| 1 | Lightweight Design of Commercial Vehicle Cab Based on Fatigue Durability显示文摘To better improve the lightweight and fatigue durability performance of the tractor cab,a multi-objective lightweight design of the cab was carried out in this study.First,the finite element model of the cab with counterweight loading was established and then confirmed by the physical testing,and use the inertial reliefmethod to obtain stress distribution under unit load.The cab-frame rigid-flexible couplingmulti-body dynamicsmodelwas built by Adams/car software.Taking the cab airbag mount displacement and acceleration signals acquired on the proving ground as the desired signals and obtaining the fatigue analysis load spectrum through Femfat-Lab virtual iteration.The fatigue simulation analysis is performed in nCode based on the Miner linear fatigue cumulative damage theory.Then,with themass and fatigue damage values as the optimization objectives,the bending-torsional stiffness and first-order bending-torsional mode as constraints,the thickness variables are screed based on the sensitivity analysis.The experimental design was carried out using the Optimal Latin hypercube method,and the multi-objective optimal design of the cab was carried out using theKriging approximationmodel fitting and particle swarmalgorithm.The weight of the optimized cab is reduced by 7.8%on the basis of meeting the fatigue durability performance.Finally,a seven-axis road simulation test rig was designed to verify its fatigue durability.The results show the optimized cab can consider both lightweight and durability. | Donghai Li Jiawei Tian Shengwen Shi Shanchao Wang Jucai Deng Shuilong He | 2023 | Computer Modeling in Engineering & Sciences2023，，7： | 2 |
| 2 | Optimization of Engine Control Strategies for Low Fuel Consumption in Heavy-Duty Commercial Vehicles显示文摘The reduction of fuel consumption in engines is always considered of vital importance.Along these lines,in this work,this goal was attained by optimizing the heavy-duty commercial vehicle engine control strategy.More specifically,at first,a general first principles model for heavy-duty commercial vehicles and a transient fuel consumptionmodel for heavy-duty commercial vehicles were developed and the parameters were adjusted to fit the empirical data.The accuracy of the proposed modelwas demonstrated fromthe stage and the final results.Next,the control optimization problem resulting in low fuel consumption in heavy commercial vehicles was described,with minimal fuel usage as the optimization goal and throttle opening as the control variable.Then,a time-continuous engine management approach was assessed.Next,the factors that influence low fuel consumption in heavy-duty commercial vehicles were systematically examined.To reduce the computing complexity,the control strategies related to the time constraints of the engine were parametrized using three different methods.The most effective solution was obtained by applying a global optimization strategy because the constrained optimization problem was nonlinear.Finally,the effectiveness of the low-fuel consumption engine control strategy was demonstrated by comparing the simulated and field test results. | Shuilong He Yang Liu Shanchao Wang Liangying Hu Fei Xiao Chao Li | 2023 | Computer Modeling in Engineering & Sciences2023，137，12： | 0 |
| 3 | Maximal-overlap adaptive multiwavelet for detecting transient vibration responses from dynastic signal of rotating machineries显示文摘Vibration signal is an important prerequisite for mechanical fault detection.However,early stage defect of rotating machineries is difficult to identify because their incipient energy is interfered with background noises.Multiwavelet is a powerful tool used to conduct non-stationary fault feature extraction.However,the existing predetermined multiwavelet bases are independent of the dynamic response signals.In this paper,a constructing technique of vibration data-driven maximal-overlap adaptive multiwavelet(MOAMW)is proposed for enhancing the extracting performance of fault symptom.It is able to derive an optimal multiwavelet basis that best matches the critical non-stationary and transient fault signatures via genetic algorithm.In this technique,two-scale similarity transform(TST)and symmetric lifting(SymLift)scheme are combined to gain high designing freedom for matching the critical faulty vibration contents in vibration signals based on the maximal fitness objective.TST and SymLift can add modifications to the initial multiwavelet by changing the approximation order and vanishing moment of multiwavelet,respectively.Moreover,the beneficial feature of the MOAWM lies in that the maximal-overlap filterbank structure can enhance the periodic and transient characteristics of the sensor signals and preserve the time and frequency analyzing resolution during the decomposition process.The effectiveness of the proposed technique is validated via a numerical simulation as well as a rolling element bearing with an outer race scrape and a gearbox with rub fault. | HE ShuiLong ZI YanYang ZHAO ChenLu CHEN BinQiang WANG XiaoDong HE ZhengJia | 2014 | Science China(Technological Sciences)2014，57，1： | 0 |
