Active Suspension of Truck Seat

Design of a Low Power Active Truck Cab Suspension

Semi-active control of seat suspension with MR damper

The vibration control of a seat suspension system with magnetorheological (MR) damper is investigated in this study. Firstly, a dynamical model of the seat suspension system with parameter uncertainties (such as mass, stiffness, damping) and actuator saturation is established. Secondly, based on Lyapunov functional theory and considering constraint conditions for damping force, the semi-active ...

Objectifying Discomfort Seat Measurement for next Generation Truck Driver’s Seat

Comfort is an attribute that today’s drivers demand more and more. Seat is one of the important features of vehicle and there is the place where the professional driver spends most of their time. According to ‘European Union Legislation for Drivers and Promote’, the weekly driving time for truck drivers shall not exceed 56 hours. Assuming eight week vacation and one more for holiday, the truck ...

Active Vibration Control of Passenger Seat with HFPIDCR Controlled Suspension Alternatives

Abstract—In this paper, passenger ride comfort issues are studied taking active quarter car model with three degrees of freedom. A hybrid fuzzy – PID controller with coupled rules (HFPIDCR) is designed for vibration control of passenger seat. Three different control strategies are considered. In first case, main suspension is controlled. In second case, passenger seat suspension is controlled. ...

Subjective and Objective Measurements for Comfortable Truck Driver’s Seat

Technology has changed trucks significantly over the years. As a result, consumer expectations, in terms of performance, have risen. In Western society, the comfort of products has developed into an important issue. Truck manufacturers recognize comfort as one of the major selling point, as it is thought to play an important role for buyers as well. In addition, employers are getting interested...
