A study of the cultivator suspension’s strength based on its solid model in Autodesk Inventor Professional

Abstract The article is devoted to the study of the stress-strain state cultivator suspension in the Autodesk Inventor Professional program. To solve this problem, a solid-state suspension model has been developed. Four schemes of the application of external forces and restrictions on the suspension parts movement are described, which describe the condition of the cultivator in critical situations - the suspension’s paw clings to an obstacle. The calculations were performed in the “stress analysis” environment. The obtained results made it possible to justify the possibility using two of the four considered schemes to formulate a plan for a comprehensive study of the cultivator’s health when various changes are made to its design. The ultimate goal of design changes is to reduce metal consumption and the use of more affordable materials in the manufacture of the cultivator frame.
