| The lightweight of the car is reduce the weight of the vehicle as much as possible on the basis of ensuring the strength and safety of the car is not reduced, so as to improve the power utilization rate, reduce fuel consumption, and reduce the exhaust pollution.This paper, as a Jiefang 8×4 dump truck chassis as the research object,combined with the actual production situation of the company, a series of measures to reduce the weight of the original chassis is adopted,finally reached the goal of reducing weight,and has put the product into the market in small quantities. According to the actual use of tracking users,can be concluded that the effect of lightweight is good,product performance has a certain increase in the conclusion.In the process of reducing weight analysis, this paper focuses on the optimization of the frame and rear suspension,the optimization of the two total weight is the use of Pro/E for three-dimensional modeling,the use of Msc.Patran for three-dimensional model of the grid processing,the use of Msc.Nastran analysis. |
