Abstract
Problem Statement (Relevance). Ball joints of a car suspension and steering are critical units, since the loss of their operability entails accidents with a threat to the safety of the user. In this regard, the ball joints of the car suspension and steering shall comply with a set of technical requirements provided by various regulatory documents. In Russia, the requirements for ball joints of a car are set forth by GOST R 52433 and Technical Regulations of the Customs Union TR CU 018/2011. It should be noted that these standards are the most general documents, where the requirements for strength, functionality and operational reliability are not fully reflected. Guided by these standards only, there is a high probability of missing important parameters in the design of parts or assemblies, which may lead to a full or partial loss of a normal operation of products. At the same time, OEM customers have additional requirements for the finished product. One of these requirements is starting force of plastic deformation during bending of an outer tie rod ball stud of a car. Methods Applied. This paper describes a proposed calculation of the above mentioned parameter by the simulation of static tests using the finite element method. Originality. The analysis of open sources did not reveal any calculation methods for determining starting force of plastic deformation of ball studs during bending. Practical Relevance. The developed finite element model makes it possible to determine starting force of plastic deformation of the ball stud with an acceptable degree of accuracy at the design stage to avoid a large number of physical experiments and increase the quality of the manufactured products.
Keywords
