Simulation types
|
Kinematic Analysis
Kinematic Analysis: Examines the motion of assemblies without considering the forces that cause it. Focuses on parameters like velocity, acceleration, and the trajectory of moving parts
|
Dynamic Analysis
Dynamic Analysis: Goes a step further than kinematic analysis by considering the forces and moments causing the motion. Analyzes the effects of loads, inertia, damping, and other forces on the movement of assemblies
|
Static Analysis
Static Analysis: Evaluates the system under static (non-moving) conditions. Focuses on how forces and moments are distributed across the assembly when it's in a steady state
|
|
Flexible Body Dynamics
Flexible Body Dynamics: Involves the study of components that deform under load. Takes into account the bending, stretching, or compressing of parts, unlike rigid body dynamics
|
Vibration Analysis
Vibration Analysis: Examines how oscillatory forces affect the system. Crucial for understanding and mitigating unwanted vibrations that could lead to noise issues or mechanical failures.
|
Fatigue Analysis
Fatigue Analysis: Assesses the durability of components by simulating repeated loads or movements over time. Helps in predicting where and when a part might fail due to material fatigue
|
|
Thermal Analysis
Thermal Analysis: Looks at how heat affects the motion of parts, or conversely, how motion affects temperature changes. Particularly important in systems where thermal effects significantly impact performance
|
Multi-body Dynamics (MBD)
Multi-body Dynamics (MBD): Simulates the interaction of multiple interconnected bodies in a system. Considers their mass and the forces acting upon them
|
Impact Analysis
Impact Analysis: Studies the effects of sudden forces, like crashes or drops, on the system. Especially relevant for safety evaluations in the automotive and aerospace industries
|
|
Contact Analysis
Contact Analysis: Focuses on how different parts of an assembly come into contact. Includes the effects of friction, wear, and impact
|
Control Systems Integration
Control Systems Integration: Involves the study of mechanical systems with integrated control logic or electronics. Examines how the control systems influence the movement of mechanical parts
|
Optimization Studies
Optimization Studies: Involves adjusting parameters within a given design space to find the optimal design. Focuses on criteria like minimum weight, maximum strength, or optimal performance.
|
|
Parametric Studies
Parametric Studies: Similar to optimization studies but focuses on understanding how changes in parameters affect the behavior of the system.
|
Coupled Physics Analysis
Coupled Physics Analysis: Combines multiple types of physical analyses (like structural, fluid dynamics, and thermal). Examines how they interact in a single simulation
|
Realistic Contact Mechanics
Realistic Contact Mechanics: Accurately models the physical contact between components. Considers how they touch, slide, collide, and exert forces on each other
|
|
Friction Modeling
Friction Modeling: Detailed modeling of frictional forces at contact points. Includes static, dynamic, and rolling friction models
|
Adhesion and Cohesion Forces
Adhesion and Cohesion Forces: Models adhesive or cohesive forces between surfaces. Necessary in micro-mechanical or biological applications
|
Soft Body Contact Modeling
Soft Body Contact Modeling: For simulations involving soft materials, like rubber or biological tissue. Accurately models how these materials compress and interact
|
|
Surface Roughness Effects
Surface Roughness Effects: Accounts for the effects of surface roughness on contact interactions. Significant for performance in certain applications
|
Multipoint Contact Handling
Multipoint Contact Handling: Ability to simulate contact scenarios involving multiple points of contact simultaneously. Essential for complex assemblies
|
Contact Force Calculations
Contact Force Calculations: Precise calculation of forces at contact points. Necessary for assessing stresses and predicting material behavior under load
|
|
Interference Fit and Preload Analysis
Interference Fit and Preload Analysis: Analyzes scenarios where components are press-fit or preloaded. Affects the stress distribution and overall assembly behavior
