Advanced CAE simulation with finite element method was used as a tool for this research. Main aim of this article is to show procedure how to determine optimal level of injection pressure, packing pressure and times of all injection phases. All these parameters lead to improving of final properties of product. Wide range of values is given for each parameter and it is necessary to determine the suitable value. Exact influences of each parameter on the final product were detected with usage of CAE simulations of injection molding. All these dependencies were in article described. Research was focused on influence of all parameters on final product and also on technological process. Level of mold filling, number and size of weld lines, number of air traps and overall production times were chosen as main parameters for evaluation. Reference part is reinforcement profile from spoiler in racing formula car. Process with mean values of each parameter was chosen as a reference process. Influence were tested on product from high density polyethylene. Material properties for CAE simulation were clearly described in this article. All simulations were validated by experiment performed on real injection molding machine.","PeriodicalId":356055,"journal":{"name":"2017 International Conference on Mechanical, System and Control Engineering (ICMSC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130659528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A modified proportional-integral-derivative (PID) based on observer method is used as a controller. Uncertainty is considered on thruster model, thrust level, and external disturbance parameters. Thruster is modeled with a constant delay followed by a second-order binomial transfer function. The modulator update frequency, the input to the on- off thruster, is limited to 50 Hz. Controller gains are tuned and optimized using a multi-objective genetic algorithm. The simulation results of the deterministic optimization show that the rise time is reduced and the overshoot is removed. Moreover, robust optimization is applied to this problem using a combination of deterministic optimization and Monte Carlo simulation. Next, the statistical properties of the results, such as expected value and variance are evaluated. These properties are used as the objective functions of the optimization problem, and the results are compared to each other. The variation of objective function in robust optimization is reduced, which means that the robustness under uncertainties is enhanced. Using quasi-normalized equations and merging the moment of inertia, thrust level and filter gain with other parameters, the results are more general and useful for other spacecraft with different characteristics.","PeriodicalId":356055,"journal":{"name":"2017 International Conference on Mechanical, System and Control Engineering (ICMSC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126459403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An airbox designed for a light single-seat racing car was chosen as a representative example. The numerical analysis is primarily focused on the maximum reduction of the mass of the component while retaining adequate stiffness and strength and also taking into account the manufacturing technology of the component. Carbon composite fabrics in combination with high performance epoxy resin were used to ensure the maximum stiifness of the part. In order to ünd the best option, an advanced CAE simulation based on the Finite Element Method was used with a special module designated directly for creating models from alternative materials. Zone-based and ply-based FE models were created to find the optimal layout of the individual plies of the laminate. Maximum stress failure criterion was used to evaluate the strength of the part. A 3D model for the numerical simulation follows all the layers of the composite materials, including cuts, notches, resin drops and precise calculation of the main directions of the fibres and their distortion or overlap caused by more complex shaped surfaces.","PeriodicalId":356055,"journal":{"name":"2017 International Conference on Mechanical, System and Control Engineering (ICMSC)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132369017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
