Optimization of crank-case shape by using quality engineering and Moving Particle Semi-implicit method

Abstract

Manufacturers must provide products that are robust under use by various types of customers. In this study, the quality engineering was used to optimize the shape of the crank-case considering the influence of the error. The oil behavior in the crank-case was calculated by the MPS method. The optimization was conducted using the orthogonal array L18. The design parameters were related to the shape of the crank-case, and the error was the viscosity of the oil and the revolving speed of the crank-shaft. Furthermore, the crank-case was prototyped and the oil temperature in crank-case was measured to validate the calculation result.
