Structural Analysis

Mechanical elements used in real life tend to show non-linear behaviour for reasons of material conditions, fasteners, assembly errors, applied loads, etc. As Simunes, we perform structural analysis activities of mechanical parts. Thus, before the parts are produced, the relevant analyses are performed, the errors in the parts are detected and the 3D geometry is adjusted. Using the finite element analysis method, possible deformations and stress values are determined based on dynamic and static loads. Thus, constraints on the previously determined geometric design are determined and parts are optimized.

Buckling Analysis

Generally, buckling condition is observed in structures with thin and long geometries. For structures that may be critical in terms of buckling, not only static analysis should be performed, but also whether the structure is safe from buckling should be confirmed by buckling analyses. Damage to structures can be caused by buckling and plastic deformation. Euler calculation method gives fairly good results in case of damage only due to buckling below the yield strength of the structure. In some cases, buckling and plastic deformation can be Decoupled together. In such cases, it is necessary to perform non-linear analyses to be able to more accurately model the behaviour of the structure.

Modal Analysis

In modal analysis, it is aimed to calculate the dynamic stability of the systems by reaching the natural operating frequency values of the structure. To avoid resonance, the natural frequencies of the systems must be obtained.

Vibration Analysis

Vibration is the reactive behaviour of a machine element against internal and external forces in a mechanical component. Vibration signals produce a complex waveform due to the action of different forces. As Simunes, we perform deformation and strength analyses based on frequency and amplitude parameters during vibration analysis, which are affected by non-linear loads. We use a random vibration study to calculate the response caused by non-linear loads.
The following cases can be given as examples of non-linear loads:
-Loads on the wheel of a car travelling on a rough road
-Main accelerations caused by earthquakes
-Pressure generated by air turbulence
-Sea waves or strong wind pressure

Fatigue Analysis

Fatigue analysis allows designers to estimate the fatigue life of products, such as auto-mobiles, airplanes, heavy equipment, electric motors, and electronic components. The analysis obtains data on crack growth and strength, which we can use to make informed choices to ensure product integrity and optimize fatigue life, thus preventing untimely product damage of the part during the use phase. We can apply fatigue analysis to determine why an existing product failed, so that we can safely redesign your product and prevent unexpected damage. In this analysis, it is aimed to calculate the life cycle of the design. Firstly, the stress and strain values on the structure were studied. Secondly, the fatigue life was simulated on the basis of S-N and ε-N.

Ballistic Analysis

7.62x51mm / 308 AP Ballistic Bullet Analysis. The effects of the projectile on the armour are simulated. The 7.62x51mm NATO/308 caliber projectile was fired at RHA armour.

Hand Grenade Explosion Analysis

Hand grenade is one of the most used grenades for attack and defence. In this analysis, it is aimed to simulate the effects of grenade explosion on 10 mm thick armour.

HEAT Shell / Shaped Charge

High Explosive Anti Tank (HEAT) shell is a type of shaped explosive that uses the Munroe effect to penetrate thick tank armour. HEAT is a type of chemical energy (CE) ammunition used against modern vehicle armour. The warhead functions by having the explosive charge collapse a metal liner inside the warhead into a high-speed superplastic jet. This superplastic jet can pierce armour steel to a depth of seven or more times the diameter of the charge, but it is often used to immobilize or destroy tanks. In this analysis, two different types of HEAT projectile ammunition, designed with a nozzle angle of 90 and 118 degrees, were analysed to pierce the same 300 mm thick RHA (Rolled Homogeneous Armour).

155mm M107 High-Explosive Artillery Ammunition

High Explosive projectile is a type of chemical energy (CE) explosive and penetrating ammunition used effectively against infantry and modern light armoured vehicles. In this analysis, 6.5 kg of TNT was detonated in the 155mm M107 ammunition. The 80mm RHA (Rolled Homogeneous Armour) failed to prevent the penetration of the ammunition.

APFSDS Shell

Armour Piercing Fin Stabilized Discarding Sabot (APFSDS), long dart piercing or simply dart ammunition, is a type of kinetic energy (KE) piercing ammunition used to attack modern vehicle armour. As a weapon for main battle tanks, it replaces Armour Piercing Discarding Sabot (APDS) ammunition.

Compozite Analysis

Simunes has extensive capabilities in the analysis of strength and damage behaviour of composite materials under various loads and environmental conditions. Loading conditions include biaxial, multiaxial loads and heat transfer scenarios. Composite aircraft parts and automotive chassis parts can be given as prime examples among the projects we have worked on in the field of composite materials.

Mechanism Analysis

As Simunes, we analyse the kinematic parameters of mechanisms such as position, displacement, velocity and acceleration in a virtual environment. We examine the current movements of the mechanism under defined boundary conditions and obtain kinematic results.

Milling Manufacturing Analysis

Milling is the most widely used cutting method in manufacturing and CAM applications. In this analysis, the cutting tool is analysed. Cutting tools operate under high impact loads, and it must be ensured that cutting tools do not break under guaranteed impact loads.

Forging Analysis

The purpose of this analysis is to give shape this metal according to the shape of the mold. The reaction force of how many Newtons is needed to forge this plate should be obtained. The Non-linear Adaptivity Region is used and adjusted to be able to analyse these geometries in the structural module.

Thermal Analysis

In order to investigate and solve the problems caused by heat, we carry out activities on detailed thermal analysis services. We support the development of products by understanding the thermal properties and actions of liquids, gases and their contributions to the effects caused by convection, conduction and radiation, and by innovative design verification processes.

Internal Flow Analysis

In this study, the flow analysis that will occur in the manifold block is simulated. The flow that will occur by obtaining the optimum manifold design is realized as laminar as possible, and the thermal effect of the discharged burned air-fuel mixture to be on the manifold block is calculated.

External Flow Analysis

External flow analysis was performed on the aircraft wing structure. Wind speed, turbulence and vibration values in the wing connection zones that will occur on the aerodynamic profile with the effect of wind load were calculated.

Elektronik Cooling Analysis

Electronic cooling analysis were applied on geometries. In this analysis, revisions were applied to the position of the fan structure on the system and the design of the heat-sink in order to minimize the temperature of components to increase the operating stability of the system and effectively increase heat transfer.
