Abstract
Fierce competition in India’s automotive industry has led to constant production innovation among manufactures. This has resulted in the reduction of the life cycle of the design philosophies and design tools. One of the performance factors that have continues to challenge automotive designer is to design and fine tune the braking performance with low cost and short life cycle.
Braking performance of automotive vehicle is facilitated by the adhesion between the tyre and the ground. Braking force generated at the wheels of a vehicle have to appropriately match to the adhesion. Antilock braking system (ABS) is used for this purpose. ABS is a modern braking system which could significantly improve directional stability and reduce stopping distance of a vehicle. However this system still too complicated and expensive to use in low end compact car and pickup truck.
In this research, the adaptation of a load sensing valve on the subject vehicle along with the real time performance is evaluated and compared with the simulation results using MSC.ADAMS/CAR software.
Close correlation is established between actual testing and the simulation. The results show that load sensing valve actuation with respect to spring deformation could control the fluid pressure in order to reach equal time lock between front and rear wheels. A combination of load sensing valve and spring system could develop significant effect of ABS which is simple and economic enough to use low end car and pickup truck.
