Hood Design

Objective:-

In this we are going to design hood inner panel.

Introduction:-

Here we are going to study the design of hood panel as per company standards. It is also known as bonet which mainly covers the engine compartment.

Pedestrian Vehicle Collision:-

Promoting and creating proper facilities for nonmotorized (pedestrian and bicycle) trips is very important in an urban transportation system to enhance pedestrian safety. Pedestrian–vehicle conflicts on urban roads are increasing, particularly at road crossings, because of the tremendous rate of growth in vehicle traffic in developing countries. Accident statistics clearly indicate the need to improve pedestrian safety and to analyze the pedestrian–vehicle interactions and collisions more deeply. This study analyzed the severity of pedestrian–vehicle conflicts at unprotected midblock crosswalk locations under mixed traffic conditions. The pedestrian–vehicle conflicts were considered on the basis of a pedestrian safety margin, which can be defined as the time difference between the time gap of an approaching vehicle and the pedestrian crossing time. For this purpose, field surveys were conducted at eight unprotected midblock crosswalk locations. Data such as pedestrian demographics and behavioral, traffic, vehicle, and roadway characteristics were considered to analyze the severity of the pedestrian–vehicle conflicts. The study identified the significant contributing factors in such conflicts by using an ordered probit model. The model’s results show that rolling behavior, pedestrian speed change condition, land use type, and vehicle speed have a significant effect on the severity of pedestrian–vehicle conflicts. The findings of this study contribute to developing traffic countermeasures to reduce the severity of pedestrian–vehicle conflict levels in order to improve pedestrian safety at unprotected midblock crosswalk locations under mixed traffic conditions. More studies at various unprotected midblock crosswalk locations would be useful to develop guidelines for redesigning the existing midblock crosswalk facilities by introducing suitable traffic control measures.

Car Hood Outer Panel

Mastic sealant is used between inner & outer panel of the hood to reduce vibration and noise and it is a gel like substance which solidifies when heated.

Latches are added where weight is added. On the inner panel we have hinges and strikers.

Emboss are provided in the inner panel of the car hood assembly which helps in weight reduction of the hood and it also dissipates the force during collision.

Deep Drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. Its is therefore a shape transformation process with material retention. This manufacturing process is used extensively in the forming of sheet metal into a cup or box like structures such as cooking pans, containers, sinks, automobile parts mainly panels & gas tanks. A deep drawing of sheet metal is performed with a punch & die. The punch is the desired shape of the base of the part. The cavity matches the punch and is a little wider to allow for its passage as well as clearance.

Final Hood Assembly :-

Conclusion:- After going through skill lync tutorial lectures and through Youtube reference I was able to do the assembly.
