Toughness research of construction elements of functional-transporting mobile devices

Abstract

There is made an analysis of constructive peculiarities of technological machines in current work. This machines have such a function as water or work liquids transporting. The problem which often happens with those transport devices is tank mechanical destruction. It is choosen one of machine groups which transports cylinder tanks in conducted research. The peculiarity of presented tanks construction is their leaning on supports, which look like beddings, and fixed with flexible bandages. We have to analyze the tense deformation state to find a reason of current constructions destruction. We can make calculations if loading on side wall of tank (cylinder part of tank) is known. According to literature sources analysis the loading on cylinder side wall of tank can be divided by several components: liquid pressure on tank sides, can be added redundant pressure; from support interaction (contact pressure); and from tightens of bandages. Task determination of tense deformation state is rather difficult and its solution should be step by step. That's why, in current work, mathematical models of loading of bandages tightening while tank fixing to supports are shown as a local task for loading determination at all. The procedure of function transforming to trigonometric series conducts after receiving end equations of contact pressure of bandages on cylinder side wall of tank and equations of other loading components. Then held equations integrate to general calculation model for determination of tense deformation state of cylinder side wall of tank of technological machine. In the end result it will allow us to choose speed mode of liquids transporting considering the process dynamics.
