Mechanical simulations

With mechanical simulations, the design of the device is analyzed during the initial design stage. The product is evaluated at the sketch stage, so many solutions can be simulated without having to make expensive tools and parts. The mechanical strength of the products is calculated and product optimization is carried out even before the first prototype is made.

After the simulation phase, we possess a prototype that is thoughtfully designed to meet the high demands of customers. This reduces the time and cost needed to produce the finished device.

What do the mechanical simulations give us?

Savings at the product development stage;
Evaluating the design for durability;
Optimization of structure/design;
Determination of forces acting in components;

Visualization of mechanism movement;
Optimization of mechanisms for noise;
Determination of product life cycle.

What do we simulate?

Assembly of the product;
Operation of the hooks;
Mechanical shock;
Random/forced vibration;
Misuse force;

Kinematics of mechanisms;
Free fall;
Wheel overrun;
Crashes, impacts.

Mechanical simulations in our company are divided into 4 main groups:

Statics
Non-linear dynamics
Kinematics
Vibrations

Statics

Statics is the broadest group of mechanical issues that the field of simulation deals with. It refers to phenomena that are slowly changing over time, such as the assembly of equipment or the operation of hooks. Most often, the purpose of this type of research is to predict the behavior of a structure under applied loads based on the distribution of stresses, reaction forces and deformations. Among other things, static simulations form the basis for assessing low-cycle fatigue.

Kinematics

Kinematics is part of the field of mechanics dealing with the geometric aspect of the movement of bodies (mechanisms) without taking into account their mass and the forces acting on them. Unlike in statics, all bodies in the kinematic chain during simulation are rigid bodies and we do not take deformations in them into consideration. In this area, with the help of kinematic simulations, we analyze:

Wheels and gears
Reduction mechanisms (Gearbox)
Shafts and bearings
Mechanical fasteners
Springs
Chains/belts
Cams
Engines
Couplings
Screw-nut gear

Non-linear dynamics

Non-linear dynamics deal with phenomena that vary rapidly over time and these simulations are also performed using the finite element method. The most common dynamic simulations include:

Crash Test
Free Fall
Head Impact
Front/Rear Impact
Over Run

Vibrations

Vibration testing is vital in the product validation process. Vibration simulation deals with phenomena that are repetitive in time, having low amplitudes but operate over many cycles – in the millions. We simulate natural vibration, random vibration and forced vibration in this area. Most often, the purpose of this type of evaluation is to determine natural frequencies and predict potential resonances, structural responses and amplitude magnitudes.

Vibration simulations also form the basis for evaluating high-cycle fatigue.
