Piezoresistive Pressure Sensor

The relative research of low range and high anti-overload piezoresistive pressure sensor is carried out in this paper and a new kind of sensor chip structure, the double ends-four beam structure, is proposed. Trough the analysis, the sensor chip structure designed in this paper has high sensitivity and linearity. The chip structure is specially suit for the micro-pressure sensor. The theoretical analysis and finite element analysis is taken in this paper, which provide important scientific basis for the pressure sensor development.

Visual inspections of selected semitrailers during routine equipment checks revealed that the kingpin bent in the direction of 180 degrees from the direction that the semitrailer is towed. Confirmation from semitrailer repair facilities found that in some cases the semitrailer’s supporting structure developed unexpected cracks. These cracks were not thought to be age related but were most likely caused by high stresses from unknown high loads. In an effort to determine the forces at the kingpin and fifthwheel, TruckSim® modeling and simulation software was utilized to predict the forces in all three directions during various operating maneuvers. Computer simulations suggest the largest forces are experienced during coupling operations as opposed to severe maneuvering or braking. The development of a Finite Element Analysis (FEA) model of the tractor-semitrailer coupling determined that high coupling speeds would overload the kingpin-fifthwheel structure. The FEA model also allowed researchers to determine that a damping system would lower the forces at the kingpin-fifthwheel interface to the magnitude of forces experienced during normal operations. A literature search found no valid documented tests, and determined the SAE J133 kingpin loading requirements were incorrect.

Stiffness Model

It is designed a Fast Tool Servo (FTS) device which based on piezoelectric ceramic and jointed by flexible hinge. The flexible hinge has been analyzed and optimized both by the theoretical calculation and finite element analysis; and it has been physically manufactured and tested by means of pressure sensor and laser interferometer. The stiffness model was established. The driving voltage and displacement relationship has been revealed. The results indicate that this FTS system can reach a travel range for 60μm,the frequency response precedes 150Hz within 39μm travel range.
