Heat Ingress Mitigation In Driver Cabin and Driving Comfort Enhancement Using CFD for Off-Road Vehicles

Abstract

The Indian Tipper truck market was 1.65 $ billion in 2020 and it is projected to grow 11% in coming 5 years due to increasing numbers of infrastructure projects and also due to governments new financing policies to support business endeavors and ease of business. Looking to this opportunity every manufacture is eying on market share and by this customer centric market share is always need of hour. As tippers are used for transporting materials and are involved in intense mining & construction operations in off-road which demands good amount of ground clearance due to this all important parts should be above chassis level height like Exhaust system to avoid damages due to off-road conditions, acting to this problem Engineers attempted and succeed to package Exhaust system vertically behind cabin & looking at application requirements also its operational intensity. We faced challenges to maintain balance between Engineering  requirements and customer  comfort, as customer dis-comfort can be of any type related handling ,atmosphere inside cabin etc. while vehicle operating. Above scenario of discomfort was faced by customer i.e. cabin inside temperature increasing due to exhaust system packaging behind driver cabin. This problem was resolved with an Engineering technology to perform analysis of different illustrations on virtual interface i.e. Computational Fluid Dynamics (CFD) analysis. The design with most favorable CFD results further taken for physical validation and the thermal results inside cabin found within acceptable limits.
