Material Selection in Structuring of Car (BIW) body

Image
We have discussed about the crumble zone of the vehicle is our last article.structuring of press parts is essential to provide the strength of crumble zone. Material selection is important aspect in automobile sector, which is proportionally impact the safety, Milage,Weight & Cost of the car. In cars basically Impact beam, A-pillar, B-pillar, D-Pillar & Sill-Inner are play important role in  Strengthening & structuring. All the above discussed Zone are provided or made up of High strength steels like B-pillar & D-piilar is made up of E32 graded material, A-pillars & Sill-inner are made up of like HSLA, IFHS, D513 etc Material. Material usage is depends on the cost of the vehicle which companies are gong to decide at what budget they are launching the vehicle in market. Now are days there are many car companies are using the low grade material to get cost reduction, which is directly impacting the safety of costumer. As we all know the vehicles of Ma...

LSPV- Load Sensing proportioning valve.

Load sensing proportioning valves are use in passenger vehicles & in commercial vehicles too. it is found very much effective in commercial vehicles because the vehicles will carry the more load. As we know all during the travelling or motion of vehicle, parts or the things associated with body also in motion. which will cause the balancing of the vehicles some time. such kind of balancing are taken care by many more technologies like ABS, EBS etc. In basic functioning of brakes hydraulic lines are connected to each of the wheel of vehicles, the brake fluid plays important role in controlling the motion of vehicle. for loaded vehicles more compressed brake fluid required. where as for lighter vehicle not much fluid pressure is required.  The system includes a load sensor oriented between a suspension component, such as a supporting spring, and the vehicle frame or body and includes a cavity for in compressible fluid in which variation in load will vary the volume o...

Vehicle Structuring

Image
This is common assumption that lightweight cars are unsafe. this assumption is completely wrong.safety is not dependent on the weight of the vehicle but dependent on the crumble zone of the structure. TATA NANO is one of the lightest vehicle(Around 600kg), but not a single report is reported for wind blowing & off road due to lighter weight.  Now are days manufactures looking for lighter weight vehicles for good consumption of fuel and greater mileage. Lighter vehicles have better power to weight ratio. manufactures are working to to have a lighter vehicle with lot of light weighted materials.  As we are talking about the crumble zone, vehicle are made enough to take the impact of the obstacles. it it heavily dependent on the structuring of the sheet metal. and also designed aerodynamically.
