Design Optimization of Bullock Cart Yoke

Abstract

Abstract Since from ancient times weight of bullock cart is concentrated on the neck of the bullock reducing its efficiency. This paper presents various design of the yoke structure for the cart and its analysis whose aim is to reduce the stress acting on the single point i.e. on the neck of the bullock. The stress needs to be distributed over the entire body of the bullock instead of concentrating only on the neck. This paper gives an idea of how the stress is distributed on the bullock and the deflection of the yoke corresponding to the load. The design iterative process is based on the presently used bullock cart yoke structure. This paper also includes the design concepts which provide cushioning at the contact of the wooden frame to the bullock. The best design is then selected based on the structural behaviour for particular boundary and loading conditions. The modelling is done in SOLIDWORKS 2017 software and simulated/analysed using ANSYS 18.2 software.
