The paper establishes the mathematical model of the double wishbone independent suspension, analyses the specific structure in theory, uses the softwares of ADAMS and MATLAB to simulate the functions which arenearly similar with the actual working conditions.
On the conditions of known probabilistic characteristics of basic random variables,the reliability design parameters of automobile semiaxle flanges can be obtained simply and accurately by using perturbation method to carry out the design and compile practical computer program.
The performance of the compressor for automobile air conditioning under changing conditions is analyzed, and the designs of the automobile air conditioning condenser under different working conditions are discussed. By analyzing the effect of the changes in condenser temperature and increase of temperature of cooling medium on the design of the condenser, reasonable design parameters of the condenser are obtained. Finally the matching design of the condenser, compressor and whole system is achieved.
Based on the mathemtical model of CVT power transmission established by Shinya Kuwabara and Tom Fuji,the force conditions of CVT components are analyzed and the relations of each component of force are given.
Adopting the stochastic perturbation method and particle swarm algorithm to carry out reliability steady optimal design,utilizing the fuzzy multi-objective particle swarm optimization method to find out all pareto solution sets that satisfy the constraint conditions,by combining with the practical situation and in accordance with pareto solution sets to determine the specifications of parts and components.
The new Lexus 400 cars use the intelligent and electronic - controlled throttle control system (ETCS - i), the engine ECU can calculate the throttle opening according to accelerating pedal position and the different driving conditions.
This paper creates an optical design mathematical model of Gawood elevating mechanism of mototilters, and also gives its objective function of optical design: min(KO)=min[(XG ·DAEC )/(DOEC ·DAEB )], and its evaluation index: α=Pmax / P-1 , meanwhile the paper introduces a method to find constraint conditions and some notices of this optical design mathematical model, therefore it can provide a set of methods for designing mototilters.
As a consequence, the action is linearizable if certain topological conditions are satisfied.
An algebraicG-varietyX is called "wonderful", if the following conditions are satisfied:X is (connected) smooth and complete;X containsr irreducible smoothG-invariant divisors having a non void transversal intersection;G has 2r orbits inX.
Here we provide certain conditions (more general than those in [Ka1]) which guarantee preservation of the topology under a modification.
We express the vanishing conditions satisfied by the correlation functions of Drinfeld currents of quantum affine algebras, imposed by the quantum Serre relations.
We discuss the relation of these vanishing conditions with a shuffle algebra description of the algebra of Drinfeld currents.
