechanical properties material from which belt is made has been planned. results will be used for mathematical and particular its most important phase: plasticizing On basis, study compression cylindrical specimens taken performed at two different speeds. Their result relationship between compressive stress ? c modulus longitudinal elasticity E and: deformation ? , temperature value T as well velocity v . In next step, dynamic viscosity ? was determined based analysis. research work culminated attempts to plasticize plate, conditions similar industrial welding. These were speeds pl resulting correlation force required F speed end relative heated p obtained formulate model material, selected mechanical models.
