ESTECH.PRIMESPEC

Feature

• Calculate engine rigid body excitation forces under operation condition.
• Calculate kinematic motion of primary parts of a reciprocal internal combustion engine, translational forces, moments and crankshaft output torque fluctuations induced by combustion pressure for each order tracking component.
• Additionally, inserting primary specifications of engine inertia properties and engine mounting specifications enable engineer to calculate rigid body vibration of a power plant of a vehicle.
• As far as the combustion pressure is concerned, external data measured by physical test as well as data calculated by the optional function of the software are used.
• Since whole operations are conducted on Microsoft Excel, which is from inputting design specification to analyzing output, even non-CAE specialist can easily use it for design studies.

Application Example

• Design study of primary specifications of dominant moving parts as well as layout of cylinders of a reciprocal internal combustion engine
• Design and layout study of an engine balancer shaft
• Design and layout study of engine mounting system
• Calculate loads to an engine crank pin
• Combining the engine model (mass and forces) with kinematic mechanism analysis vehicle model or FE vehicle model makes it possible to simulate noise & vibration phenomena such as booming noise and idle shake

Overview

Name	ESTECH.PRIMESPEC
Function	Calculate engine rigid body excitation forces working on a power plant of a vehicle by inserting primary specifications of engine dominant moving parts and combustion pressure as input. The calculated excitation forces make it possible to simulate rigid body vibration of a power plant suspended by engine mounts.
Calculation conditions	Combustion pressure on/off Balancer shaft with/without Constant rotational speed
Applicable engine models	Engine with single cylinder to 12 cylinders, Inline, V shape and Horizontally opposed 4 cycle engines Engine with unequal combustion intervals
