Lightweight Design of an Outer Tie Rod for an Electrical Vehicle

Abstract

The lightweight design of the outer tie rod installed on an electrical vehicle was achieved through material selection and optimization technique. The aluminum alloy Al6082M was selected as a steel-substitute, and its structural shape was optimized by applying metamodel-based optimization. In this process, finite element analysis was performed to predict the structural responses, such as buckling resistance and fatigue life. First, for an arbitrary base design made of steel, the structural responses were calculated. Then, the design variables were defined to find a lightweight design made of Al6082M. Secondly, metamodel-based optimization based on the kriging interpolation method was applied, leading to determination of an optimum design. The suggested optimum design has the minimum weight satisfying the critical design requirement. Finally, the numerical results of the buckling resistance and fatigue life were validated, through bucking and fatigue tests.

Lightweight Finite Element Analysis and Experimental Study of 90# Fifth Wheel

“…The structure of the fifth wheel mainly consists of the shell, frame plate, support seat, hook lock and slant iron. At the same time the connection parts such as springs and pins in the structure and the parts that have less influence on the force situation of the fifth wheel are deleted in order to simplify the calculation [6,7].…”

Analysis and Optimization of Connecting Tie Rod Assembly in Agriculture Application

“…A four-wheel rumpus crop tractor requires that both front and rear wheels be adjustable squarely, in directive to travel between the plants in the rows [16]. The peak common scheme of varying the width of the wheel tread on ruckus crop tractors currently is to dispose the wheels hubs and tire rims in such routine that by reversing the wheels in relative to the hubs the stamp may be amplified or narrowed [17]. While the development above described may perform to be a artless earnings of amending the stride of the wheels of the tractor, however such amending mechanism fills a long desired want of stingily and easily altering the width of the tread of façade wheels of row crop tractors [18].…”

Outer Tie Rod Design by Using Topology Optimization, Analysis and Verification

“…olarak sıralanabilmektedir [5]. Rot tasarımı ile ilgili yapılan çalışmalarda, çeşitli analiz programları kullanılarak sonlu elemanlar yöntemi ile analiz çalışmalarının gerçekleştirildiği çalışmalar mevcuttur [6][7] [8][9] [10]. Uludamar ve arkadaşları (2018), rot başı şaft bölgesinin karmaşık geometrisi sebebiyle ağ yapısı için parabolik dört yüzlü elemanlar seçerken boru için parabolik prizma elemanlar kullanmış, sonlu elemanlar analizi gerçekleştirmiş ve teorik hesaplamalar referans alınarak analitik ve nümerik sonuçları kıyaslamışlardır.…”
