Genetic Algorithm Optimization of a Six Degree of Freedom Micro Parallel Robot

Pareto Optimization of a Two-degree of Freedom Passive Linear Suspension Using a New Multi-objective Genetic Algorithm (TECHNICAL NOTE)

The primary function of a suspension system of a vehicle is to isolate the road excitations experienced by the tires from being transmitted to the passengers. In this paper, we formulate an optimal vehicle suspension design problem with the quarter-car vehicle dynamic model. A new multi-objective genetic algorithm is used for Pareto optimization of a two-degree of freedom vehicle vibration mode...

Silicon Piezoresistive Six-Degree of Freedom Micro Force-Moment Sensor

In this paper, we describe the design, fabrication and calibration results of a 6-degree of freedom force-moment micro sensing chip utilizing the piezoresistance effect in silicon. The sensing chip is designed to be able to simultaneously detect three components of force and three components of moment in three orthogonal directions. Conventional p-type and four-terminal p-type piezoresistors ha...

Double Circular-triangular Six-degrees-of-freedom Parallel Robot

This paper describes a new structure of a six-DOF parallel robot. First, a known planar three-DOF double-triangular structure is modified by replacing the stationary triangle with a circle. It increases the work envelope considerably especially when rotational motions are required. The ability for unlimited rotational motion allows extending the structure into six-DOF by using two sets of stati...

Discrete Direct Sensititivity Analysis Method of Bending Element with Six Degree of Freedom

This paper is about discrete sensitivity analysis. A triangular bending element with constant moment and six degrees of freedom is used. The required derivatives for sensitivity analysis are calculated explicitly. These formulations, finite element method and sequential linear programming are utilized to find shape optimization of plate bending structures. The numerical examples, which show the...
