УСТАНОВКА ФОРМОВАНИЯ ДРЕВЕСНО-БЕТОННЫХ ПЛИТ

Abstract

The article presents an approach to the creation of complex mechanical systems, consisting in a combination of automated design systems of various types. This allows not only implementing multivariate design using CAD-systems, but also achieving optimal design solutions for several criteria simultaneously using CAE-systems. Thus, a multi-criteria design problem can be solved. The article presents new design solutions aimed at improving the performance of the installation for the molding of wood-concrete plates. Calculations are made and the designs are presented: rotary wheel racks, which provide movement of the unit in two mutually perpendicular directions; dosing hopper,a conveyor that dispenses and discharges the finished mortar into the formwork using two pneumatic cylinders; plate forming installation frames; batch hopper frames; conveyor frame.The results of the engineering analysis of the frames for the installation of plate molding, metering hopper and conveyor are presented.Engineering analysis was carried out in the ANSYS CAE system. Engineering analysis included five types of calculations: the calculation of stiffness with the conditions of rigid and elastic fastening; modal; dynamic; thermal and thermal-deformational. The analysis of the obtained calculation results allowed making a conclusion about the insignificance of static and dynamic deformation of the frames. The assessment of the thermal deformation state of the elements of the carrier system of the installation for molding wood-concrete plates showed that the magnitude of the temperature displacements is comparable to the dynamic ones.
