Scientific Contribution

The following contributions and studies are some of Professor Jazar’s innovative and new applied methods that are currently academic or industry standard.

  • Razi Acceleration and Correction of Coriolis Acceleration. I have developed the theory of derivative in relatively moving frames. The theory has shown a new acceleration term (Razi acceleration) and splitting the coriolis acceleration in two different terms when there are three coordinate frames are involved.
  • Theory of Order Free Transformations. I have developed the order free transformation theory. It redefines the transformation matrices of connected multibodies such that the order of matrix multiplication in kinematic analysis of the system is immaterial. Therefore, the actuators in a manipulator are free to be actuated in any arbitrary order.
  • Autodriver Algorithm. I have presented a method for smart autonomous vehicles to eliminate the need of steering by drivers in well-defined roads. Employing the GPS and using four-wheel-steering system we may eliminate steering by driver and keep the vehicle on the road during long-range travels.
  • Caster Theory in design of Smart Vehicles. Introducing the screw theory, I have presented the required equations to calculate the camber angle based on caster and lean angles of a steerable wheel as a function of steer angle. So, we are able to design a smart vehicle to control the lateral force by varying the caster angle, independent of the input steer angle by the driver. The method can be used to increase safety of street cars, and maximize the cornering response of sport cars.
  • Mathematical Modeling of Squeeze-Film and Thermal Damping in MEMS. I am one of the first investigators who could introduce the mathematical model of the thermal effects and squeeze-film effects in micro-resonators. Employing the Lorentzian function, I modeled the thermal effects as Temperature Relaxation, and Thermal Damping. The model of squeeze-film effects are presented by a Fifth Degree Stiffness and Third Degree Damping.
  • Development of RMS Optimization Method. I (with contribution of Prof. Golnaraghi, U. Simon Fraser, Canada) have introduced the RMS Optimization method to optimize the behavior of vibration isolators. The RMS Optimization method is based on minimization of the Root Mean Square (RMS) of absolute acceleration versus RMS of relative displacement.
  • Mathematical Model of Hydraulic Mounts. Although the hydraulic engine mounts have been introduced as an effective vibration isolator since 1980, their behavior has not been described mathematically before 2001 when I (with contribution of Prof. Golnaraghi, U. Simon Fraser, Canada) provided an applied mathematical model to describe the nonlinear behavior of the decoupler. Employing the model, we successfully determined the frequency response of HEMs.
  • Piecewise Functional Vibration Isolator. I (and Prof. Golnaraghi, U. Simon Fraser, Canada) are the first who could derive a mathematical model to describe the frequency response of piecewise linear vibration isolators, using a modified averaging method. The model uncovered several hidden and confusing behavior of piecewise functional systems, such as jump avoidance condition and frequency island.
  • Dynamic Systems with Saturating Elements. To model the new industrial vibration devices such as magneto rheological dampers, I introduced an efficient mathematical model to describe the frequency response of systems with saturating elements.
  • Floating-Time Method. I have introduced, developed, and applied Floating-Time method to solve minimum-time-control problems of nonlinear and multiple degrees-of-freedom dynamic systems subject to bounded inputs. This method has been added to the arsenal of existing approximate and numerical methods that have been developed over the last fifty years for optimization based control and open control platforms. A novel feature of the Floating-Time method is that it supports any constraints on dynamical states, including space, velocity, acceleration, and jerk limitations.
  • Energy-Rate Method. I have introduced and applied an effective method known as the Energy-Rate method to develop the stability map of parametric systems.
