ระบบจำลองการทำงานเพื่อทดสอบสมรรถนะ (Simulation Testing)
ระบบจำลองการทำงานเพื่อทดสอบสมรรถนะของ ZwickRoell เป็นโซลูชันสำหรับจำลองแรงและสภาวะการใช้งานจริงของชิ้นส่วนหรือผลิตภัณฑ์ เพื่อประเมินความแข็งแรง ความทนทาน และประสิทธิภาพก่อนนำไปใช้งานจริง โดยสามารถทดสอบแรงดึง แรงกด และแรงบิด (Tensile–Compression–Torsion) รวมถึงแรงที่เกิดขึ้นซ้ำ ๆ หรือสภาวะการใช้งานเฉพาะ
Why Simulation Testing?
- Realistic Performance Evaluation
- Durability Assessment
- Failure Detection
- Product Development
- Performance Validation
Products are often exposed to complex and changing conditions throughout their service life. Simulation testing allows these conditions to be reproduced in a controlled laboratory environment, making it possible to identify potential weaknesses and evaluate performance before the product is used in the field.
From Real-World Use to Laboratory Testing
Real-World Conditions
Identify the forces, movements, cycles, and conditions experienced during actual use.
Test Simulation
Reproduce these conditions in a controlled testing environment.
Measurement & Analysis
Measure force, displacement, deformation, cycles, and other relevant parameters.
Performance Evaluation
Determine whether the product meets its required performance and durability criteria.
What Can Be Simulated?
Mechanical Loads
Products can be subjected to different types of mechanical forces that represent the loads experienced during normal operation.
- Tension – Simulates pulling forces acting on a component.
- Compression – Reproduces forces that push or compress a component.
- Bending – Evaluates how a product responds when subjected to bending forces.
- Torsion – Simulates twisting or rotational forces.
- Combined Loads – Reproduces situations where multiple forces act on a component simultaneously.
Repeated Loading
Many products are not subjected to a single load. Instead, they experience thousands or millions of repeated loading cycles throughout their service life.
Simulation testing can reproduce these repeated loads to evaluate how a product behaves over time.
For example, a component may repeatedly experience:
Load → Release → Load → Release → Load
This allows manufacturers to determine whether the component gradually develops deformation, cracks, wear, or other forms of failure.
Realistic Load Profiles
Actual operating conditions are rarely constant. The force applied to a product can increase, decrease, change direction, or occur at different speeds.
Simulation Testing can reproduce a defined load profile that represents the sequence of forces experienced during actual operation.
For example: Low load → High load → Hold → Release → Reverse load → Repeat
Instead of testing a product with one constant force, the test can reproduce a more realistic sequence of events.
Movement & Displacement
Simulation testing can also reproduce specific movements or changes in position that occur during normal product operation.
This can include:
- Controlled displacement
- Repeated movement
- Extension and retraction
- Rotational movement
- Defined movement sequences
The movement can be controlled according to parameters such as distance, speed, frequency, and number of cycles.
Speed & Strain Rate
The same force can produce very different results depending on how quickly it is applied.
Simulation Testing can therefore reproduce different loading speeds or strain rates to represent different operating scenarios.
For example:
- Slow, controlled loading
- Normal operating speed
- Rapid loading
- High-speed loading
Service-Life Conditions
Simulation testing can combine different loading conditions into a test sequence designed to represent the expected service life of a product.
Rather than simply asking “How much force can this product withstand?”, the test can investigate:
“How will this product perform after being used repeatedly under realistic conditions?”
A test sequence could involve different forces, movements and cycles to reproduce an expected usage pattern.
