Our Services

Zenshin Engineering provides advanced engineering simulation and design services that help manufacturers, EPCs, and asset owners validate, optimize, and de-risk critical systems before they are built, tested, or commissioned. We work across switchgear OEMs, EPCs, utilities, data centers, and industrial facilities.

Electrical System & Switchgear Simulation

We simulate the behavior of electrical systems under normal, abnormal, and fault conditions to improve safety, reliability, and compliance.

Services include:

— Arc flash and short-circuit studies
— Protection coordination and relay discrimination
— Load flow, voltage drop, and capacity analysis
— Switching transients and power quality studies
— Digital twin and lifecycle modeling

Outcome: Safer systems, fewer outages, and validated compliance with IEEE, IEC, and NFPA standards.

Thermal Simulation (CFD / FEM)

We analyze heat generation and dissipation within switchgear, enclosures, and electrical equipment to prevent overheating and premature failure.

Services include:

— Temperature rise and hot-spot analysis
— Busbar and conductor thermal optimization
— Enclosure ventilation and cooling assessment
— Material and geometry optimization

Outcome: Improved reliability, reduced material cost, and extended equipment life.

Structural Simulation (FEA)

We evaluate the structural integrity of electrical and mechanical assemblies under operational and fault conditions.

Services include:

— Static and dynamic stress analysis
— Short-circuit force and fault withstand evaluation
— Deformation and fatigue assessment
— Structural optimization and weight reduction

Outcome: Structurally sound designs that meet performance requirements without over-engineering.

Multibody Dynamics (MBD) & Mechanical Motion Analysis

We simulate mechanical motion, interactions, and forces in moving assemblies to validate performance, durability, and reliability.

Services include:

— Mechanism kinematics and dynamics
— Contact forces and joint loading
— Vibration and shock response
— Actuation and switching mechanism analysis

Typical applications:

— Circuit breaker operating mechanisms
— Switchgear interlocks and moving components
— Mechanical linkages and drive systems

Outcome: Smoother operation, reduced wear, and improved mechanical reliability.

CAD Modeling & Engineering Documentation

We support all simulation work with accurate digital models and complete engineering documentation, ensuring designs are ready for manufacturing, installation, and review.

Services include:

— 3D CAD modeling of components and assemblies
— Parametric models for design optimization
— 2D manufacturing and fabrication drawings
— Bill of materials (BOM) support
— As-built and revision-controlled documentation

Outcome: Clear, manufacturable designs aligned with simulation results—reducing rework and uncertainty.

Integrated Multiphysics Design Approach

Our simulations are not performed in isolation. We integrate electrical, thermal, structural, and mechanical analyses into a single, coordinated engineering workflow.

This allows us to:

— Capture real-world interactions between physics domains
— Identify risks that single-discipline analysis can miss
— Deliver practical, implementation-ready recommendations

Outcome: This integrated approach is a core differentiator of Zenshin Engineering, enabling comprehensive design validation that single-discipline analysis cannot provide.
